Title: Delftship tutorial
Post by: boatmadman on August 22, 2009, 06:12:31 am
Some kind forum members suggested I do a Delftship tutorial :o So, here goes, but bear in mind its all self taught and I am no teacher O0

Ok then, after some thought I think a relatively simple hull to demonstrate how the program works is the best way, so, lets begin!
First off, download the free version from:  http://www.delftship.net/
To get started, click file:new and you will get the window below. Enter the dimensions you want to start with, in this case 6 points in longitudinal direction, 5 points in vertical direction,29.26m Length, 7.62m Beam and 2.13m Draft. (some of you may notice these are the dimensions in mts. of Perkasa). Make sure units selected are M, (or ft. if you want to work in old money).
At this point I want to point out that I think its easier to design at full size and when you are happy with the shape, scale down to the size you want to build at.


Sorry, pic didnt load, have asked Martin for advice.

Now we need to temporarily remove some of this information to make the screens easier to work with. Go to project: hydrostatics and you will get this:
Title: Re: Delftship tutorial
Post by: boatmadman on August 22, 2009, 02:09:26 pm
In the ‘display hydrostatic features’ box, untick the tick boxes and then click ok, you should get this now:
Title: Re: Delftship tutorial
Post by: boatmadman on August 22, 2009, 02:11:46 pm
For now, leave other selectable features in the boxes we have looked at in default values, they can be changed later if you want to.

Now is a good time to SAVE AS (filename).

In the perspective window (top left), click and hold left mouse button and move, you should see the image zoom in and out. Click and hold centre button and move will rotate the image, click and hold right button moves the image across the screen. Note, the left and right buttons work the same way in all windows, but the centre only works in perspective view.

Next, deselect the options shown with white arrows, and select the one shown with the red arrow. This will allow us to see an uncluttered view of what we have so far.

Hi Overpowered,

Delftship is a lot of fun, but you need practice to get anywhere with it- it can be quite tedious for the first couple of designs, but well worth the effort- and your lucky enough to have a tutor too!!! :o

Keep up the good work Ian :-))

Here's my current Delft' project, a 30' x 6' fast steam launch design.

And you should have this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic6.jpg)

Right click in the perspective window and select mode:shade to give you this:

We now have a basic hull, but without a transom !! That will come later.

There is a lot to do yet to get it to resemble an MTB hull, but bear with me.

Remember: SAVE, SAVE and SAVE  and do it frequently as you go along.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic7.jpg)

Now it’s time to start straightening a few lines out, let’s start with the keel. Click the button ‘show control net’ to get this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic8.jpg)
Title: Re: Delftship tutorial
Post by: boatmadman on August 23, 2009, 12:10:38 am
We want a flat keel from the transom to the curve of the bow, so, working in the plan view, (bottom right), left click on the furthest left control point (black dot) on the centreline. You will see this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic9.jpg)

Now, press and hold the ctrl key and left click on the next four control points working to the right, you will get this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic10.jpg)

No doubt you will have seen the little pop up box shown above. In the z coordinate enter the value 0.0 (zero) and you will get this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic11.jpg)

Now, I think we should refine the shape of the deck a little, then we can refine the hull shape between deck and keel: Click the define control net off, then on again, this removes any previously selected point.

In the profile view, starting at the left edge (transom), select four points along the top edge and assign the value 3.8983 to the Y coordinates. Sometimes, for reasons I don’t know, with this operation the hull shape goes nuts, if so, go to ‘edit’ and undo last operation and re enter the value. You should now see this: (I have moved my perspective view a little, yours may be different in this window)

Title: Re: Delftship tutorial
Post by: boatmadman on August 23, 2009, 12:52:39 am
I think now is a good time to look at the transom. Select the three control points shown:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic13.jpg)

And give them the value 3.8983 in the Y coordinates box. Now select the control point up from the keel, ensure no others are selected and assign it the value 0 (zero) in z coordinates. You should have this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic14.jpg)

Next, select the points shown and move them to the same width as the transom:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic15.jpg)

Again, select the points shown below and move them to the keel line:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic16.jpg)

(http://i239.photobucket.com/albums/ff219/boatmadman/pic17.jpg)


Title: Re: Delftship tutorial
Post by: boatmadman on August 23, 2009, 12:57:04 am
I think we should define the turn of the bilge next. To do this right click on the perspective view and select mode: wireframe. Next click on the lines shown in yellow below, yours will be black but turn yellow when you click on them:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic18.jpg)

Now, go to edit, edge and click crease, you should get this, with the control net turned off:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic19.jpg)

Now we can see the bilge line running from the stern towards the bow, with the beginnings of the chine starting to show.

Next, I think we will close the transom using the extrude tool. Reselect the control net on, and click on the three lines shown:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic20.jpg)

Title: Re: Delftship tutorial
Post by: boatmadman on August 23, 2009, 01:05:52 am
Go to edit, edge, extrude and in the transverse direction box enter-3.8983. This will close the transom back to the centreline:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic21.jpg)

With the control net off and the hull shaded, you should have something like this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic22.jpg)

Ok, not much like a Perkasa type hull at the moment, that’s due to the program giving too much freeboard (I think!), so lets sort that out next.

Select the five points shown and give them a z value of 2.2194 to get:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic23.jpg)

Do the same with the next horizontal line up, assign the value 4.9732:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic24.jpg)

Select all the points shown below, then, go to transform, move and enter -1.7 in the vertical axis to give you this: (the bow will be sorted out later)

(http://i239.photobucket.com/albums/ff219/boatmadman/pic25.jpg)

Repeat the last operation on the deck line, using the value -3.1. You should have this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic26.jpg)

Lets make that bow look a bit better now.

 In the profile view, left click and hold on one of the control points that is out of line and drag it until the red line looks better. Repeat that for the other out of line points, then turn off the control net to see the actual bow line. You should have something similar to this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic27.jpg)

 I think that’s enough for now. Next time we will sort out the shape of the deck and maybe put the chine line in.

Post by: boatmadman on August 23, 2009, 04:49:36 am
Lets have a look at the shape of the bows at deck level now. Getting the shape we want at deck level will make it easier to shape the rest of the bows later.

Select the control net on and have a look at the bow area. You will see only one control point between the bow and the sides that we previously worked on. This wont allow us to produce nice faired lines around the bow, so, we need to add more control points in this area.

Select the control lines shown:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic201.jpg)

And click edit, edge, split. You will have something like this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic202.jpg)

Without changing anything else, now go to edit, edge, insert to create extra control edges:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic203.jpg)

Repeat the above for the section immediately aft of the bow to get:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic204-1.jpg)

Now I have just noticed that there is an edge missing where I have circled above, so, to put that right, select the two points shown:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic205.jpg)

And click edit, edge insert to create the line:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic206.jpg)
Title: Re: Delftship tutorial
Post by: boatmadman on August 23, 2009, 04:56:29 am
To work on the bow shape, simply click and drag a control point until you get the desired shape.

This will require you to keep adjusting all the points until you get the shape you require.

 Work in the plan view window whilst doing this, you can see the shape change clearly as you work.

Below is a grab after moving just one point:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic207.jpg)

And here with a nice bow shape at the deck.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic208.jpg)


Now, boys and girls, I would like you to work on the remainder of the bow to make it look about right. Try and aim for something like this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic209.jpg)

Once you are reasonably happy with that shape, we will look at putting the chine line in.

You will see below that I have split two control lines, the new points are in yellow:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic210.jpg)

Select the points shown in yellow:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic211.jpg)

And insert an edge as we did before.

 Now select the edges as shown in yellow, and click edit, edge, crease to get:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic212.jpg)

And we have a chine line, but you will see it needs adjusting. Do that simply by drag and drop control points.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic213.jpg)

To see a lines diagram of you model, select view, linesplan.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic214.jpg)

The deck line doesn’t look so nice now, so I think we will address that next.

There is a tutorial for scanning line drawings and using them within delftship. I havent used it myself, so cannot comment on it, but its here:

http://www.google.co.uk/url?sa=t&source=web&ct=res&cd=1&url=http%3A%2F%2Fwww.boatdesign.net%2Fforums%2Fattachments%2Fdesign-software%2F33338d1248034181-step-step-design-your-boat-tutorial01.pdf&ei=MjSRSq3COsyhjAf8sMTJDg&rct=j&q=delftship+tutorial&usg=AFQjCNFixMtN16ezIqLrCdCMdBpedUmw0Q

Post by: boatmadman on August 24, 2009, 02:55:49 am
I know I said we would look at the deck line next, but I think the chine line needs more attention first.

I think it needs to be lowered at the bow, so here goes.

Select the two lines shown and uncrease them. To do this, after selecting the red lines, go to edit, line crease and they turn yellow and are no longer part of the chine:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic301.jpg)

Insert new points and connect them as before, then crease the new lines to give you:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic302.jpg)

Remove the two lines that are no longer part of the chine using edit, edge collapse. Then manipulate the new chine line until you are happy with it:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic303.jpg)

Now that has been improved, the deck doesn’t look as bad to me so I will leave it for now.

I do think though that the boat would look better if the beam narrowed slightly from midships towards the transom.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic304.jpg)

So, that’s a basic hull done, easy huh?

What I haven’t talked about yet is working with layers.

 When you start to build up components of the model, it’s a good idea to assign each component its own layer. This allows you to move and/or manipulate each component individually as well as give different colours to the components.

To demonstrate this I will put a deck on the boat using a new layer. Click the button layer properties, you will get:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic305.jpg)

Give layer 0 a name – hull is a good one for this! Then create a new empty layer using the new layer button, give it a name – deck, and choose a colour for it.

Select deck line and extrude by -4, same method as we used for the transom.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic306.jpg)


Title: Re: Delftship tutorial
Post by: boatmadman on August 24, 2009, 03:01:05 am
This looks wrong because we have extruded every point equally, despite the curve of the deck.

To correct this, click the button – show both sides of the model –select the points you just extruded and give them a y value of zero, they will go to centreline, now show both sides of model again and you have this, or something like:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic307.jpg)

Now we have to think about fairing the hull. Fortunately with this model, the curves are reasonably good, but I will demo how to do it.

Unfortunately, with the free version, fairing has to be done manually, if you have paid for the full version, you get an auto fairing tool – nice!

Turn on the control net, select the deck edge:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic308.jpg)

click the button arrowed above to get :

(http://i239.photobucket.com/albums/ff219/boatmadman/pic309.jpg)

Turn off the control net and select the curvature button and you will get something like:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic310.jpg)

This shows that the curves I have are quite smooth, easiest seen in the plan view. Just to demo what you will see if you have a bad curve I will move a point on my plan view:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic311.jpg)

You can see that as the line changes curvature, the pink lines get larger or smaller depending on the curve. Before you try this, save your model, then have a play.

Of course, you need to fair the whole hull using this method, this is where it becomes time consuming and sometimes frustrating!

The best thing now is to experiment, practise really is the best way of learning this software.

I hope this has been helpful.

Hi Ian Thank you very much for this tutorial it's most helpfully . I down loaded Delftship and had a play could not get it to work. I have work thought your step by step tutorial and I have ended up with a hull the same as yours.
A few question come to mind.
How did you come up with the values to put in X and Y
the hull you have done  has a far few lines/ curves in it but how would you go about a more complex hull like your Xbow or a life boat hull which has tunnels in it for the props. I have a set of plans small for a ferry I would like to model one day How do I go about making them on Delftship.

John
Title: Re: Delftship tutorial
Post by: boatmadman on August 25, 2009, 04:58:35 pm
Glad the tutorial worked for you John.

The y values I used at the transome was the distance the point furthest away from centre was at the aft end, this moves the extruded aedge to the centreline and created the transom.

The z values used for lowering the deckline were arbitrary values just to make it look ok.

To add more control points, select the control net on, then in tools click subdivide control net. This will do as it says on the tin subdivies the net.

Alternatively, you can increase the control points in a particular area by selecting the lines in that area and splitting them. You then need to add an edge to join the new control points.

I showed how this is done at the bows in the tutorial.

You need to be cautious about how many more control points you add, as the more there are, the more difficult it becomes to get nice fair lines, unless you have the pro version of course.

As a rule of thumb, I keep control points to a minimum in areas where the hull is straight or nearly so, and add only at curves.

For your plans of a small ferry, have a look at the other tutorial I posted the link for, it tells you how to develop a model from an imported set of lines. I havent done this myself so cant comment on how easy/hard it is. I will try to have a go soon though.

With my xbow, I started off in exactly the same way and added more lines, control points as I needed them. Its a slow process but satisfying, especially when you start building a model you designed yourself. Time will tell how it behaves on the water though!

Post by: cos918 on August 25, 2009, 10:33:05 pm
Hi Ian just had a look at that other tutorial . I have put a plan as a back round in Delftship. The only thing is suddenly  there to many line so I am going to redraw the plan removing all but essential lines. I can now see were you got the values for X/Y/Z now. It look a very promising program.
When you do a line plan and in the head on view to the bow you can see all the frames . Was it these you printed out in the making of your X Bow.

John
Title: Re: Delftship tutorial
Post by: boatmadman on August 25, 2009, 10:38:51 pm
John,
The view onto the bow gives you the lines from the bow to midships, the stern on view gives the lines from midships to stern.

I printed these out, then used a pantograph to enlarge to the size I want. Ok, I lost a little accuracy with the pantograph, but I didnt have access to a printer big enough for A3 paper and the local printshop has shut down >>:-(

Ian,

thank you very much for doing this - your tutorial is so much more useful than that which comes with DefltShip.

I'm starting to understand how powerful this can be - apart from the fact that it took 10 minutes to figure out that I needed to split two lines to create the new point for the chine...

I really appreciate your efforts - thanks!

There is a tutorial for scanning line drawings and using them within delftship. I havent used it myself, so cannot comment on it, but its here:

http://www.google.co.uk/url?sa=t&source=web&ct=res&cd=1&url=http%3A%2F%2Fwww.boatdesign.net%2Fforums%2Fattachments%2Fdesign-software%2F33338d1248034181-step-step-design-your-boat-tutorial01.pdf&ei=MjSRSq3COsyhjAf8sMTJDg&rct=j&q=delftship+tutorial&usg=AFQjCNFixMtN16ezIqLrCdCMdBpedUmw0Q

This appears to be the tutorial that can be downloaded from the DelftShip website. I have used it previously and didn't find it particularly helpful - the only thing in it that might be useful that Ian hasn't covered is setting up the background image/line drawing, scaling it and getting control points to match the drawing.

Otherwise, for shaping a hull and learning DelftShip, Ian, your tutorial is much better.
Title: Re: Delftship tutorial
Post by: boatmadman on August 27, 2009, 11:55:44 am
I am currently working through the download background image tutorial hopefully to enable me to understand it, and if possible, translate it into another tutorial to post on here.

It may be a little while coming, as I am not finding it particularly easy to get through!

Ian
Title: Re: Delftship tutorial
Post by: boatmadman on August 28, 2009, 09:01:29 pm
Having had a play around with importing background images, I think I can now simplify the delft tutorial.

First of all, you may ask, why import a set of lines when you can use them to build from?

Two reasons spring to mind – and there may be more:
•   You have a set of lines for a hull design you wish to modify in some way
•   Your lines diagram is a photocopy and has lost some detail in enlarging. This method should give you a diagram at the scale you want with the accuracy you desire.

So, lets go:

For this demo I am going to import the lines plan from the earlier demo and hopefully we will end up with a similar hull again.

First open a new file and enter the starting details as shown.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic401.jpg)

Remove the clutter as before:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic402.jpg)

will start of working in one window only, so, maximise the plan view:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic403.jpg)

Right click on the page and background image, load to get:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic404.jpg)

Right click and select background image, origin.

 Now left click and hold down while you move the mouse and the background image will move as you move the mouse.

Move the image so that the bottom left point on the centreline coincides with the same location on the hull model

(http://i239.photobucket.com/albums/ff219/boatmadman/pic405.jpg)

Select background image, set scale and the cursor changes to a ruler, set the point over the bow point at the centreline and click:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic406.jpg)

Title: Re: Delftship tutorial
Post by: boatmadman on August 28, 2009, 09:09:40 pm
The pop up window is asking you to set the scale of the model using the dimensions of the imported plan.

We know from the last tutorial that the model is 29.151m long, so, enter 29.151,0 in the box.

The zero entry is the ‘y’ coordinate which in this case is zero because we are working on the centreline:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic407.jpg)

This all looks pretty confusing, so lets clean up the background a bit.

Right click and set background image, transparent colour and you get a little dropper as a cursor. Hover over the white area and  left click:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic408.jpg)

Adjust the intensity of the image with background image, blend. Do this to suit your own preferences.

Now do background image, tolerance. I set my value at 250:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic409.jpg)

Repeat all that with the profile view:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic410.jpg)

And the bodyplan view:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic411.jpg)

You will see here that the stern looks out of place, this is due to the shape of the hull at the moment and will be corrected later. 

If, when you are setting the position in this operation, you find that there is a vertical or horizontal offset, just re align with the origin tool.

Select all the curves on the model:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic412.jpg)

Click edit, curve new. Turn off the control net and you should have something like this:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic413.jpg)

The next instalment will, I think, deal with moving the model about so it looks the same as the imported image.

Right, lets see if we can match up the deck line first. On the profile view, select the deck line:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic514.jpg)

Then expand the plan view:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic515.jpg)

Now start moving the deck line points. Start at the stern and work forward.

Two ways of doing this:

1.   Select a point by left click and drag to where you want it.

2.   Select a point and move it with your cursor keys.

Drag and drop is quicker but you run the risk of moving the point in other planes as well as the one you are working in. I.e. In this case we are working in the x/y plane, using drag and drop can sometimes cause the point to move in the z plane as well. Don’t ask me why ‘cos I ain’t got a clue!

If you find the incremental distance of a cursor key is too big, on the bottom left of the screen you will see a label – incre.  Distance: xx. Click on that and in the window select a smaller value.

Here we can see that I have aligned the deck line to the background:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic516.jpg)

Moving on to do the same with the keel and bow, we get this weird catamaran thing:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic517.jpg)

This is because we have moved the control net for the keel, but not yet for the sides, we will do this next.

Using profile view, select each point in turn on the side of the net and move in the x and z direction until the lines look something like this: (note, you can only move one point at a time, this is where it can get a little tedious, especially if you have hundreds of points!)

(http://i239.photobucket.com/albums/ff219/boatmadman/pic518.jpg)

One thing to note at this point. In the body plan view, delft outputs the lines diagram with a bow on view and a stern on view, but when working with the program, these are combined, with aft view on left and bow on right.

So, at this point, align the control points for the stern in the body plan view.

Bear in mind this is an iterative process and you may well find yourself moving a point more than once.

Anyway, in time, you will end up with something like the original plan, hopefully identical! Mine isn’t in this tutorial, as I want only to show how to do it, not achieve a perfect copy.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic519.jpg)

Then you can fade out the background image using the blend tool:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic520.jpg)

Now, we have developed a 29m boat! Too big for the workbench? Thought so,  lets scale it down a bit.

Go to transform, scale to get:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic521.jpg)

When you do other models working with layers, decide whether you want a global scale and tick all the boxes, or be selective for specific layers, in this case with one layer just make sure it is ticked and click ok:

Decide what scale you want, lets say ¼ scale here, and enter as shown:

(http://i239.photobucket.com/albums/ff219/boatmadman/pic522.jpg)

Click ok and you have a quarter scale model. Go to project, dimensions and you will see the new sizes.

(http://i239.photobucket.com/albums/ff219/boatmadman/pic523.jpg)

Well, I hope this has been helpfull. If there are any questions, I will try to answer, but, remember, I am self taught on this and ther is still loads I dont really understand.

Hi everyone!

First, thanks for this great tutorial. It has helped me understand how Delftship/Freeship works. There is one thing that's not clear to me yet: how can one print out sections of the hull at points where you want your ribs placed?
Title: Re: Delftship tutorial
Post by: boatmadman on March 01, 2010, 08:30:03 am

I dont think you can print at sections like you ask, I wanted to do the same and couldnt find out how. It may be possible on the pro (paid for) version.

Ian
Title: Re: Delftship tutorial
Post by: kno3 on March 01, 2010, 09:16:27 pm
Thanks! Anyone tried with the pro version?
Or how do you proceed to cut ribs after the Freeship drawing?
Title: Re: Delftship tutorial
Post by: DavieTait on March 01, 2010, 09:31:42 pm
One way to do it would be to have the lines on screen and press the "Print Screen SysRq" key , then open up a photo editing program ( or paint if thats all you have ) , start a new image at your screen size ( usually 1024x768 ) then right click "Select All" , the Right Click and "Paste". In Photoshop you then have to hold down Ctrl and the E key before saving not sure about paint.

You can then print the lines out and use them that way I guess

Hi kno3,

Yes it is possible to do surface generation with FreeShip, the images in my post above shows the plotted 3D model and the image in my post lower down shows that plank developments for the same hull form.

Your options are;

1 Pay the £100 price tag for DelftShip or

2 Find the original FreeShip program in the net.

Try here

http://freeship-plus.pisem.su/downloadsE.html

Or if I can work out how to transmit files from my hard drive over the ether I have them.

There is also an active Yahoo Groups webpage with tons on hints and tips plus users efforts in the files and photos section.

http://groups.yahoo.com/group/Freeship_HTandT_Group/

If your having fun with FreeShip/Delftship it might be a good idea to sign up :)

Post by: Greggy1964 on March 12, 2010, 11:10:29 pm
Ok here we go, bear with me cos I aint touched FreeShip in over two years

We are going to walk through how to create 'Plank Developments' using the jpeg images below.

Its a quick overview to get you started and then you should get the idea.

Expand the number of planks you require by splitting the control points to adjoining panels and creasing the new control lines to create any number of planks you desire.

I'm going to use the default boat you see when you open up a new file in FreeShip.

Here goes

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step1openupdefaultboat.jpg)

Open up the default Boat, I'm using the 3D veiw because it's easier to see what's going on.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step2highlightchine1anddoEdge-Creas.jpg)

Select the control lines 1st up from the keel, we are going to crease this edge using the 'Edge/Crease' command and create a chine at this point.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step3highlightchine2anddoEdge-Creas.jpg)

Do the same process for the 2nd set of control lines.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step4highlightchine3anddoEdge-Creas.jpg)

You will notice as we progress the previous set of control points will have turned Red

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step9selectshowinterioredges.jpg)

Now go to 'Show Interior Edges' (the little red box with the crossed lines in it) and you will notice a new light green grid appear.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step10selectinterioredgesplank1ands.jpg)

Starting at the stern select each panel on Plank1 (the light green grid will turn yellow), then go up to 'Layers' (found between Face & Visiblity) in the menu bar and select 'Auto Group'

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step11openLayersandrenamePlank1.jpg)

Open up the 'Layer' menu and you should see a new layer has appeared, re-label it Plank1

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step12selectinterioredgesplank2ands.jpg)

Do the last two steps for the next plank up . . . . . .

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step13openLayersandrenamePlank2.jpg)

And label the new layer in the 'Layer' menu Plank2

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step14selectinterioredgesplank3ands.jpg)

And again for the next plank up . . . . . . . .

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step15openLayersandrenamePlank3.jpg)

And again for the next plank up . . . . . . . .

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step16selectinterioredgesplank4ands.jpg)

Now we should have four new layers, Plank1, Plank2, Plank3 and Plank4, I just used layer 0 for Plank4 beacuse Layer0 is redundant for our purposes here. You could create a Layer5 and relabel it Plank4 if you wished and keep Layer0

You should now be able to go back into the Layers Menu and be able to switch each plank off in turn and leave only the plank visible you wish to see, this confirms that each of our 4 planks have a dedicated layer each.

Think of them as four layers of tracing paper laid one on top of the other with one plank drawn on each.

Now comes the clappy handies and jump up and down moment.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step9selectshowinterioredges.jpg)

Make sure that the 'Developable' check box is ticked for all four planks in the 'Layers menu' (found nestled in the checkbox list to the right)

Then go to 'Tools' and select 'Develop Plates'

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Step18gotoToolsandselectDevelopable.jpg)

Hey Presto! four brand spanking new developed planks.

The cool thing is that it produces a set of planks for both sides of the boat.

Look over to the right, and check the list of errors. None of them should be greater than 0.001 if the printed planks are to fit together.

The file can now be exported as a DXF file for use in AutoCad or exported as a BitMap or simply sent to a printer.

For those of you who are lucky enough to have a copy of AutoCad the file can be manipulated to create plank outlines at any scale you derire.

Be aware though that the plot aussume infinite thinness of developed planks so when you transfer them to plywood which has thickness you will have a spot of edge shaving to do to make them fit.

Dig out the cereal boxes I'm forever getting you to save and print out the file at A3 and spend a couple of hours with a roll of cellotape making a little version of your new boat!

Of course if we bothered to go to the trouble of adding a stern panel to out boat, that would be plotted too, but that's opening up a whole new can of worms!

Enjoy!

In the isometric view, if we right click in the image and select 'mode' and then 'developability check' we can see if our baby will actually be transformable into flat developed panels

Red area indicates stretching and deformity and it always appears to some extent on the planks adjacent to the keel but can be minimised by tweaking.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/DevelopabilityCheck.jpg)

The image suggests some concaving of the first planks at the bow which if I worked on it it could eliminate it, but for this project the model serves its purpose.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/ShadedHull.jpg)

Right clicking again and selecting 'mode' and then 'shade' gives us the above. :-))

When in the developed planks file, if we select the little blue 'pyramid' button in the menu bar the plot will show us more graphically the stretched areas which indicates more work in shaping the planks is required.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Plank%20Development/Stretchedareasofdevelopedplanks.jpg)

We would do this by altering the lines of the hull bit by bit and redeveloping the planks until we find the blue areas have been worked out of the planks.

Have a play but watch out . . . . . .  :police:

It gets addictive :-)) O0 %% %% %%
Title: Re: Delftship tutorial
Post by: Greggy1964 on March 13, 2010, 01:22:48 pm
Another thought! :-))

A good way to eliminate that ugly sore area at the bow of the first plank would be to split this plank up into still thinner planks.

Think of broad planks on three penny bit style boat with its simple shape dictated by its form.

And now contrast this with the sexy concave hull forms that can be had using the strip plank method of building.

So what IS he  >>:-(   blathering about I hear you wonder? <*<

Well, I'll explain . . . . . . . . :-))

The narrower the planks on our model, the more we can introduce hollow bows without that ugly red area that says ''nope! you can't have hollow shapes within a plank of plywood''

Remember! A piece of paper/carboard/plywood cannot form compound shapes.

Try it if you don't believe me, and no crinkling it or crumpling neither! O0 :police:

Thats cheating. {-) O0

But it can be fooled into two directions at once . . . .

How you may ask?

Form a sheet of paper into a cone and see for yourself.

More thoughts :-))

FreeShip can represent a multi-planked hull as I have demonstrated, and by deciding how many planks you want per side on your hull at the start; you end up with some nice hull forms.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShip%20Hull%20Designs/P1.jpg)

This is my 'Swift' sailing canoe hull design and she has ten planks per side which gives her hollow lines while not infringing the 'no compound curves within planks' rule.

I messed about some and came up with a multi plank version of the default hull just to show what can be done.

*'BEFORE PLAYING WITH YOUR LOVELY MODEL SAVE IT AS 'MULTI PLANK MODEL'* or some such and work on the NEW model so if you fluff things up there will be no  >>:-( tears  >>:-(

also *'SAVE'* as you go along so that you don't loose where you have got to.

I know I'm teaching Grandma to suck eggs but I've fallen foul of this before so I'll save you the trouble :-))

I used the same method I described in my 4 plank hull in the post above. O0

Use the 'Edge' 'Split' command at each of the bulkhead wire frames all along the hull between each existing plank, you can select all sections between planks at one go and do the 'Edge' 'Split' all at once to save time.

Here is the wire frame with both sides of the hull
(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/WireFrameHull.jpg)

Next comes the shaded hull - bow on
(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/ShadedHullBowOn.jpg)

Then stern on
(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/ShadedHull.jpg)
Note the lovely hollow shape we now have at the bow compared with the four plank hull in my above post.

Then developability check
(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/PlankDevelopabiltyCheck.jpg)
The red areas on the plank seams is a bug I think because the program has no trouble plotting the results and the error indicators on the right of the plank plot are in the order of 0.000000 error. :-))
Look closely at the . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  figures V V
(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/PlankDevelopment16Planks.jpg)
And finally all those lovely planks - 16 of em! I have only plotted the port side because if you plot both sides the image comes out too small to show here :-)) :-)

It has taken me about 1 1/2 hours to knock this up so with practice you can get good results. :-))

My original sailing canoe design and indeed the model I built from this design called for clinker (or overlap/laps strake - call it what you like - fill in the blank   ...............) style planking. O0

You could take the developed planks and add the overlap manually and get clinker planks I think . . .

But I'm sure FreeShip will be able to deal with the concept, but as yet I haven't tried it . . . . . . . .

hmmmmmmm

Great addition to the tutorial, Greggy.

I have had a play with delftship, and found that by following your instructions, you can do almost the same as you have done with free ship.

I say almost. The bit you cannot do is pretty important to us. You cant export or print the file of developed planks! <*<

I think this may be because Delftship took over the freeship software and probably disabled that feature to try and get more people to buy it.

Hello Boatmadman,

I confess I have not tried to print out the resulting planks of late, when FreeShip originally popped up it was a new development and the guy promoting it was a naval architect/computer boffin type collage student with a bright idea who put it in the great ether as a full working program. O0

I guess he did this to gauge whether or not it would be a viable commercial product for him back then.

Buying the current evolution of FreeShip costs 178.00 Euros or £162.00 or $244.89.

It is only fair that the fellow should be rewarded for his efforts in providing us with such a useful software, it's how the world works after all, and at a very reasonable price too considering that you could set yourself up creating boat plans for yourself and others for a   <*<  financial inducement   <*<  of course!

And I for one (when I am in a financially fluid situation) will buy a copy.

But contrast this to the price tag of AutoCad2010 at a cost of   :o 1290.00 Euros or £1168.00 or $1774.00  :o   and the cost of buying Delftship starts to become attractive and the bonus is that you have then a fully developed software specifically geared to Naval Architects with all the knobs and whistles! :-))

Don't be put off by this by the way, naval architects put their underwear on every morning one leg after the other like all the rest of us lowly beings :-)) It's just a learning curve at the end of the day :-)) and if you enjoy what your doing and have a passion for it, then it becomes play and not work!

There is somewhere lost in the great ether is the original beta copy of FreeShip, I am not sure that the copy I have on my PC is the original ( I lost that with a hard drive meltdown a couple of years ago!  >>:-( >>:-( >>:-( ) and I'm not at this time I confess, connected to a printer or plotter so I cannot test my current copy out.

I will endeavour to do some digging :-))

If in the meantime anyone else reading this witnessed the birth of FreeShip and can shed any light on the whereabouts of the original Beta copy, we all would  :kiss:  love you forever  :kiss:  :-)) O0
Title: Re: Delftship tutorial
Post by: Greggy1964 on March 14, 2010, 12:39:24 pm
Yet another thought on the plotting issue of the plank development plan.

Boatmadman's comments set me thinking and I've come up trumps!

Cheers Boatmadman :-)) O0

Do all the required steps above to get you to the developed planks plot for your model.

Blow it up to full screen and look closely.

You will see a grid behind the planks with measurements from a zero base line at the centre of the plot.

You also have the option to zoom into any area to read the mesurements.

Also by switching off all parts of the model except the plank you want figures for, the plank development plot will only plot this plank

The figures you see are measurements from the base line to the edges of each plank at the frame positions you set in your model.

The more wire frame sections you build into the model, the more sets of these measurements you will get and the more accurate will be the planks you plot from this info.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/Plankplotmeasurements.jpg)
In this shot the measurements in metres are given to plot the full scale ship planks on the mold loft floor.

Right at the beginning of a new model in FreeShip you have the option of setting scale, measurement type and the number of frames in your new boat, it can also be accessed at a later date during the creation of your ship.

The plank plot will give those mementos in the resultant plank plot.

How difficult is it going to be to grab a suitable sheet of paper, a bunch of dress makers pins, plus a suitable board so that you can push pins through the paper at appointed plot positions, and grab some various sizes of piano wire, spring it around the pins on the paper plot and draw out your planks out manually?

I can see this as no greater hardship than the way model builders traditionally find the shapes of planks, plus the bonus it that you just know all the resultant planks will fit together and form your dream ship :-)) ;)

I will create another tutorial here to show you how to manipulate the plot to get the results you need.

Watch this space :-))
Title: Re: Delftship tutorial How to grab measurements for planks from the plank plot
Post by: Greggy1964 on March 14, 2010, 01:30:57 pm
Right I'm here again.

Fun this isn't it? {-) {-) O0 O0

I'm using the default multi plank model above for continuity.

Grab your plank plot and resize it full screen on your monitor.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/PlankPlot1.jpg)

Here are all 32 planks.

In your plank plot window, press down your right mouse key and drag the toolbox on the right to the centre of your screen and then roll your mousewheel to zoom in.

The whole plot will pan across the plot window and grow on you until you see what you're after.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/PlankPlotToolBox.jpg)

You will see this image.

You may if you wish switch off all the plank images but the one you are working on.

There are three boxes that you may enter data into, the top one sets the rotation of the whole plot in the current window.

The second sets the measurement SPACING of the required plotted plank edge figures in the X axis, and the lower box is same for the Y axis.

Changing these figure will cause the plank plot to redraw showing the required measurements.

Play about with this after you have saved your work so far so you can hurt your original, save it as *'Plank Play'* some some such.

Now you can mess about and explore with a free conscience :-)) O0

Note I have set the figures I require in these boxes.

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/PlankPlot1Zoomedin.jpg)

Here, the plotted plank dimensions are at X 0.500m and Y 0.500m

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/TailendofPlank1Zoomedin.jpg)

It is not too clear on the screenshot, but to the left we have the horizontal zero line datum and the vertical.

Use the right mouse button and the scroll wheel to zoom into the measurements you are after and scribble them madly down in a legable format on a note pad for each plank.

Depending on the number of planks you have on your model and the measurement spacings you have set, you're in for an evenings worth of panning/zooming and scribbling.

The more closely the plotted measurements, the more accurate will be your paper plot and the planks you draw out.

But at the end of the day you will have a bunch of figures to set out the planks of the full size ship!

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/Plank6sternend100mmspacings.jpg)

Here is the stern end of plank 6, now we have a zoomed in on an image of the stern end at X = 0.100m and Y = 0.100m spacings of dimensions.

Have fun boys but don't pee off the missus with your new found addiction! {-) {-) {-)

Of course it goes without saying that when you have written down the notes in your notepad . . . . . . . you have converted each measurement to the scale of the model boat you want! %)

Haven't you?      >>:-( >>:-( >>:-( >>:-(   {-) {-) {-)

Alternately, let delftship scale it for you. Select transform and you get a scaling option in the dropdown, select the size you want, and Bob's yer Auntie :-))

Hi Boatmadman,

You're right :-)) that does work!

I'd missed that one

(http://i431.photobucket.com/albums/qq32/greggy1964/FreeShipDefaultHullMultiPlanked/BowendofPlank11-12scaleZoomedin.jpg)

Same hull but scaled to 1/12 scale, here we have the bow end of both planks 1 with rotation setting at -2.5/2.5 degrees, X Grid 0.005, and Y Grid 0.025.

Note all measurements are taken from the zero line to where they cross each plank edge.

Also, if you switch off all planks but the one you're dealing with, you can rotate it over the grid and the measurements will change accordingly. O0

One thing to watch is that the software cannot subdivide measurements smaller than 1 mm so at small scales you will still have a little fairing to do while plotting you planks on paper, as the software was designed for plotting planks out at full scale.

i.e. 125mm scaled down by 1/12 = 10.417mm, the software would round down to 10.000mm which will make a difference when you're trying to fair in points along a curve.

You can see this problem by studying the plot above.

Maybe I'm being a perfectionist %)

In those cases where you want accuracy I'd still suggest plotting full size and converting the measurements by the multiplication factor as you transfer them from plot to note pad

Hello! I am a newcomer on this forum, and also on Delftship !
First of all : BRAVO to Ian and Greggy1964: Delftship seems suddenly almost easy ! I have achieved the modelling of a small and simple hull !!
It's just a basic hull only used to understand and "play" with it, that I can easily modify. So, it's rather good !!
But I have a real problem with the modelling of the deck, or rather with roof and companionway, and so on...I don't succeed in modelling these parts...

Does somebody can help me, please ???

Hello Phil,

The trick with Delftship as with everything else computer and file based is to save your work regularly and work on a copy of your drawing as things evolve.

You can't 'break' anything this way and it will allow you to freely explore the Delftship environment and play with it.

If you fluff up, it's simply a case of going back to a good copy before things went pear shaped! {-) O0

I confess to have not explored the issue of decks and upper structures too much thus far, choosing to concentrate on hull shapes only.

I too am interested in such a tutorial and bow to Ian's greater knowledge. :-)) O0

Delftship – a brief tutorial on developing decks and superstructures.
This is a model hull of a fast rescue boat I am working on to go with my current project.

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic1.jpg)
 
First thing to do is open the perspective to full page, select wireframe and work with just half the hull – it’s easier to see.
You should have something like this.   
At this point, select a point at deck level at the widest point of the hull and remember the Y axis value in the dialogue box that pops up. Here I used the point at the transom, but any point the widest point will do.
 
(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic2.jpg)

Now, select the bulwark line to get the pic below.

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic3.jpg)
 
Title: Re: Delftship tutorial
Post by: boatmadman on April 01, 2010, 09:46:12 pm
Go to edit, edge, extrude and enter the value you remembered in the transverse value box, also, put a minus in front of the value, to make it a negative and press enter, and you should have this:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic4.jpg)
 
Now deselect the yellow line, and select all the points on the new extruded line and give them a ‘y’ value 0, this will move the line to midships, and give you this,.

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic5.jpg)
 
Now, select the new deck area as described earlier in the tutorial series and group into a new layer, name the layer ‘deck’ and give it a different colour, grey in this case
 
(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic6.jpg)

Right click on the pic, select mode, shade. Then show both sides of the model and you should have something like this.

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic7.jpg)
 
Superstructure to follow soon.
Title: Re: Delftship tutorial
Post by: boatmadman on April 01, 2010, 11:35:15 pm
And now a superstructure:
Select the line on the centre line shown, extrude in y direction by 1.75m, you get this, or something like.

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic8.jpg)

Continue the extrusion vertically up:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic9.jpg)

Select the lines as shown above and extrude back to centre line:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic10.jpg)

To get a cubic shape, select the 2 edges in yellow above, and crease them to get this:
(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic12.jpg)
Title: Re: Delftship tutorial
Post by: boatmadman on April 01, 2010, 11:43:17 pm
Deselect the grid, select shade and both halves for this:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic11.jpg)

Now go back and insert an edge:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic12.jpg)

Select the two points on the new edge and give them a vertical value of 4.8, (arbitrary value to get a vertical position)

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic13.jpg)

Now select the top edge and move it forward 0.6m:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic14.jpg)

Select the yellow edge and crease:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic15.jpg)

Title: Re: Delftship tutorial
Post by: boatmadman on April 01, 2010, 11:46:57 pm
Build another superstructure ‘box’:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic16.jpg)

Go back to wireframe and add a box for the funnel:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic17.jpg)

Move it around a bit to make it look pretty:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic18.jpg)

Throw some paint at it and voila:

(http://i239.photobucket.com/albums/ff219/boatmadman/deck%20tutorial/pic19.jpg)

Hopefully that should give you enough to start building your own decks and superstructures.

Hi

I was wondering if you could do another tutorial to show how to add superstructure to a hull and of course equipment on the decks I am a serving Chief Officer on a brand new Dive ship being built in Norway and I would like to draw the vessel using Delft Ship.  As Chief Officer I can get hold of all the drawings etc from the designer so I can import them but I cant get the Superstructure to work, and I have come to an abrupt halt.  I wanted to use delft ship to make a PT boat, out of wood but I would also like to make a model of the ship I am working on using delft ship.

Your help in this matter would be greatly appreciated, I love the drawing of the Bourbon Boat, and I love the models too, I have never made a model before thats why I wanted to start with the MTB and work upwards.

Many regards

Craggsy

Post by: boatmadman on May 11, 2010, 05:42:41 pm
Craggsy

What part of the superstructure are you having trouble with? You should be able to do it using the tutorial I did.

I think you will have to develop all the deck clutter from basic shapes - cubes and cylinders - and work them into the objects you want.

Its possible the pro version may have more of these functions, but I cant be sure as I have never used it, I am a cheapskate really!

Ian
Title: Re: Delftship tutorial
Post by: Craggsy on May 12, 2010, 05:11:35 pm
Hi

I hadnt seen your tutorial, so I will follow that closely, and get back to you, a Dive ship has loads of structures like Tautwires and transponder beacon winches and dive bell launching equipment on the sides as well as cranes and lifeboats etc etc, but at least now I can get to grips with the main accommodation block.  Hopefully when I rejoin my ship in June I can send you some drawings or post them on the forum or something maybe then you can see what I mean.  The model will be too complicated for me so I am going to draw some plans up using Delft ship for an MTB or something like a PT boat and try and make that to start with.  Your tutorials are brilliant and I am slowly getting the hang of the software, so much easier than AutoCad.  Thanks for all the help!!

Thanks to all contributors to this tutorial, helped me a lot to find my way around in freeship.

Am trying to get acquainted with the basics of how to model a hull in FS, managed more or less al the steps as described in this tutorial (so far) but still couldn't figure out how to create a cambered (main)deck.
Extruding the deckline at side to a deckline at center is clear but creates a "flat" deck (transverse) with the sheer at centerline being the same as the sheer at side.
I'm aiming at a cambered deck, arc shaped with a segment height (at centerline) equal to 2% of the beam (at midship section) of the hull.

Anybody here who know's the trick?

Jasper
Title: Re: Delftship tutorial
Post by: boatmadman on November 16, 2010, 09:56:10 am
Jasper,

I dont think there is an easy way around this in the free version, the Pro version MAY do it for you, I dont know.

I have achieved what you are looking for by manually moving each point to the desired position and fairing the resultant curve. You can lessen the work needed by temporarily removing some stations and control points, set the position of the remaining points  to give you rough curves and then add more stations/control points as required until you get what you are looking for.

Hope this helps

@Ian,
Thx for your reply, looks as if there is no easy way to get the result I want.

Have found a way, more or less as you say, by manipulating points.
To illustrate wat I've done sofar (it's not a worked out model, I'm just trying to find out how to do surface modelling with this software), a few screenshots are attached to show the method I used to get my cambered deck.

Background info, my starting point is the bodyplan together with the table of offsets of a multi-chine launch of appr. 9.00 (L) x 3.00 (B) m.
The camber in the maindeck, at full B, is set at 60 mm with a circular arc as profile; segment heights at buttocks 0.5 and 1.0 m can easily be calculated to get the decheight at these points.

What I did:
step 1) imported (as surface) the offsets of 3 frames, see pic 1,
step 2) created a deck by extruding the deck at side edge and entered the co-ordinates of the 3 points at the inside deckedge as given in my offsets for deck at centerline, see pic 2,
step 3) splitted the 3 transverse decklines (twice each) to get additonal control points and entered the (calculated) co-ordinates of the points at the buttocks,, see pic 3.

result: see pic 4, looks like a nicely cambered deck.

A long way to get there, an easier way might be by adding control points ("in space") with the co-ordinates for the deck and then creating a new face.

Hi guys Im new to the forums here. I have delftship but am haveing a ton of problems. I did the tutorials and stuff and thats sorta ok for me for little rowboats but I have 2 warships I have been working on and I cant figure out how to finish them off also one of them really got screwy looking. I am trying to learn this as I need to do a hull for a 1/72 yamoto and a 1/72 USS Missouri so that when I get to Arizona in a couple weeks I can CNC the hulls out while im there with access to the equipment. can someone help mentor me on what I am doing wrong? I saved them as 3.6 version as its easier to swap with most anyone. I am willing to make the hulls available for anyone that wants once I get them finished.

Title: Re: Delftship tutorial
Post by: Proflooney on December 09, 2010, 08:31:58 am
I posted my yamoto if someone could look at. i'm not sure how to add more stations though or get the proper shapes for the stations. I think I got the outline covered but don't know if I can do the hard corners the way it is currently but now would be a good time to crease the outline edges to get the shape im needing then get to the hard stuff like shaping the hull

my files at http://www.proflooney.net/yamoto.zip

I saved it as version 3.6 so that its compatible with most ppls

Title: Re: Delftship tutorial
Post by: boatmadman on December 09, 2010, 09:07:52 pm
Joe,

Nice work.

To add stations, on the 'view toolbar' toolbar, click on the item that looks like a hull with a pair of scissors under it, you will get a window open called intersections. open the left most icon and you will get a list of stations. To add, either click on +1 and specify the distance, or, click +n and fill in as required.

Hope this helps.

I will try it. but my question is I dont know where to go next on this hull. I mean I got some corners that need to be a sharp bend and not sure hoe to make them sharp. and for shation shape to I have to take the lines that I used on the station view and add more of the nodes to adjust the shape more. lol im just so confused right now as I can always get to this point and then get lost as to where to go next. then in the rear buy the deck theres a weird notch cut out of the hull im not sure where to go with that ie how to do it

Joe

Post by: Proflooney on December 12, 2010, 01:39:09 am
Ok guys I am learning more and more but have 1 question thats kinda hard for me to explain. I am going to set up my own grid bullock and station lines at the scale of my drawing and use the ones in the program that I create rather than on my drawings so I can clean things up on my screen and so that way the program will produce a nice set of scale drawings for me.

my question is do I need to still give the proper dimensions at the setup screen or can I just leave it at the default if I am going to manyally input all that stuff later?

Dan
Title: Re: Delftship tutorial
Post by: boatmadman on February 17, 2011, 09:25:32 am
Joe,

Apologies for not answering your question sooner, but regarding dimensions, as long as you input dimensions that are 'sensible' at the start, as you develop the hull, you can scale in all directions as you need to get the sizes you really want.

I have found that working at dimensions close to full size, then when you are happy with the results, then scale to the size you want gives the best results as it reduces any little limps and bumps in the profiles.

Regarding to noobies tutorial, maybe a new thread would be the way to go, then people can work with the one most relevent to them without being fazed by the more advanced stuff.

Dan, I havnt worked with plate development, but I will have a look when I can grab some free time.

Title: Re: Delftship tutorial
Post by: fatcat123 on February 17, 2011, 10:21:07 am
I was playing on freeship last night on the latest version only released a few days ago.

I'm currently building a whitby coble from scratch and have measured up the real boat in every place i possibly can. The boat has 21 ribs and obviously a transom. I have measured the distance between each rib and the beam at each rib in order to get an overhead profile of sorts.

Now aswell as other measurements, is there a way to basically input my measurements so that i can get the correct overhead proflie straight away? I have also measured things like the depth of the hull at certain points. Assuming this could be done and i had the perfect coble on my screen, is there a way then to create like a internal profle to be used for things like the ribs and the actual jig used to lay the planks onto as its clinker built. I would also need an overlap on the planks for that reason.

Dan {:-{
Title: Re: Delftship tutorial
Post by: boatmadman on February 17, 2011, 11:04:14 am
Dan,

I think you may have to input the points individually, I cant think of any other way - doesnt mean there isnt another way, I just dont know it!

Regarding clinker build, if you follow the tutorial from post 51, and then when you have the planks shaped up and ready, you could scale in the appropriate direction - not f/a to give you the overlap you need whilst preserving the required curves. Alternately, you could select all the points on a curve you want to move to create an overlap, then move them all by the same amount in the direction you want.

I havent actually done this, so it might be a good idea to make a smaller hull first to prove the process?

When you have the hull completed, if you then create a linesplan you will get a set of half profiles at each station you have created along the hull. You then need to make a copy of each profile and use it as a template to make your building profiles.

These can also be used to create any ribs you may need to be a permanent fixing in the hull.

Hope this helps.

Ian

Aslong as it can be done then i shall try. I havn't found a way to enter the beam measurements etc but will have a good read over the thread again and see what i can come up with. Theres a distinct lack of tutorials on this program on the net  :((

Post by: boatmadman on February 17, 2011, 11:19:15 am
If you look at post no 17, you will see the hull profiles as a linesplan. this is the starting point for cutting out a set of building profiles.

Been messing around on freeship on and off for the last week in an attempt to model a 33ft Whitby Coble for a new build im going to do. Its not perfect but the shapes there and it just needs a little evening out.

its been very difficult to say the least in getting to this stage even though I have the full size boat which I measured up. The model even has the prop tunnel.

Opinions please!

Thanks to Boatmadman (& Greggy1964) for two very helpful and easy to understand tutorials.  For a novice at both model boat building and CAD it was (and will continue to be) an extremely beneficial reference.  I have taken the liberty of copying all the relevant posts to two word documents so that now I have a ready offline reference whenever I need it.  Also makes it much easier to do the tutorial offline as I have two monitors and can run the word document on one and Delftship on the other.

Thanks again for all the effort you have put into this.

As part of my current build, I needed a fast rescue boat. Being unable to find one to buy at the size I want - 100mm long I thought I would put to test using freeship to develop a model and print out plank developments and see if the theory held out!

The first pic shows the plates cut out and ready to transfer onto plastic.

The rest of the pics show the build stages as I add the planks.

I only used one station along with the transom due to the size of the thing - it was fiddly!

Anyway - this is where its up to now.

Whilst it has proved that freeship can be used this way, I am not entirely happy with the outcome, but that is due to the difficulty in building at that size I think!

Hi Ian

I've never tried anything like this before - a complete lack of confidence - but having read this thread I think I will now at least have a try. So Thanks for posting the tutorial.

Dave, its a bit like when computers were new have a play you can't break it ..... having said that i have been to the computer repair shops many times   in the past ...  :)


Zaf -
if you can work with 3d models or import them to a cad programme then the likes of  -

TurboSquid
3dStudio
websites have 3d models available to purchase ... nothing for nothing I'm afraid.

Kim

Hi Zaf,
That's possibly a bigger question than i have time to give answer to .

If you have a capable Cad programme then it should be easy enough ...

Hi Zaf,
Have a look at this http://www.modelboatmayhem.co.uk/forum/index.php?topic=29834.50 You'll see some plans near the bottom.

You have to imagine the plans as layers, then take them apart and cut out each layer. These are your frames.

Thanks again.Do u know how i can scale it?And what is the distance between frames?
Title: Re: Delftship tutorial
Post by: wartsilaone on February 24, 2012, 02:04:31 pm
I usually get plans scaled for me.
Others may have better,easier ways but this is the way I scale up images at home:-

Download GIMP  (Gif Image Manipulation Programme)
Open the image
crop the first frame
go to the image tab and select 'scale image' You can do it by millimetres or percentage, which ever is best for you.
check that the print size is the same size
print your first frame

repeat the steps for each frame

If you scale up the side view by the same amount as the frame and print, you can measure the distance between frames.

Thank you Boatmadman, your tutorial has been an inspiration. Your instructions are clear and concise.

Here is one I've had a go at. The draught is a bit deep and the length is probably wrong because I used a cargo ship as a template but I can tweak it.

Title: Re: Delftship tutorial - printing frames
Post by: boatmadman on May 26, 2012, 11:23:16 pm
I have often wondered if I could get frames drawn in DS. Well, I have found its possible, a little fiddly, but possible.

(http://i239.photobucket.com/albums/ff219/boatmadman/frame%20tutorial/skeleton.jpg)
 
The next step was to find a way of printing each frame individually without having to fork out for the full delftship version.
I tried loads of different programs, cad, dxf readers, pdf, xyz, abc…all with no workable solution.
Then, bingo! Found a way.
You need to draw each frame as an individual layer and then open it in bodyplan view with the control net off….
This screen grab shows the midships frame of the model above:

(http://i239.photobucket.com/albums/ff219/boatmadman/frame%20tutorial/bpview.jpg)
 
Next, right click on the screen and you get a little pop up box, select print and you get…..

(http://i239.photobucket.com/albums/ff219/boatmadman/frame%20tutorial/Delftshipbodyplanview4105596468068.jpg)
 
Now, you can either save it to print later, or print straight from this screen.
Unfortunately, its not quite as easy as it seems, at this stage you will probably have to fiddle around with scaling on your printer to get to the size you want.
Again, fiddly, but it can be done,

Hi all,

Today been fiddling with a new project on freeship. It still is of a Whitby Coble, however it has been re-designed how it should have been. Taken about 6 hours or so to convert offsets in ft, inches and eighths into decimal for freeship.

Hi Ian,

I also have been mulling over how to produce actual building frames, that can be directly printed out and glued onto the ply wood for cutting, from my lines plans I have created in DELFTship (DS).
Preferably I also would like to do that from DS in situ rather than exporting the stuff (e.g. File->Export->DXF 2D Polylines->checkbox crossed "create individual files"),
and then having to import it again in another CAD program to further modify the frames therein individually (e.g. reduce planking shell thickness, construct inner frame contour with cut outs and recesses for keel, stringers etc.)

My problem with this approach is that I first and foremost lack such a back end CAD software (that should run on Linux and should be free to use).
I have given DraftSight (http://www.3ds.com/products/draftsight/overview/) a try but haven't been able to import to it any DXF files exported from DS.
So it's been pretty useless. Also I am not versed in the usage of a CAD program.

I already have created quite a few lines plans with DS which I believe are usable for building a model hull from them.
E.g. let me take this hull of a ferry (http://www.modelboatmayhem.co.uk/forum/index.php?topic=28467.msg418307#msg418307) that I have created recently to show you where I cannot follow you.

So would you mind to elaborate a little further on how actually to take a layer of an individual body section.
Sorry, but your statements above are a little too terse to me.

I try to attach a screen shot that I refer to, and which I hope will appear below.

The sections that I usually have DS displayed once my hull model is reasonably fair are those that I call Simpson Stations as I follow the frame spacing convention from traditional manual lofting practice where these distances were required for numerical integration of areas by Simpson Rule.
So it's usually Lpp/20, and at the hull endings Lpp/40.

I use the DS Intersections menu to arrive at those stations.
I never constructed or faired them individually, and I even wouldn't know how to do that with DS's internal hull model where one only manipulates the grid nodes of the defining polygon/polyeder.

I prefer using the same Simpson Stations as actual building frames in my model construction because I got used to it when lines plans where obtained as paper copies from the shipyards.

In the screen shot below I have selected via Intersections menu Simpson Station 17, i.e. with an Lpp = 148 m of the original vessel, 125.8*20/148.
I activated the pink hatched curvature display (which can be scaled a little by hitting F9 (smaller) or F10 (larger)) so that one can see the selected station.

Now, how would I have to create a new layer of this particular station then?
Could you please explain to me?
As far as I know, layers can only be defined for selected (i.e. yellow) points and edges of the control grid.
But my control grid points don't coincide with the 2D polyline points required to define the selected station 17 spline.

Regards
Ralph

My method is by no means the best way or the only way, however I basically imported the linesplan into turbocad and copied the 'station' and did a mirror copy and then modifying this within cad to make notches in it for framing etc.


You can then go into 3d space and since you already know the spacing of the 'stations' then its fairly straight forward to position the frames to be able to loft the sections and create the hull. if it has curves and twists then Rhino will have to be used to unroll (flatten) the loft.


Take a look at this thread - http://www.modelboatmayhem.co.uk/forum/index.php?topic=39886.0 (http://www.modelboatmayhem.co.uk/forum/index.php?topic=39886.0)


I must add that for my design, i used freeship which was delftship before it changed its name. It allows as a free version, the plates to be developed and exported directly as a 2d.dxf for use with cnc work.


I havn't really messed with the delftship stuff and as far as i know, you cannot develop plates on the free version.

Hi All,
Im wading through freeship programme and trying to get a catamaran hull design started using the data supplied.
Can any one walk me through the process,  if this is at all possible with this programme.

Many thanks

Man I been using Solidworks forever and been trying to mess with delftship on a design I got and having absolutely no luck. just getting into shipsand found nice drawings for a mission boat but cant seem to get it going anyone still use this program?
