CAD are you interested....
« on: October 05, 2012, 01:30:34 am »

Hi All,

I have started this thread as recently there has been a bit of interest in CAD (Computer Aided Design.
Me personally I have an interest commercially in both CAD & CAM (Computer Aided Manufacturing)
But as a modeller I have an interest in building & helping others.

Perhaps a new section on this forum could help us all get a better understanding of what can be done in each discipline without getting any ‘backs up’

Have a look at Ian's X bow & tutorial on Delftship as an excellent example of how we could help each other ..


If your viewing this then you have a computer and maybe soon the chance to get on the 'wave'

Perhaps if enough interest then Martin a new title could be created for us?

I will leave it at that for just now..

Regards,
Kim

With the print quality and price of Home 3d printers improving all the time this is certainly a good time to start lookiing into CAD.

Im using Google sketchup at the moment for drawing up some prototype parts for printing on our 3d Printer, but will be moving on to something a bit more powerful at some point.
I am also dabbling in Home 3d scanning which again is something thats coming to the fore

Would you consider that these are other suitable subjects that could be bundled under a new CAD/CAM section?

What are the potential benefits for us boat modellers for 3d scanning?

3d laser scanning means you can scan a 3d object (For example a full size boat part) rescale it down to you chosen scale using a cad package and then either have it 3d printed or cut on a CNC

Im currently tinkering with the free laser scanning software and a laser... results have been promising so far
With a webcam and a line laser as the only real hardware required its quite cheap to get a taster for it

3D scanning has some application for very complex shapes that woud be extremely difficult to model e.g. a human head, perhaps your own (god complex, anyone?)

I'd say for 99% of what you're likely to want to print for a model boat, 3d modellling is swifter and simpler.

What will really make things interesting for the modeller is if modellers start to pool their resources and talent. Create a library of 3d models that modellers can either print themselves or have sent to a bureau.

Hmm, this is all very interesting, and I like the idea of a pool of scans, files etc.

What I think would be really useful is a beginners guide to what types of files needed, and software to use in preparation for laser/water cutting and 3d printing.

A section on CAD would be good in my opinion, I was a drawing office manager and have extensive knowledge (including a lot of setting up and configuring) of both AutoCAD and Microstation, and am always willing to lend a hand or give advice on CAD.
reviews on different CAD packages would also be useful, I also have inkscape on my machine.
As I have mentioned I am using CAD to draw up a set of plans of a Friends boat so that a model can be made of it,

Hi All
I read this subject with great interest.
I am a retired Design Engineer with experience (40+ yrs) and have prepared files for all of all the modern manufacturing processes
I can assist this subject by running the database of files etc.
I can also assist members with their drawing problems and conversion to the various file types.
I can model using 3D solid & surfacing techniques.
I have considerable experience in problem solving in the design and drafting area
I can turn your sketches into 3D models and the relevant files for manufacture ( no matter which method you choose )
My current software library includes
Autocad R14
Pro Engineer Wildfire 2
Catia V5  R15

Yes... i am very interested in CAD. Because I'm a graphic designer, I use Illustrator and Indesign, so I think I would pick it up quickly. I just cant afford a copy of the program.

could be interesting too - i used auto cad lite and rhino and various plugs ins on rhino....


we also use 3 d modelling packes that are  unique to  our craft.....

i have to get help from  colleagues overseas on some of the tasks because theyre beyond my skills !

 funnily enough in the new year we will be building another huge ship, the hull will be designed and modelled in rhino first then imported into our unique software... but i know the results will be good... my colleagues did this  different vessel the same way..

to get the free educational version of autocad you need to go here - http://students.autodesk.com/?nd=home
the  requirements you need to qualify to get a copy are -
Quote
Eligibility Requirements

To participate in the Autodesk Education Community, you must agree to and comply with the applicable Terms of Use and also satisfy the following eligibility requirements. You must be one of the following: (a) a faculty member; or (b) a student; or (c) an Autodesk Assistance Program participant.

A faculty member is an employee at a primary or secondary educational institution or any degree-granting or certificate-granting educational institution or any learning, teaching or training facilities and who upon request by Autodesk is able to provide proof of such status.

A student is an individual enrolled at a recognized degree-granting or certificate-granting educational institution for three (3) or more credit hours in a degree-granting or certificate granting education program or in a nine (9) month or longer certificate program, and upon request by Autodesk is able to provide proof of such enrollment.

inkscape is quite a simple Cad style program from here http://inkscape.org/ open source so free.
bentley microstation has an educational (academic) version - http://www.bentley.com/en-US/Engineering+Architecture+Construction+Software+Resources/Academic+Educators+Students/PowerDraft+Download.htm I'm not too sure what you need to qualify, but it will work in trial mode even without a licence
(at one time I did find a university in australia that had their lisence file on an open webpage for their students - not that I am encouraging this of course)

Sign me up for this one!

I'm trying to get into this CAD lark and have been trying to design a Yorkshire Coble as a 3D model and then onto the bits being water jetted and then assembled. I did try previously with a more complicated design, which got to the water jetting stage, however these frames are now in the heavens as I got sick and burnt the lot...

I then started a new design and seem to have it perfected. I then (probably the slow way) I created frames and imagined how they would lock together in my head. I then designed the 2D frames and then read up on how to simply assemble 3D parts in Turbocad. Below are a few screenshots of the assembled jig, proving that all my measurements worked:















This is something ive never been able to do and I have been trying for ages to do this and it finally worked!

The next stage is to attempt to 'wrap' the 2D planks I have round this frame. However I don't think turbocad can do this, not even autocad, and is more a rhino thing.

The programs I use are Freeship and Turbocad v18.1 platinum and have access to Sketchup Pro aswell.

I am a modeler who would rather draw something on CAD and have it CNC'd or 3D printed and then integrate that part into the model I am building.

I look forward to seeing where this thread goes.

AutoCad, Hmm, the Myford of drawing program(me)s. Not all that draws is (or even neccessary to be) AutoCad. There are many freebies out there for you not to have to think about lining the pockets of the industry "Standard" supplier of yesteryears.

  I wonder how many reading this thread will think that using whatever 2, 3 or even 50D programme will make them into a "Designer".

Before jumping in at the deep end, what are the minimum requirements regarding equipment, namely the PC, processor, monitor, operating system et all.

In a nutshell can I do all this CAD, CAM, CNC (CNC not spelled out) on my home PC running XP. {:-{ {:-{

Will the tutorial be styled similar to 'CAD for Dummies' for instance.

Im far from a designer, I probably create things in the most inefficient and long winded way possible, however i manage in the end.

We all have to start somewhere and would love eventually to be able to use autocad and inventor to the max and design allsorts of stuff.

I appreciate it takes years to get to that stage and probably 20 degrees or something, but most here will have played with some form of CAD and are interested to use it in the hobby.

Looking forward to seeing where this thread goes.

I can run CAD on my 3 year old laptop running XP, its slower. for work now I run cad via remote desktopping on a machine in the office, good enough for the few hours a week I work.
Its only now  I have the time that I am able to really explore 3D in CAD in my microstation package I can lay down planking one at a time with the twists, but have encountered the odd occasion where a plank will twist 180 degrees between frames, which sort of spoils the look.
