i need to rescale some plans from 1:15 to 1:24. i want to get them photocopied to make life easy, after doing some maths i think i need them copying at 64% the original size

does anyone have any experience of doing this? if so could you pass on that experience cos this is giving me brain ache!!

cheers

toptugger......  15 divided by 24 = 0.625.....or a 62.5 % requirement of the original size........some Plan Printing companies have sophisticated computerised machines that will reproduce plans @ exact % reduction/increases ....however some less capable machines will reduce one plane [say X] by a true 62.5%....however the other plane [Y] may be distorted by approx +/- 2%  ......Derek

Hi

I scale plans every day
I never use a photocopier to scale plans for the reasons already stated
How I do it is

Scan the drawing you have,
Run it through Scan2Cad
Clean it up and orientate it
Transfer it to Autocad
Scale it to 100% size
As the original drawing may not be true to scale
Try and find either a scale register or some other feature that you can get to verify the 100% scale
When I am happy with the drawing I save it as a 100% version
In your case where you want 1=24 scale I copy the drawing inside Autocad and scale accordingly
It is then printed on a HP Designjet printer at 1=1
I never scale the 100% drawing itself I always use a copy and save it, identfying it when I save it with the scale within the title name

In my local newspaper.There are usually a feww advertisements from people who will draw plans fof a home extention etc.They
will have access to a large photocopier.The gentleman i dealt with was  able to rescale to my required size at very little cost.John

If you don't have AutoCAD or any other CAD program at hand but can frequently use a large format scanner and/or printer, I would recommend this combination:

- Scan plans with high definition (600dpi or better), write as TIF with CCITT4-compression (= b/w)
- Re-size plan to the required scale percentage using IrfanView (small,quick, very versatile and utterly reliable freeware available at http://www.irfanview.com for those who don't know it yet).
- Print the resulting TIF into a PDF document from IrfanView, thus creating a PDF based on the correct sheet size (I use FreePDF from http://freepdfxp.de/ but there must be zillions of free PDF generators out there)
- Print plan copies from PDF file using the "scale = original" at any copyshop that supports large size plots.
- Repeat step 2-4 for every re-scaling operation you want to do.

You will find a Scale Drawing Conversions Chart at www.ipmsstockholm.org>Magazine

They are all rounded up to a full percent.

Hi johns,

you will find the conversion chart at the thread I sent earlier.Its in TechTips. Workshop Tips.

hope it is of some help.
