Issue With DWG & DXF Import

Recommended Posts

My contractor has an inexpensive CAD program Viacad 3d v9 and he says he draws everything at full size (as he should) but when he sends me a DWG or DXF file it imports at a scale (that I have yet to determine).  Any idea what is happening as I don't want to have to scale everything before converting the lines to walls?  He says that he goes to Files>Export>DWG.

Thanks

Get him to put a couple of dims and re export and send, you will then be able to work out the scale factor.

as a guess one or other of you may be setting units at mm instead of inches in the export/import process.

I got a dimensions and it seems as if it's 1" = 10' as a wall that measures 2'-6" should be 30'  However when I scale the drawing I'm not getting what I want and I'm having a brain freeze. :)  What should I scale up to get to a full size?
Thanks

Scale factor should be 12.  Your Contractor seems to be working in feet rather than inches.

I must have been having a senior moment as it was obvious that it should be x12 -- 30" = 30' so 1" = 12".

BTW I found out that his CAD software will not let him draw full size -- it defaults full size to I' = 1".  I've always been taught that you draw full size and only scale to print.

English,

 

It's bad form to give yourself the "Best Answer".  You should give the credit to the person who gave you the answer, not yourself.

Sorry about that faux pas.  Didn't know that I was giving myself credit.  :(
