English Posted March 22, 2016 Share Posted March 22, 2016 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.

Kiwideziner Posted March 22, 2016 Share Posted March 22, 2016 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.

English Posted March 22, 2016 Author Share Posted March 22, 2016 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 Alan Link to comment Share on other sites More sharing options...
Joe_Carrick Posted March 22, 2016 Share Posted March 22, 2016 Scale factor should be 12. Your Contractor seems to be working in feet rather than inches. Link to comment Share on other sites More sharing options...
English Posted March 22, 2016 Author Share Posted March 22, 2016 I must have been having a senior moment as it was obvious that it should be x12 -- 30" = 30' so 1" = 12". Alan 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 Posted March 23, 2016 Author Share Posted March 23, 2016 Sorry about that faux pas. Didn't know that I was giving myself credit. Alan Link to comment Share on other sites More sharing options...
