Question
I draw parts for cnc machine. When I dxfout they grow like 3 times the size of the dwg. What can I do to stop this? I'm using autocad 2002.

Answer
I communicated via email with Herb on this one.  I suggested that he check out the computers that are making the different size drawing files.  There could be a computer that is using a vertical product of AutoCAD that is loading up the drawing file with invisible proxy data, like wall styles, footing styles, door and window styles, etc.  I told him that ADT and Architectural have -AECPURGE.  I gave him a macro for a toolbar button that would work in Architectural.

Herb:
I'm checking into this.  There is no answer off the top of my head, so, this could take a while.  Can you tell me exactly how much everything is getting scaled?  That might give me a clue.

update 8-17-07:  Still no answers.  Most people haven't a clue as to what could be going on.  This is a problem that is almost unheard of.

8-19-07:  Some say there might possibly be an inches versus metric scaling issue, others say it could be the software that is reading the DXF.  If you send the DWG and the DXF to me at bdeshawn@sterling.net, I'll will check them out and see what I can find.
