DWG Export with incorrect units
-
I've got a SU model in millimeter units. When I export to 2D DWG it sets the DWG units to Inches so I have to manually correct the units every time I export to 2D DWG.

Units can be tricky sometimes. Keep playing with the units both in SU and CAD. Look at how they are off. i.e. if you cad drawing are 2.54 times bigger, you'd know inches is getting in there and messing up the scale somehow. Also, be sure in CAD you start off with the <units> command.

Thomthom,
SU uses the correct units when exporting, but there is IMO a bug in the exporter, as the internal scale flags in the resulting DWG file all point to inches all the same, so unless you take care, AutoCad will import the file 25.4 times too large.
I have resolved this by turning all import scaling off in AutoCad. It involves setting a small bunch of system variables, most of which can be accessed through the Units command. I never need AutoCad to scale my imports, so I have set all these to Unitless.
