When we export a DXF file that needs etching, we have to open
the DXF in DWG Editor and manually change the etch marks to blue
line color. Sigmanest, our laser program, see the blue lines as
etch marks. We name the etch sketches in the model "Etch1". Is it
possible to export certain geometry as a different color?
At least that is what I am seeing.
Hope this helps.
