Thanks for helping me figure this out. Sounds like v2.0 will take care of most of this stuff.
It does export if I make the box parts into a standard custom part, but until v2.0 it doesn’t cut the dado for the box bottom panel.
It’s no big deal. I can make the parts on a separate layer and import them from VCarve. If I want to nest all the parts in one go, that’s easy, too. You can import the extra stuff after you open one of the CabWriter DXF’s, that way they all get nested and cut at the same time.
