I’m not an Autocaditor unfortunately, I use Catia for such things. Tried importing into VCarve, exporting as svg then importing to CC and it choked. Tried importing, exporting, several different ways from VCarve and couldn’t get anything CC would read as a matter of fact, but Inkscape didn’t like it either. Don’t have Catia on this PC to try either.
Maybe contact the author? I think it’s on Inventables.com
