I’ll send it to the support address.
Regarding the workarounds:
1.) I always work in mm and as shown in the settings screenshot, everything is already in mm. Might the other way around also work, i.e. regenerating it in inches?
2.) I don’t think I have ramps but I’ll check
3.) I couldn’t find an option to disable generation of arcs. Do you happen to know where to do that in Fusion 360? Is it one of the options shown in the screenshot above?
