@BG : just so you know, MOI3D is actually incredibly powerful for 2d drafting/drawing. It may not have drawing constraints like regular 2D CAD software, but the speed of use in incredible. It's so powerful in fact that I've personally started to use it for freehand 2d sketch work (as in : with a graphics tablet) besides regular CAD drafting. I do sometimes wish it had proper parametric drawing/history features, but in practice editing is just so fast that it isn't even needed.

It is also way, way more user friendly than regular vector software like Inkscape/Affinity, because it give a much more direct controls on the shape objects. Of course it doesn't have any filling or stroke options, but that's obviously not needed for your CNC use.

I hope this helps.
