For any Shaper Origin users out there, you can now natively export to SVG from within Shapr3D. There is even an option to save your sketches as polylines, which will help avoid the continuity issue with @Petrho describes above.
We haven’t yet added support for Shaper Origins colour encoding for cut types, but meanwhile you should be able to easily manage this on the device directly while cutting.
You can access this feature from version 4.9 and can read more about it here: SVG Export local alternative - #9 by Seb_Shapr3D
