Hi Matadem, so if you set WriteAnalyticSurfaces=y inside moi.ini then MoI should write out PLANE surfaces instead of B_SPLINE_SURFACE_WITH_KNOTS.

That's what I did to make the attached version.

Does this file behave better when you load it into FreeCAD?

Ok it is showing some toolpaths so I am going in the right direction with the file you provided.

I am running some more tests tomorrow.

Thanks!

Ok it works!
So I am going to play with it some more and do some test cuts....

I always think that Freecad could be a better program if it wasn't free lol.
I always follow its progress...

Thanks!
