It's because of an access violation caused by trying to generate a cone surface out of a revoluted line. eg:

import Part V = App.Vector
apex = V(0.0, 0.0, -65.00000000000001) center = V(0.0, 0.0, -26.25) major = V(38.75, 0.0, 0.0) axis = V(0.0, 0.0, -1.0) line = Part.Line(apex, center + major).toShape() line.revolve(center, axis, 360.0)

According to Chris_G, line has to be created not with Part.Line but rather with Part.LineSegment.

Can freecad python interpreter be adjusted to recognize this an output recommended command instead of crashing ?

I've got a similar issue. FreeCad 0.20.1 crashes whenever I try to import the attached *.f3d file.

crash.log

f3d_files.zip The "Holder_v13.f3d" crashes freecad "Front_Rev_1_v9.f3d" doesn't crash freecad, but nothing gets converted.

@tomate44 do you mind weighing in again ?

It is a OCCT crash that seem to happen here : https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Part/App/TopoShape.cpp#L2579 I tried to put the crashing function into a try/catch block, without luck. A more skilled dev should have a look.
