Got error when importing wires from .STEP and exporting a face with no GUI

[mnpica]

I'm trying to import wires and BSplines from .STEP file to create a face object and export face object to .STEP file.



If I run script with GUI ,everything is fine.

Trying to run in console with FreeCAD 0.17, Libs: 0.17R13541 (Git),I got "Unknown C++ exception" error.

Code: Select all

  File "E:/workspace/testing/FreeCad/importFace.py", line 24, in export_step
    Draft.makeSketch(activeDoc.getObject(name), addTo=baseSketch)
  File "E:\workspace\testing\FreeCAD-0.17.13541.9948ee4-WIN-x64-portable\Mod\Draft\Draft.py", line 2834, in makeSketch
    nobj.addGeometry(DraftGeomUtils.orientEdge(newedge,norm,make_arc=True))
  File "E:\workspace\testing\FreeCAD-0.17.13541.9948ee4-WIN-x64-portable\Mod\Draft\DraftGeomUtils.py", line 572, in orientEdge
    edge.rotate(base, axis, angle)
Base.FreeCADError: Unknown C++ exception

I found this post https://forum.freecadweb.org/viewtopic.php?t=29436 ,edited DraftGeomUtils.py at line 566.

Code: Select all

    if angle:
        if axis == Vector (0.0, 0.0, 0.0):
            axis = Vector (0.0, 0.0, 1.0)
        edge.rotate(base, axis, angle)

And I got another error "Exception (Fri Jul 31 10:58:13 2020): Wire is not closed. "

If I run script with 0.18 version, there is no Unknown C++ exception but still exception.

Thank you for your time.
