After selecting face of structure element, when user click on BentShape rebar button, it gives below error:

Running the Python command 'Arch_Rebar_BentShape' failed:

This error because of PyQt5. In PyQt5 orientation object has no addItems attribute. You may take help of other rebars to fix this.

This error because of PyQt5. In PyQt5 orientation object has no addItems attribute. You may take help of other rebars to fix this.

This issue has been fixed in commit https://github.com/SurajDadral/FreeCAD-Reinforcement/commit/d006c0aea3482b86efee1bb610e80f360addbcec

But there are still other errors, which I will try to fix.

@SurajDadral You probably also need to update in the BentShapeRebar.ui file. Change orientation to orientationValue.

@SurajDadral You probably also need to update in the BentShapeRebar.ui file. Change orientation to orientationValue.

BentShapeRebar.ui file already have orientationValue instead of orientation.

One more issue has been solved and now it seems that BentShapeRebar is working fine. Here is the PR: https://github.com/amrit3701/FreeCAD-Reinforcement/pull/11

One issue is still there: sketch.addGeometry(Part.LineSegment(points[1], points[2]), False) <class 'Part.OCCError'>: Both points are equal

And is also discussed on FreeCAD at: https://forum.freecadweb.org/viewtopic.php?t=22760&start=220#p186068
