Is there an existing issue for this?

Problem description

When you try to select a work plane that is automatically referenced to a face, it generates the following error

I have just realized that the error comes from when I want to use a face of a volume generated by extrusion as a work plane, and not for example on a wall of the BIM tool

[gianlucafiore]

Another mistake I just detected is that when selecting several faces from one or more volumes obtained by means of an extruded plane, only the first selected face is illuminated, but the second one is not illuminated by holding ctrl. Pressed

But with the walls it does work

I cannot reproduce this. Can you add a demo file?

Looking at the error message (2nd image) this may be related to toponaming code.

I can't reproduce the problem, nor with the provided file or a clean new shape... But reading the error message, it seems to indicate an edge and a face were selected? Although that too shouldn't produce an error, but just indicate a message

Could you provide a precise step-by-step instruction on how to reproduce the error?

[gianlucafiore]

1- I create some volumes from planes (rectangles, polylines), extruded. And I also create a wall with some minimal complexity to compare

2- the first error registered is that I want to establish the personalized work plane on any face of said volumes and I get the error detailed above. Not happening like this when I select a plane of a wall type volume

3- the next error that I identify is when, in the volumes (generated from extruded planes) I want to select by pressing the ctrl key. several faces of the same or different volumes, or faces and edges, or several edges, etc. It does not do so, only the first selected face/edge/vertex and the following ones are illuminated, although it does show in the tree on the left that all the different objects are being selected.
while on the wall I can select all the faces, edges and vertices that I want

Okay I see now. I still don't get an error, though, but indeed doing this:

1. Create a Draft Rectangle
2. Extrude it using Part Extrude
3. Cannot place the working plane on any of its faces anymore (no error though, the WP gets placed on the current view for me)

The selection looks OK though (Gui.Selection.getSelectionEx()[0].SubElementNames returns correct things like [Face1]

Investigating more...

[yorikvanhavre]

The selection looks OK though (Gui.Selection.getSelectionEx()[0].SubElementNames returns correct things like [Face1]

Actually not always. Now I get (';Edge2;:G;XTR;:H210:7,F.Face2',)

>>> FreeCADGui.Selection.getSelectionEx("", 0)[0].SubElementNames
(';Edge2;:G;XTR;:H210:7,F.Face2',)
>>> FreeCADGui.Selection.getSelectionEx()[0].SubElementNames
('Face2',)

There is our culprit. The second argument being 0 means: TNP disabled. Needs to be 1

[Roy-043]

There is an underlying problem that needs to fixed as well I think. SubElementNames should not contain such a string. Maybe one of the toponaming devs can comment? @CalligaroV can you have a look?

There are other occurrences of FreeCADGui.Selection.getSelectionEx("", 0) in the Draft and BIM code that would need to be checked as well.

Indeed, in
BIM/ArchCutPlane.py
BIM/bimcommands/BimCutPlane.py
Draft/WorkingPlane.py
