Can't create new bend/junction
Describe your issue
I was not able to add new bends to an already created body that already had some bends added. I was able to edit the existing bends but not add a new ones. I tried with a blank file ant the error persists. Tried using old FreeCAD (0.21.2) - still no go.
To test and reproduce I renamed my FC user folder (as fresh start as possible), installed SheetMetal WB, created new file, switched to SheetMetal WB, added new base shape, selected a straight edge (right internal edge of the wider section) and tried to create new bend. This is the error I get:
16:42:24 pyException: Traceback (most recent call last): File "C:\Users\Wivern\AppData\Roaming\FreeCAD\Mod\sheetmetal\.\SheetMetalBend.py", line 138, in execute s = smSolidBend( ^^^^^^^^^^^^ File "C:\Users\Wivern\AppData\Roaming\FreeCAD\Mod\sheetmetal\.\SheetMetalBend.py", line 107, in smSolidBend return resultSolid ^^^^^^^^^^^ <class 'UnboundLocalError'>: cannot access local variable 'resultSolid' where it is not associated with a value 16:42:24 SolidBend: cannot access local variable 'resultSolid' where it is not associated with a value 16:42:40 pyException: Traceback (most recent call last): File "C:\Users\Wivern\AppData\Roaming\FreeCAD\Mod\sheetmetal\.\SheetMetalBend.py", line 138, in execute s = smSolidBend( ^^^^^^^^^^^^ File "C:\Users\Wivern\AppData\Roaming\FreeCAD\Mod\sheetmetal\.\SheetMetalBend.py", line 107, in smSolidBend return resultSolid ^^^^^^^^^^^ <class 'UnboundLocalError'>: cannot access local variable 'resultSolid' where it is not associated with a value 16:42:40 SolidBend: cannot access local variable 'resultSolid' where it is not associated with a value 16:42:49 pyException: Traceback (most recent call last): File "C:\Users\Wivern\AppData\Roaming\FreeCAD\Mod\sheetmetal\.\SheetMetalBend.py", line 138, in execute s = smSolidBend( ^^^^^^^^^^^^ File "C:\Users\Wivern\AppData\Roaming\FreeCAD\Mod\sheetmetal\.\SheetMetalBend.py", line 107, in smSolidBend return resultSolid ^^^^^^^^^^^ <class 'UnboundLocalError'>: cannot access local variable 'resultSolid' where it is not associated with a value 16:42:49 SolidBend: cannot access local variable 'resultSolid' where it is not associated with a value
Despite the error FC lets me confirm the dialog but there is no proper resulting solid and the feature is in error state.

As I already explained this happens even with the default base shape from SheetMetal WB so here is a file with that, screenshots of the edge selected, resulting error when Make Bend is pressed, error message from report view:

@luzpaz It seems that attachments are missing after your edit ?!?
Seems indeed the files are missing The reason I asked for a sample is because I just cant reproduce it.
Oh! I get it! You are using the wrong function... the AddBend function turns a solid corner into a bend:
you should use this one:
It is as you said. My bad. I was wandering why there are so few options in the task panel :) This issue could be closed then. Maybe this can be better captured and more meaningful error message be displayed - "Can't make bend from selection" or something along those lines?
I definitely agree the error messages have room for improvements...
Thank you! Not sure relying on open issues is the best way to solve things, but I've been banging my head against this exact problem since yesterday 😀
I realise it's difficult to explain these things concisely. I wonder if some wording like "Convert to bend" or your "Turn solid corner into a bend" on the tooltip would help. I think that would've been enough for me to realise it wasn't what I was after and then hunt further and (hopefully) find the Make Wall option (I'd managed to forget that in a whole week since happily working on the first part of my design 🤦)
