I can't reproduce this. Can you please attach a sample file?

I have a similar error when I try to apply a constraint. In the above example I have created 2 parts in part design workbench. Then I made a 3rd file in which I created the assembly. I have linked the bodies of the parts (As and pasgat) to the assembly file and put them in the "parts" folder of the assembly. I have followed this tutorial (but with other parts): https://www.youtube.com/watch?v=Q6pbU2dVCfQ&ab_channel=JokoEngineeringhelp Now, when I try to add a constraint I get the error message. 07:56:42 Traceback (most recent call last): File "/tmp/.mount_FreeCAzXcduO/usr/Mod/asm3/freecad/asm3/assembly.py", line 333, in claimChildren return getattr(self.ViewObject.Object, 'Group', []) <class 'AttributeError'>: 'ViewProviderAsmConstraint' object has no attribute 'ViewObject'
