Errors when using assembly workbench #18

Closed EvanLF6768 closed 3 years ago

If trying to use this tool with an assembly workbench (eg. Assembly 3) always fails with:

Running the Python command 'CreateSimpleGroup' failed:
Traceback (most recent call last):
  File "/home/evan/.FreeCAD/Mod/ExplodedAssembly/EAInit.py", line 71, in Activated
    ea.createSimpleDisassemble()

    dir_vector = selection[-1].SubObjects[-1].normalAt(0, 0)

    plm = an_object.Placement

'NoneType' object has no attribute 'Placement'

This appears to be because selecting a face in an assembly selects the face inside the of the part hierarchy (eg. on a pad), instead of the face on the part itself.
