Hi, when trying to export a .step file from FreeCAD 0.21.1 to urdf using this framework I get the following error:

12:35:50  Running the Python command 'UrdfExport' failed:
Traceback (most recent call last):
  File "/home/hiwi/.local/share/FreeCAD/Mod/freecad.cross/freecad/cross/ui/command_urdf_export.py", line 142, in Activated
    txt += et.tostring(xml).decode('utf-8')

    for elem in elem.iter():

'XmlForExport' object has no attribute 'iter'

I have exactly followed the installation guide. Any ideas on how to solve this issue? Thanks in advance!

Should be fixed with 0b4b64f.

Note that it's better to create a CROSS::Link and setting the Visual or Collision properties, so that the mesh files are generated by CROSS.
