Draft PathArray on a Part container fails

[Raph82]

Hello,

I just tested the Draft workbench PathArray function with a Part container. It does not show anything. If fails with this in the Report view:

Code: Select all

Running the Python command 'Draft_PathArray' failed:
Traceback (most recent call last):
  File "/usr/lib/freecad-daily/Mod/Draft/DraftTools.py", line 4772, in Activated
    self.proceed()
  File "/usr/lib/freecad-daily/Mod/Draft/DraftTools.py", line 4786, in proceed
    Draft.makePathArray(base,path,defCount,defXlate,defAlign,pathsubs)
  File "/usr/lib/freecad-daily/Mod/Draft/Draft.py", line 1254, in makePathArray
    if len(obj.Base.ViewObject.DiffuseColor) > 1:

'Gui.ViewProviderDocumentObject' object has no attribute 'DiffuseColor'

I've just started using PathArray, so I might be doing something wrong. My first try with a Part Cube did show the expected result though.

Does PathArray work with a Part container?
If it does, how do I make it work?
If it does not, any suggestions as to alternative workflows? Obviously I could use PathArray on individual parts. I was hoping to use it only once on a group of objects instead.
Also, should I submit a bug to the bugtracker?

Anyway, thanks for your time!

By the way, selecting multiple objects before the path then clicking on the PartArray icon does not produce an array of these objects along the path. Seems like one of the object is used as a path.

Looks like draft path array does not work with Part containers as the base.

As a workaround you can make a compound out of the individual objects and use it as the base for the path array.

Select the objects, from Part Workbench Part menu -> Compound -> make compound.
