Hi,

When I try to use FastenersWB on the edge of a linked part, I get an error : PropertyLinkSub does not support external object

The complete error on the report is the following :

11:17:14  <Exception> PropertyLinkSub does not support external object
11:17:14  Running the Python command 'FSISO7380-1' failed:
Traceback (most recent call last):

    obj.addProperty("App::PropertyLinkSub", "baseObject", "Parameters", "Base object").baseObject = attachTo

PropertyLinkSub does not support external object

Does fastenerWB support link part ? Thank you in advance.

Never tried on linked objects, so it indeed might not support it

I can confirm that this is an issue with external linked parts, assuming that I have everything set up correctly. This is a fairly big part of working with assemblies in Assembly4, so if a fix is possible, it would be quite helpful to many trying to use fasteners in multi-file Assembly4 Models. Is there any possible fix/possible plan?

A pretty simple fix seems to just be to change over from using PropertyLinkSub to PropertyXLinkSub on line 40 of FastenerBase.py, and this solves issues with external files, but it doesn't position the parts properly, at least in Assembly 4, due to the local coordinate systems that are used for the positioning of parts.

I just made this change while using FreeCAD v0.19 and it also works while properly positioning the fasteners on the linked objects. I don't use Assembly 4 but this fix at least takes care of the issue for my simple case.

Edit: I take it back, the fastener gets positioned correctly so long as the object hasn't been transformed in the linked document. As soon as I move the linked object, the fastener places itself at the "old" location instead.
