Lately i tested FreeCAD and found an error in combination with Link and PartDesign.
For example: if you want do drawings with techdraw, you get issues with sections because occt can not detect faces correct, you can not do broken section and so on. Also you want separate the drawings from the part, because if you load an assembly, you wont laod the drawings (and also other thingsl like FEMs) too. So you make a link between the body from the part file and the drawing file. Then you must edit the bodies, for example a broken section. This works for Part, but not fro PartDesign.
If you want a linked body as BaseFeature, you get an error:
Code: Select all
<Exception> Object can only be in a single Group- 0.gif (361.01 KiB) Viewed 1050 times
An alternative could be a clone, but you also can not clone the linked body.

Here a screenshot from Part, which works.
