How do I merge bodies of different assemblies into one?
Try this technique: http://help.solidworks.com/2012/English/solidworks/sldworks/creating_a_joined_part.htm
Thats where I started.
The parts I want to join are all the same part! from different replicas of the same subassembly.
First of all, fix the problem with Boss-Extrude3 in the part.
I would be surprised if parts from different sub-assys could be joined. If you were able to join them, which sub-assy would the result belong to?
A further complication is that they are Virtual Components. You may have to save the part as an external part first, and then move it into one sub-assy before being able to join them ... but if they are physically the same part, why would you want to "merge" (Join) them?
