Really never remember experiencing this. I know you can edit parts within the
context of an assembly with it creating external references, but does anyone know
of a way to mate a part that is inserted into one sub-assembly to another part that is
in the assembly next level assembly? Basically this part in the sub assembly would
be fully defined using mates that cross over into 2 assemblies.
I am thinking this is not possible, short of using distance mates and giving it the look
as though it is mated like I described.
But I thought I would throw it out to you guys for thoughts or to see if there is a way.
