Hello,

I am currently working on an assembly that features a couple of parts (a frame, siding, a countertop, and corner trim.) Some of these parts have external references to others in the assembly (both the siding and the countertop refer to the frame.) My design tree is displayed in the following image:

I tried making a new copy of the assembly using Pack and Go. Unfortunately the external references did not seem to update to new assembly, as indicated by the question marks listed in the new assembly's design tree:

Does anyone know what I'm doing wrong?
