About comparing structures graphically

You can compare two structures (BOMs) and view the results to identify differences. The BOMs can contain different types of objects, such as mechanical parts, electrical parts, routes, and connections. You can use the graphical comparison capability with released BOMs or with structures that are configured by effectivity.

You can compare an assembly with an assembly, a part with a part, or two revisions of the same assembly. If you compare two revisions of an assembly, Teamcenter identifies the following supersedure information:

Adds These are objects that are in the target assembly but not in the source assembly. They have been added to the assembly.
Cancels These are objects that are in the source assembly but not in the target assembly. They have been removed from the assembly.
Moves These are objects that are in different positions in the source assembly and target assembly. Any object whose transform matrix differs between the source and target is identified as repositioned.
Reshapes These are objects that have alternate representations between the source assembly and target assembly. Any object identified with a UG ALTREP note type is identified as reshaped.
Common These are objects that are in both the source assembly and target assembly.
