Hello
you can access the Global Reference Viewer when working on individual parts or assemblies only if you have a licence for Advanced Assembly Extension Module (AAX) of Pro/e.
If you have the Pro/e Online help installed then goto :
UsingAdditional Modules > Advanced Assembly Extension > Referencies and Dependencies > Using the Global Reference Viewer.
In proe 2001 the Global Reference Viewer allows you to investigate three types of references, or dependencies, in an assembly: feature references, relations references, and component references.
