I am new to SolidWorks and EPDM. I converted a Unigraphics assembly to Solidworks; SolidWorks kept the assembly structure. I saved the assembly file and all of the components into our Vault. When I go to the Bill Of Material tab, in EPDM, it only shows the top level assembly, not all of the lower level components. Do I have to build the assembly structure in EPDM?
