If you got the model, you don't have to "make" it in Pro-E. You can just use them.
Most company provide 3D models in their website. Some provide format for many CAD programs. Some will only have STEP or IGE files. You can still use them. in Pro-E.
I found it very "interesting" that people will go to internet forum and ask very simple question then wait a few days for answers. At the same time they could have Google, Wiki the same thing in 5 min.
I'm not clear on your question but one source of models is the mcmaster online catalog; some parts have technical drawings and/or 3D models which you can import to ProE.
