PD can open Pro/e files, IGES, STEP, DXF and several other file formats. You can make parts and assemblies and drawings in PD, basic stuff with object/action functionality that's similar to SW. In PD assemblies, you can freely mix PD and Pro/e parts. It just added the ability to import surface models or models with surfaces in them ~ Pro/e, IGES, STEP, etc. File handling is good, all Windows GUI operation, and graphics are spectacular. They have a translucent view (like Pro/e hidden lines) that you need to see to believe. Plus, Pro/e just adopted PD's key combo for spin/pan/zoom. Now they work the same. It's the kind of software you wish would be bundled on every Dell computer sold and give everyone, kids included, an experience with solid modelling.
It also has features that are unavailable or undeveloped in Pro/e, like a pretty nice album feature that would be good for engineering notebooks, product catalogues or assembly instruction booklets.
The free download of the Express version comes with tutorials to get you started. It's worth trying out. And with completely painless installation, don't see what's to lose.
: Isn't ProDesktop what is left of ComputerVision?
No, CADDS5 is what is left of CV. Pro/DESKTOP was bought out by PTC in the middle
90s. It used to be called something else, don't remember the name, but not connected to CV.
