The best tool that I have found is the pro Help CD. When you install Pro E
this does not get installed. You have to install it separately and then
link it to your Pro E. I don't know if you are familiar with the old books
that PTC use to put out (Pro Model, Pro Drawing, Pro Surface etc etc.) they
were great. All that information is now on this CD. I make sure that
everyone that I work with has it on there computer. It will answer about
90% of your questions or at least give you a starting point.
Good Luck
