I am in the process of buying Solidworks 2013 software, and I have a question about available engineering databases or libraries. My question is:

Are there ready made engineering designs databases or online libraries available in the market that I can register to or subscribe to and download Solidworks designs? If so, would you send me their names and how much they would cost?

I am running a machining and fabrication factory, and I need designs for overhead cranes, tanks, vessels, heat exchangers, etc.

Please help.
