Solidworks models

Hi!

I'm trying to design a CNC system with C beams on Solidworks. (I need to show it to my lab mates, and solidworks is the software we use in our lab.) However, I find no such kind of solidworks model on the internet, though it is listed in this forum. Could any one tell me where can I download any solidworks model for C beams? I really don't want to draw it by myself as there are so many parts.

Thanks!
