Not sure if everyone already knows about this but I thought I would share it for teams who don't have a resource to learn how to use CAD.
Solidprofessor.com offers tutorials on how to use solidworks, mastercam, autodesk and other pieces of engineering software.
I cannot speak to the quality of the tutorials as I have not looked at them yet but FRC teams can request a free license to access their website. I believe it is only 1 license per team. The link for FRC specific teams to apply is

Our team just submitted our information and we are waiting to receive our license and get our new students trained!
