Hi,
Thanks for joining! I'm Roger, a Product Manager on the GrabCAD Team, and I wanted to welcome you to the Community.
You can check out GrabCAD feed www.grabcad.com/home to find new models and read answers to some very interesting engineering topics. You can also ask CAD/engineering related questions www.grabcad.com/questions to find a solution to your problem. There are lots of very useful tutorials, too.
Let me know if you have any questions or feedback about using GrabCAD. I'd be happy to help.
