Does anyone have any tips to Cad and design your first FRC robot?

Here is webinar my coworker created. He made the frame in one go for a 6 wheel West Coast tank drive. All you need to do after that is download the gearboxes and motors you want to use from AndyMark or VexPro.

After that, start with a drive train. decide on what type of drive you'd like (*cough*cough* 6 wheel tank). After deciding on six wheel tank drive, find another teams CAD from previous years. I'd Recommend 973 robots from previous years. Don't be afraid to borrow ideas from other teams in earlier years. As you likely know, FRC tends to repeat game pieces every few years (2012 and 2016).
This has saved my literal countless hours, before moving to CAD, start on paper. Sketching ideas on paper before moving on to a model will almost certainly help iron out a lot of kinks early on. That, and drafting is a timeless skill every designer should master eventually.
