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

[Chris is me]

Recognize that learning to CAD and learning to design are two separate things.

Learn the basics of making solid shapes from extruding sketches, and mating assemblies. Then watch the entire 973 RAMP series (even if you use Inventor instead of Solidworks). Then CAD a simple robot for this build season.

Does any teams use Grabcad Workshop to help multiple people to work on the model at once? Does it work well?

I can't speak for what my team is dong this year but last year we used gradcad workshop fairly heavily. We worked on it by having each sub team CAD up parts and assemblies and then usually I or another teammate would add the parts to the (mostly) final overall model. This was done so there wasn't a ton a different versions of the main assembly. This kept most assemblies fairly up to date and accurate, and prevented people from uploading changes using an old version of the main assembly. It can work just make sure to be fairly careful to not change parts on an old version. Also we used version notes slot to keep track of what was done so we could track where changes came from. *Note we were using school issued computers (no install privalges) and out process involved downloading the models from grabcad and working on those then reuploading. We worked in inventor 2016. (On mobile right now so sorry if this isn't worded super clearly I can clear anything up if needed)

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.

Watch 973 RAMP videos.

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.
