I'd be very interested in doing an online version of this (my team is in NH). Were you thinking of doing it separately for teams that use different CAD packages, though?
We use SolidWorks but I know teams have access to a variety of other packages too.
Also, FWIW I've written some SolidWorks tutorials that are specifically geared toward FRC students. We used them this past year for training, but I hope to reformat them to make it easier to take them out of sequence. The first 3 are CAD-oriented and the last one is design / calculation oriented.
