Below is a great CAD curriculum created by Orion DeYoe of FRC 3005 RoboChargers which covers an introduction to Onshape and some general FRC concepts and build styles. It was created for use within their own team but can apply generally to anyone who is learning. To follow along with the discussion, check out the ChiefDelphi thread for the course.
