For CAD training, Team 2530 created a series of CAD tutorials (we call "aCADemy") to help people learn Inventor, with particular emphasis on commands most likely to be used for designing robots. Here is a C.D. link: https://www.chiefdelphi.com/forums/s...d.php?t=131538
This year, we are migrating to OnShape (due to how CAD is administered in the school we are affiliated with), and are using their online tutorials to learn it. Depending on how time flies, we might create a tutorial for this, too.
