Rahul Jetti sir told us about Solidworks, where it is utilized and how to utilized. Rahul Jetti sir taught us how to design the solid parts of different machines or any small instrument to make the rough idea about how actually the parts of machines or instruments have to be arranged.
He also told us how to draw the sketch of different parts of the machine in a single plane and then made it in the 3D plane by applying different features in that software (like the sketch, excluded boss, swept boss,eexcluded cut, etc).
Also, he had given me the assignment to make the design model of hard disk and I had done it..
