I am a sophomore student in Indian Institute Of Technology, doing mechanical engineering (Just introducing myself as this is my first post in this super-mesmerizing website) Well, we haven't yet started any CAD courses in college, and i will have to bunk a few classes tomorrow to attend a workshop on ANSYS. A week later, there is a workshop on solidworks. And for a long while i've only heard of this software called autocad. So i was wondering, what are all these softwares about? Which one should i concentrate on so that i can start designing some mechanical stuff? I can already do some pretty good coding for embedded systems, so lets say if i wanna design an RC plane (mounted with a camera would be cool) which is the best software i can use for that purpose?
