I am preparing a course in Mechanical Engineering. I have been working as a teacher in Engineering. I have hand made notes. I am getting them typed on per page basis. This would help in preparing presentations and handouts for the course. But there are lot of diagrams. Could anyone suggest me a methodology to go about the diagrams, best software to draw them, or to use a pad and electronic pen to draw them live during the course video. Any tips and tricks for me for the process described above. Thanks.
