When I used to do projects for an electrical engineering company, the Project Manager of the company would let me create the electrical circuit diagrams based on the location, and needs of the people in the community where I was doing the project. Some features I would always use was transformers, and other electrical components using programs such as Pspice, Multisim, or sometimes AutoCad. However, when I started taking my capstone design class, I was responsible for designing the circuitry of my product. The fact that I had done this before helped me to get through it in an easier way and provide a better quality work.
Let me know what you think!
Sincerely,
Roberto Pineda.
