Can anyone recommend some electrical design software that would be a good choice to start learning to use? I would like to be able to draw floor plans with electrical symbols, 1 line diagrams and panel schedules. Would also like to know what the most popular design programs are from starter, middle of the road to top. It would be nice to be able to learn on a starter version and be able to graduate to a better version without having to relearn from the start how the software works. Any advice much appreciated!
