Hi William,

I'm not an Elec guy to wisely advise on your question. However, i hope i can provide some links to them.

FYI, SE has a partner programme called the Voyager partner programme which consists of 3rd-party software houses to develop specific solutions that integrate with SE. You can browse SE website to obtain more information on that.

As for effectively generating and re-producing 2D electrical drawings in SE Draft, you may create your standard electrical drawings or symbol either for the 1st time in SE or read in from ACAD, and drag them into the edge bar. By doing so, you've saved the particular 2D sketch as a feature. The next time you need the same sketch, browse to the saved location and drag it out on the drawing board. Simple as that. Hope i helped in some way.
