Electrical engineers are the busiest people on earth

Therefore, we designed Capital Electra X to let you accomplish more by doing less

Capital Electra X automagically wires your circuits when you place symbols onto your drawings, resulting in 3 times faster circuit completion.

Reuse your circuits with just drag and drop, and all symbols and wires will be intelligently renamed, saving you a ton of time.

Circuits can be saved onto your own stencils, so the entire team can reuse them for extreme productivity gains.
