Your electrical project, in phase.

FaseCAD is free software for electrical schematics. Parts, terminals, cables and reports all come from one project model, so the schematic and the documentation never fall out of phase.

90%

less time on your electrical schematics

Ask your AI assistant to draw, review or change your electrical schematics: projects are readable XML and FaseCAD runs from the command line.

Why FaseCAD

Start sooner, no strings attached, with your AI

  • Project templates. Save any part of a schematic as a template and reuse it in your next project. Ships with examples: direct-on-line start, star-delta start, and digital and analog I/O cards.
  • Open source. GPL licence: free forever, with no paid edition and no locked features. You can read and change the code.
  • Easy to connect to your AI. Projects are saved as readable XML and the program also runs from the command line, so your AI assistant can read, review and edit schematics without closed plugins or extra licences.
