elecscape
When I was looking for some software to draw up the electrical plans for the house, I didn’t really find anything that scratched my itch. So, I fired up Inkscape, rolled my own symbols and drew the plans just the way I wanted them.
For those DIYers out there, you can re-use them (see licence info below) and I’ve included my plans to get you started.
