CAD package for wiring diagrams

[eSteve]

Does anyone know of a good piece of software for drawing wiring diagrams?

I realise it could be done with any CAD package or SketchUp but would like to remove the tedium of drawing switches, fuses etc and have the package to have these items available within it so I can concentrate on the layout and function.

Any ideas?

Open source preferred.

PS Don't be thinking I've made an enormous leap in progress, and I'm on the wiring now, just thinking ahead, whilst I continue welding.

PPS: Just found a thing called SmartDraw which says it is good for automotive wiring diagrams, anyone used it? Just realised it's only free for 30 days

There must be some piece of software out there where i can type in headlights x 2, starter motor , indicators, fuse box etc etc, and it just draws me a wiring diagram.

No, oh, pen and paper then.

Or you could save a lot of effort and use this one: http://westfield-world.com/img/Wiring3.gif

I like saving time and effort thanks Enoch, that'll give me some thing to study

i use ms excel.. Use the connectors to be wires.. Very versatile.. You still have to draw switches but that doesnt take long

Thanks for your replies.

Yes, tex, sometimes using something simple is the best idea.

I did in the end find some software called ProfiCAD (free for non-commercial use) which was the sort of thing I was after. See: http://www.proficad.com/

There is a motor cycle wiring diagram in their gallery which has a lot of symbols on it appropriate for the Roadster.

But for now will study the Westfield diagram, and actually make some progress on the chassis.
