On my course I have to do a hell of a lot of drawings, which I guess would be easier and quicker to do on a CAD package, we have AutoCAD at uni but I don't find it very usefull for creating electrical drawings. For a start I have to draw all the symbols first, was wondering if anyone knew of a free package that could do this, and save me a lot of time messing with AutoCAD, or even worse with my pencil and ruler! Any help would be greatfully received.

Scroll down on the left until you get to "Graphics" and theres an option for "Drawing, CAD". Give some of them a try, they should be gree as they are on a freeware site

Oop,s didnt notice you wanted electrical, some of them might cover it though.

You could try getting your hands on a copy of Crocodile Clips. That's pretty good for fairly basic electronic CAD and is a realistic testing environment

Was hoping to find something with symbols already stored on it, rather than having to draw my own and save them as a block? Anyone used a package with symbols already drawn, going to need quite a few and possibly more than a couple of sheets, it's going to be part of my final year project.

Somthing like Visio would be good, I had a legal copy of crocodile clips once which came with a magazine, I am not sure what happened to it though.

You need to look for flow diagram software which has the electronic circuit symbols, some of them are likely to contain the american version of the symbols though which can differ slightly.

When you say electrical what do you mean? Electronic?

There's the school-type croc clips and livewire type things, which to be honest, aren't very good nor powerful. I personally use Proteus ISIS which is absolutely supurb but also very expensive. Your best bet is PSPICE student edition which is free and, as the name suggests, includes a SPICE simulator.

To be honest it's going to be a bit of both, I'll be using PSPICE for the Electronic element, but was looking for something more Electrical for the control and power elements of my FYP. I definately saw the engineers on my placement year use a certain package that allowed this, it'd update the diagram numbering etc.. should you insert more than one symbol of the same type etc.. The guy i worked with is on holiday now until Jan so i can't get hold of him to ask about it. All the symbol were to a certain standard too.

Any ideas guys?

We had Crocodile Clips at my secondary school. Great program - so many science lessons spent making the largest on-screen explosions possible in the chemistry bit. I think the electronics part was pretty good too.

Hi again and thanks for your replies,

I've found some free Electrical CAD software for Students, I just thought i'd let you lot know after your help. This software is free and quite impressive, aparently this company's software is used by AIRBUS?? Anyway, if any of you fancy a look here's the address.

Or go to http://www.ige-xao.co.uk and have a look on products.

Just thought i'd let you know!!

Does Visio actually test the circuit for you?
