Technical drawing and sketches for physics and engineering?

Theoretiker

Hello,

I am searching a programm for technical drawing and skteches in physics and engineering. It should be able to draw in 2-d and 3-d, should have more than only a few funtions and freeware, best if it works with the GPL.

Does such a programm exists for free? The Operating System isn't very important. My favor would be for Leopard mac osx but Linux or even Windows would be well also.

I learned Auto-cad in the University but this program is only avaible in the faculty for using and a home edition of auto cad would cost more than I have...

thanks :)

Linux has a couple of CAD type programs out there, as for Mac OSX, not a clue.

Oh, okay. I am working with Linux but I have a small distribution. Could you give me a few names?

google linux, cad and kde (one of the front-ends), you'll find a mitt full.
