Google Sketchup

[grapefruit]

I know there was a brief thread on this but I don't think anyone had really used it.
I used it last night to design a two part folded section box (similar to the Electro Harmonix Bass Balls etc.) with some holes on the top and back.

It's pretty easy to get to know.
It does dimensions.
For free It's perfect for this kind of thing. I was going to do a chicken scratch hand drawn diagram to give to the metal work people but this will look much better. I recommend it to anyone who needs to do simple 3D drawings. I was hoping you could do 2D drawings with it. Does anyone know of a good free 2D drawing program that does orthographic projection?

Cheers,
Stew.
