Im using the real thing, costs a lot but is a great bit of kit.

google sketchup seems to be well liked by most. Not sure if it will output dwg/dxf, but i'd be surprised if it didn't.

I use FreeCAD which has been great.

For 2D drawings DraftIT is superb. There is a free version which works very well. There are fairly cheap (<£100) paid upgrades which add a lot of useful functionality, including DXF/DWG exports.

I've used this for my F1 project here:

And my TC project (still in progress) here:

Ok so I now have installed both freecad and google sketchup

How DO I go about making a cube with specific measurements?

For free 2D CAD I use Draftsight ***CLICKY***

Made by the same folk who make Solidworks, and completely AutoCAD (so DWG & DXF) compatible.

I now use this for work (I work in engineering design) in preference to AutoCAD as it has all the functionality that I use in AutoCAD and none of the fluff that I never used...so it's perfect!

Doesn't do 3D though...and you'd just asked about making a cube...which is a 3D shape, are you really meaning a square?

If your really meaning a 3D shape, then you probably should be looking for 3D modelling...and getting that for free is not so easy! Sketchup probably your best bet.
