are there any good free mechanical cad programs?
Draftsight is one (http://www.3ds.com/products/draftsight/overview/)
There is also CREO Elements
Inventor Fusion is currently free for a limited time, unless you have a MAC then there is no time restriction
I think Delcam offer free software as well.
thanks for the comments guys. i found a program called freecad 0.12. its free and i'm kindda fooling around with it. not enough good tutorials but the software is opensource and seems to have much more than sketchup.
please do look into it and give me some feed back.:) its got the potential to be big like solid works or solid edge.
i've used blender and i like it
free cad has a much more easier interface than blender and seems to be able to get the job done.
