Perusing trough free 3D Cad software...

[Bullit]

Do to a need to build as knob with specific dimensions that doesn't exist in the market i went perusing to 3D Cad software.

I was surprised to see at least 2 good free ones:

Designspark -a free version of Spaceclaim

Intuitive and easy to use.


PTC Creo Elements Direct Modeling Express - a Free version of PTC Creo Direct Modeling.

This i didn't tested yet but from the videos seems also to be a good one.
