[Robotgroup] 3d cad program needed

[Gray Mack]

Looking for a free cad program that is easy to enter points and manipulate faces and objects.
The most important feature is to be able to create a 3d faceted sculpture and then do a graph paper like print out of all the polygons that make up the object so that when scaled and cut out of metal/wood/cardboard panels they fit together to form the object. I am not sure what the term is for this polygon pattern view is so don't know what to search for.
