Hi Bill,

There is a list of CAM programs that support .3dm files on the Rhino resources page.
Whether that means you must export a model as an STL, I'm not sure.

Bill,
An excellent cam program called Madcam ( stands for mold and die) that works inside Rhino can work with any file you can get into Rhino. So any MOI .3dm file can be machined.

Hi:

Please Free Mill proves they say that it is free but I cannot make it him to work
