General Cam software

[Stephen Fornelius]

I'm using BobCAD/CAM for my 2.5D.  I sometimes import the DFX from Gearotic to BobCAD if I want to run a simulation or to get more options for milling.

I'm not recommending it because of the very poor tutorials.  The tech support is good, but it doubles the cost if you want tech support. 

I'm looking at FreeCAD now and comparing it to my copy of Alibre (which I think it pretty nifty if you learn to use it well).  Both of these are parametric, so its apples and apples comparison.
