What is the best way to create toolpaths to mill a 3d solidworks object (or 2d - flat cuts)?

I seem to remember that when I first purchased Solidworks 7 years ago there was a free CAM program bundled with the software. I think it was a "light" version. I can't remember what it was called.

The reason I remember this is that I also purchased MasterCam for Solidworks at the same time (from a different vendor) and my Solidworks Value Added Reseller tried to convince me to use the bundled Cam software instead of buying MC4SW.

MC4SW runs inside of Solidworks. It's a full featured CAM program. When I bought it, it was not a "mature" program and many of the features of stand alone MasterCam were not available in MC4SW. They've made a lot of progress in getting MC4SW much closer to the stand alone version. One nice thing about MC4SW is that if you change your model geometry after putting toolpaths on, in most cases you can update your toolpaths by clicking one icon.

It's not cheap but if you need to do a lot of CAM programming it works well.
