I do 100% of the CAM for my fly fishing reel kits and reels in VCarvePro. I started with CamBam and needed a more robust production-capable solution. (DOn't get me wrong, CamBam is excellent for what it does). VCarvePro has literally saved me 100s of hours and has paid for itself many times over. I run it on Windows 7 in Fusion on my Mac. If I have a few quick part edits, I'll often make them in VCarvePro, but I usually do my CAD in Rhino.

cheers,
