Quick Mill is great in ZW3D CAD/CAM, what I could expect more is the future enhancement after I'm using ZW3D 2012 for a few months, as what they promise, I did get the 2X turning with the Fanuc post processor, it works pretty good, their support guys are nice. I did use VX for a few years, it was not only the tool for me, it means more.
I don't think QM is slow in development, they are promising to have 64bit support, as well as faster, safer and easier machining. I love their new CAM folder in ZW3D 2012, even though it needs a little more improvement. It shows me more confidence that QM is going to be better.
