Ok, here we go...
I've gone thru the pre-drill avi and saw a surface, (point cloud actually) being drug with the mouse around a point, changing the vortex of the surface where the drill goes in.. (ref. predrill_bmx.avi at about 75-80% from start). Very interesting for prototyping or customizing blends etc...
Also, the interface looks somewhat similar to Cimitron in function and navigation. (I've made some nice trodes with Cimitron, very capable and hard to learn software..) I can imagine the versitility just by looking at some of the menus displayed in the avi files and reading some of the doc files.
You've definately got my attention, but damn that learning curve.....get started I hope to have you trained in under a month..
