It would be nice to be able to use the 4th axis to its full potential in a sense that right now it is locked by indexing or wrapped tool paths around cylinders. Odd shapes like a cam or other organic bodies can not be easily machined since the CAM will not place tool paths for odd shapes. In its current state I have to do 3d contours and change tool orientation multiple times to machine all the way around the 4th axis for non cylindrical parts.
