cnc 3D cut modeling

[chrish]

With respect to modeling we have never been able to create a feature that would simulate a custom cutter shape cutting along a trajectory.For a 2D cut youcan rotate a sketch about an axis orsweep a section about a trajectory but what about a 3D cut. Creating a feature that is both a rotating sketch moving along a 3D trajectory to simulate a true cutter path of a custom tool? Is there an extension to wildfire that would allow for such a feature to be created?<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />
