Modeler

A set of machinable features, as implemented in the _1modeling system [3], was selected for our representation. The _1system was developed at the University of Utah, and allows a user to design using mechanical features and geometric construction techniques, render images using several techniques, interface with NC manufacturing equipment, drive the inspection of parts, etc. The selected feature set includes stock, profileSides, profilePockets, and holes. Holes are defined by location, diameter, depth, etc. Profile features, as implemented in _1, are defined by profile curves and other parameters, such as depth and fillet radii. _1profile curves are composed of arcs, lines, and splines, linked end to end. We have limited profile curves in our feature set to arcs and lines for simplicity.
