Abstract :
The implementation of an offset capability for planar curves and profiles in a solid modeler is discussed. A curve is assumed to have a continuous tangent vector, and a profile is defined to be a composite curve, possessing only positional continuity. Algorithms are presented for offsetting both entities. A practical design problem, the solution of which makes use of the offset capability, is presented.
