Abstract
The challenges that a designer faces in modelling shapes of arbitrary topology, are well supported by the so-called H-rep concept, which is based on the tangent plane continuous interpolation of an arbitrary network of intersecting curves. Until recently, making general design changes in stages of detailed design was not well supported. A simple and efficient method is proposed to overcome this limitation in the H-rep, acting on points positioned on the surface. An effective design tool has evolved that allows feature curves to be manipulated regardless of detail, without negative effects on other design features.
