Abstract:

This paper proposed a new technology of constraint resolving based on parameterization of freeform feature model. In this method, parameterized freeform feature definition point, established geometry constraint graph, decomposed constraint problem into triangle constraint and tetrahedron constraint, and solved each of them, constructed sub-problem as global result by using handedness rule. This arithmetic was implemented in the HUST-CAIDS, and the result model can meet designer requirement.
