A STUDY OF 2-D VARIATIONAL DESIGN AND MODIFICATION OF TOPOLOGIC RELATION

Hou Rongtao; Liu Erli(Beijing University of Aeronautics and Astronautics)  
The keys involved with variational design are the establishment, solution, transmission, and the variational modification of constraints. This paper presents a method to establish a 2-D geometrically constrained model, and to realize the modification of topologic relation of geometric models. The method also has the unique feature of implementing the modification without having to rely on the process of drawing.
