SEMANTIC CONSTRAINT MODELER FOR 2D AND 3D GEOMETRY

Design changes for 2D & 3D geometry are the most important features in the process ofproduct design.Constraint modeling for variationl geometry based on geometric reasoning is one ofthe best approaches for this goal.However,it is difficult for the proposed systems to maintain orhandle the consistency and completeness of the constraint model of the design objects.To changethis situation,a semantic model and its control approach are presented,aiming at the integrationof the data,knowledge and method related to design objects.Aconstraint definition system for in-teractively defining the semantic model and a prototype modeler based on the semantic model arealso implemented to examine the idea which is extended to 3D geometric design too.
