| Abstract: | Parametric feature-based modelling is a new,fast modelling technique. The paper explores the theory and method of parametric feature modelling on the basis of developing feature modelling tool system (FMT). The main contents consist of the follows: (1 )The representative scheme of parametric feature-based modelling; (2 ) Establishing the 3D constraint equations ; (3)Fast solving of the constraint equations. In a word,a feasible way to carry out 3D parametric modelling is proposed. |
