| Abstract: | A graphic network expression of 2 dimensional drawing is discussed in this paper. The decomposition principle of the graphic network is proposed. Meanwhile, the graphic network is converted into a resolvable binary tree. During the converting process the dimensioning consistency and manufacturability are researched. The acceleration of graphic network decomposition is studied. This technology provides a rapid and simple way to parametric design. |
