BINARY TREE ALGORITHM OF TWO DIMENSION DRAWING EXPRESSED BY CONSTRAINT NETWORK

A graphic network expression of 2dimensional 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．
