【Abstract】 The assembly variable design modeling based on the general circle graph tree, and analyzes the technology of layer control and mechanism of solving of constraints in this modeling. It points out that the going through process of top down is the process of solving constraints. The sequence of solving constraints was discusiedo. In the end, it puts forward the modeling of variable table and method of realization of parts relations.更多还原
