面向与历史无关造型的三维约束求解方法研究

3D Geometric Constraint Solving for History-independent Modeling

摘要: 以基于历史的造型系统中应用较为成熟的两项技术--特征编码和二维约束求解为基础,基于特征进行三维约束建模,从而打破传统的基于历史造型系统中特征之间的单向依赖关系;然后将三维约束关系映射到二维草图进行处理,简化了问题.该方法在InteSolid 2.0上实现.

Abstract: An approach based on 2D geometric constraint solving and topological entity naming mechanism is presented to solve the geometric constraints between features in 3D space. An example is given to illustrate the process.
