基于约束的装配图参数化设计

Constraint-based Assembly Parametric Design

介绍在参数化零部件库的基础上,通过定义参数表达式形式的装配关系或约束,来实现装配图设计的参数化设计,在设计者对零部件或装配尺寸的参数作出修改后,可自动进行装配图调整,既能充分体现设计者的设计意图,又能快速地按照设计者意图自动生成装配图,达到零部件参数化和装配设计参数化的统一。

This paper describes an assembly parametric design systems based on parametric component library by defining assembly relations in algebraic equations form. When designer modifies the parameters of parts or assmbly, assembly drawing will be adjusted automatically in terms of the designer's intention.
