【Abstract】 The constraint handling is very important in the parametric design system on the base of constraint. This paper mainly analyzes the fundamental conceptions, expressions, classifying specific properties of the constraint. Lastly this paper reports the course of extracting the solution of the parametric design system on the base of constraint.更多还原
