1、装入部件- X2 W) n, q0 i
通过函数UF_ASSEM_add_part_to_assembly()指定部件装入的位置 、姿态等信息,实现在装配体中装入一个部件功能;
8 Q5 C- d2 F$ I- _6 p M$ A' d5 x2 [8 Z7 C f: m9 I3 a @
2、创建配合关系& v! |, ^) \+ n$ j' [: M

装配中各部件间的配合关系是通过装配约束关系来实现的。装配约束是指一个部件到另一个部件的约束,将部件A配合到部件B上,则部件A称为主动件(from),部件B称为被动件(to),在约束求解过程中,被动件在装配空间中的位置固定,而主动件将变换姿态到满足装配约束位置上。组成配合关系的约束之间不能存在几何关系上的矛盾,也不能形成循环定义。 h3 ]% U0 v8 y" T$ B) D' d
