1、装入部件0 x, Z0 B& ~0 [# [( Q) i5 L4 J
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；

% S, K1 A" M# M' l' Y+ c6 m T" t( ?$ u2、创建配合关系
6 ~' z( [5 s+ W; Q6 c- a1 ga．通过函数UF_ASSEM_init_mc()初始化约束；
& i7 u% m6 o) B3 L6 l% Mb．定义约束关系，即填写结构UF_ASSEM_constraint_s中信息；
, K( Q# s" K# [+ j9 E# Y- [# \! E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。/ G) X X! \9 w1 V2 Y( R; C
