2、创建配合关系
j4 T( r0 {+ O) F |2 O6 Ya．通过函数UF_ASSEM_init_mc()初始化约束；& j& z6 x; b! E3 f
b．定义约束关系，即填写结构UF_ASSEM_constraint_s中信息；
9 A4 U9 v7 U5 D( T) [) |2 J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。. j* [$ e* ?( u s' c }
