使用UFUN进行UG NX二次开发： 装配设计技巧及步骤

1、装入部件
M5 u. O" z: g: P0 F- Q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；2 p: E+ z5 Q$ Z: s$ l v
/ D( K& R0 `7 b1 q% J N
2、创建配合关系
9 U4 M, \9 k! r& M8 Y% f( K! p) Ya．通过函数UF_ASSEM_init_mc()初始化约束；; o7 l' b, s, h( N- d! Y
b．定义约束关系，即填写结构UF_ASSEM_constraint_s中信息；. A0 j+ r4 X4 }0 e" M0 e6 T
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。
& n7 U: B& N/ H6 R6 o. I# A2 ~c．通过函数UF_ASSEM_solve_mc()求解约束；
7 w% t9 o* h; l6 l/ Q& e" D, Dd．通过函数UF_ASSEM_apply_mc_data将约束应用到装配体上；; j- _7 V, q0 E8 [
e．通过函数UF_MODL_update更新模型。
