使用UFUN进行UG NX二次开发：装配设计技巧及步骤

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
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、创建配合关系
a．通过函数UF_ASSEM_init_mc()初始化约束；
b．定义约束关系，即填写结构UF_ASSEM_constraint_s中信息；
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。
c．通过函数UF_ASSEM_solve_mc()求解约束；
d．通过函数UF_ASSEM_apply_mc_data将约束应用到装配体上；
e．通过函数UF_MODL_update更新模型。
