标题: 【求助】装配中的"MateV18.h"
请问有谁知道“MateV18.h"这个头文件是做什么用的，为什么我在UG version18中找不到？
这个头文件在清华书中（第137页，第5行）创建配合关系的一段程序中用到。

另外清华中中创建配合关系的这段程序中（从第137页到第140页），为什么没有用到"UF_ASSEM_init_mc([$ftf)"和"ftf.part_occurrence = to_part_occ]"这两行？
多谢多谢

你用的是UG 18？
你把这个头文件不要试试
UF_ASSEM_init_mc(&ftf)函数好像是nx才出现的

多谢回帖，
我用的是UG 18.
昨天晚上我发了一个帖子问关于“UF_ASSEM_mating_condition"的问题，也是您回的吧，多谢。我跟了一个帖子就是问您关于这个”UF_ASSEM_init_mc"的问题，在UG18下，不用这个API也可以吗？
我的程序编译链接都正常，但配合关系就是无法创建，UF_ASSEM_solve_mc返回值正常，但下一句UF_ASSEM_apply_mc_data的返回值就不为0了，怎么也想不通。
清华那本书中给的装配例子我也试了，也是同样的问题，请问您用过那个例子吗？

你用UF_get_fail_message（）这个函数跟踪一下，看看系统提示的错误是什么，要不你把整个代码发上来大家看看

我完全照抄清华那本书上的例子，代码如下：

请问你用于装配的是零件还是装配体？instance、occurrence、protype这几个概念自己琢磨一下，也许是这个原因

作者: cg0606 时间: 2004-8-11 15:47
这些概念对我来说确实比较糊涂，我再想想吧，多谢多谢
