NXOPEN C++问题求助
以下是使用多个平面创建拆分体, 创建后我想获取拆分后的所有实体,以下加粗代码①或者②处, 不加这些代码, 拆分体正常生成,加上①或者②, 都会报错,报错如图,哪位大神帮忙看看错在哪里?

我使用vector的时候里面存放的东西都是一个一个放的，不知道你这样一起放是否可以。另外你上面的代码bbodys就是容器，以经收集了实体了。 白色治愈之风 发表于 2026-5-6 08:18

①处与②处是两种方式获取实体方式,我先使用的②处,报错了,所以尝试使用①处, 结果也是报错,
如果删除了①和②, 拆分体是可以创建成功的,拆分样式详见下图,
我是用很多平面拆分一个实体, 拆分后想将拆分后的所有实体收集起来, 结果报错卡住了 2217231767 发表于 2026-5-6 10:52

拆分之后是直接去参变成体还是拆分之后仍然是特征 UF_OBJ_cycle_objs_in_part，也可以试试这个函数 分割体使用UF_MODL_split_body更简洁些，也有对用的切割体输出:lol 白色治愈之风 发表于 2026-5-6 12:08

好的, 我原想是根据拆分体直接获取拆分特征所产生的实体,
用你提供的ufun方式, 就得先获取拆分之前的所有体, 拆分后再获取所有体, 两者比较才能获取拆分特征所产生的实体:lol 不小明我们不约 发表于 2026-5-6 13:08

ufun这个函数试过, 每次只能用一个面拆分, 我是用好几百个面拆分, 就得循环拆分, 效率慢,所以改用NXOpen c++方式, 拆分倒是快了,但获取体卡住了:lol
