函数说明：
创建使用输入体内发生晋升的功能。推广特点是在工作中创建的。的发生必须是一个实心体发生从任一工作部分或其superassemblies之一。的发生也被用来确定哪个可能许多拷贝的该基地集固体推进。注：部分浏览器可能会留下过时了这个电话。需要调用UF_MODL_update进行更新。

函数参数：
第1个参数为输入：
body_occ代表参数变量，tag_t 为输入参数类型，身体发生的标签被提拔

第2个参数为输出：
feature_tag代表参数变量，tag_t * 为输出参数类型，新创建的促销功能的标签

UF_MODL_create_promotion函数实例代码演示：
在下面的例子中的代码的基部创建一个块并增加此基础部分的装配部分。随后，它发现身体发生在装配部分和推广。
