函数说明：
团结两具尸体。UF_MODL_unite_bodies_with_retained_options荣誉的设置建模Preferences对话框中选择“从布尔人脸属性”，但UF_MODL_unite_bodies始终应用的显示属性目标身上新面孔。

函数参数：
第1个参数为输入：
target代表参数变量，tag_t 为输入参数类型，目标和由此产生的体

第2个参数为输入：
tool代表参数变量，tag_t 为输入参数类型，刀体

UF_MODL_unite_bodies函数实例代码演示：
描述该程序演示如何使用下面的UG/ Open API的程序：UF_MODL_unite_bodiesUF_MODL_subtract_bodiesUF_MODL_intersect_bodies项目描述下面的例子需要一个开放，空白部分。该代码创建一个体和汽缸。然后执行结合，相减，相交及这两个机构与之间的操作撤消在每个操作之间。
