UF_MODL_ask_mass_props_3d

enmybh

我用UF_part_open打开一个prt文件,然后打算用UF_MODL_ask_mass_props_3d输出实体的质量.但是程序运行时出错.
好象是tag of the object is wrong or ....
请高手看一下,特别是UF_MODL_ask_mass_props_3d这一句的&part是否正确?

    tag_t part;
    UF_PART_load_status_t error_status;
    UF_PART_open (part_name,[$part,&error_status )]
