下冲头问题

exturded下冲头拉伸得到的是 uf_list_t ，后续操作上没有tag_t来的方便，
UF_MODL_create_extruded( objects, taper_angle, limit1,point, direction, sign_ex, &features );
改用UF_MODL_create_extrusion(generators,face_num,trim_data,tape_angle,limit1,offsets,region_point,false,true,dir,sign,&objects_e,&obj_cnt);
获得的objects_e，为tag_t
后面打孔采用三步走策略
UF_MODL_ask_feat_faces(*objects_e,&objects);
UF_MODL_ask_list_item(objects,2,&face_d2);
UF_MODL_create_simple_hole(origin2,direction1,&d2,"70","120",face_d2,face_t1,&hole_2);
UF_MODL_delete_list( &objects );
UF_free(objects_e);
