NX二次开发中，其他一些有用函数的使用大全
7，裁剪片体

UF_MODL_create_trimmed_sheet(sel_sheet,edge_count,trim_objects,&projection_method,
0,1,point_coords,0.1,&gap_point_count,&gap_points,&feature_obj_eid);
}
8,offset偏移
char distance_str[] = {"10.0"};//偏移的距离
intnum_curves;

UF_CURVE_offset_distance_data_toffset_distance;
offset_distance.distance= distance_str;
offset_distance.rough_type=1;
UF_STRING_t input_string;
input_string.id=curve_id;//加入想要偏移的线
input_string.num=1; //偏移矢量方向数量
input_string.string=&string_count;//偏移线的数量
intstring_dir=UF_MODL_CURVE_START_FROM_END;
input_string.dir=&string_dir;

9,创建平面
UF_STRING_tgenerator;
UF_STRING_p_tge = &generator;
UF_MODL_init_string_list(ge);
UF_MODL_create_string_list(1,12,ge);
ge->string= 1;
ge->dir= 1;//指定线从开始到结束
ge->id= arc_id;//指定边界的id
doubletol;
tol =.001;//直线公差
tol = .5* (PI/180);//圆弧公差
tol =.02;//不起作用
UF_CALL(UF_MODL_create_bplane(ge,tol,&bplane));
10，选择
1），点选择
tag_t point_tag;
double point;

FTN(uf5374)(origin,pts,&pts,&plane_eid);
}
11，临时点，线

}
12,WCS与绝对坐标转换
voidcycs_wcs(double point[])
{
tag_twcs_id,matrix_id;
double matrix[ 9 ];
//wcs_origin:工作坐标系原点,vec:工作坐标系轴向量,point_origin:点到原点的矢量
double wcs_origin ,vec,point_origin;
//1，得到工作坐标系
UF_CSYS_ask_wcs(&wcs_id);
UF_CSYS_ask_csys_info(wcs_id,&matrix_id,wcs_origin);
UF_CSYS_ask_matrix_values(matrix_id,matrix);

char*material_msg="ALL selcted objects will be removed";
string_msg =material_msg;
UF_CALL(UF_UI_message_dialog("",
UF_UI_MESSAGE_WARNING,
&material_msg,
1,
TRUE,
&buttons,
res_mes ));
}
16，选择过滤

)
{
return(UF_UI_SEL_SUCCESS);
}
else
{
return(UF_UI_SEL_FAILURE);
}
}

tag_t object//现在鼠标所选物体ID
)
{
user_data *obj;
obj=(user_data*)client_data;
int find_face=true;//接受
char *string1;
string1=newchar;
string1=UF_TAG_ask_handle_of_tag(object);
