NX二次开发-UFUN提取面UF_MODL_extract_face获得面的面积UF_MODL_ask_mass_props_3d

• 版本

NX9+VS2012

• 说明

获得一个面的面积，有两种方法，一种是用UFUN函数，

先用UF_MODL_extract_face提取面，得到片体，然后再用UF_MODL_ask_mass_props_3d获得片体面积。

• 源代码

NX9+VS2012

#include <uf.h>
#include <uf_ui.h>
#include <uf_modl.h>


UF_initialize();

//提取面
tag_t face_tag = 39373;
tag_t sheet_body = NULL_TAG;
UF_MODL_extract_face(face_tag, 0, &sheet_body);

//获得面积
double  acc_val[11] = {0.01,0,0,0,0,0,0,0,0,0,0};
double mass_props[47];
double statistics[13];
UF_MODL_ask_mass_props_3d(&sheet_body, 1, 2, 3, 1.0, 1, acc_val, mass_props, statistics);

//打印
char SurfaceArea[256];
sprintf_s(SurfaceArea, "%f", mass_props[0]*100);//厘米和毫米单位换算
uc1601(SurfaceArea, 1);

UF_terminate();

另外一种方法就是录制NXOPEN，
