上面的那個例子，有點小問題。修改后如下

NX9+VS2012

#include <uf.h>
#include <uf_csys.h>
#include <uf_mtx.h>
#include <uf_curve.h>


UF_initialize();

//初始化3*3矩陣
double x_vec[3] = {1.0, 0.0, 0.0};
double y_vec[3] = {0.0, 1.0, 0.0}; 
double mtx[9];
UF_MTX3_initialize(x_vec, y_vec, mtx);

//創建矩陣
tag_t MatrixTag = NULL_TAG;
UF_CSYS_create_matrix(mtx, &MatrixTag);

//創建坐標系
double csys_origin [3] = {10, 10, 10};
tag_t CsysTag = NULL_TAG;
UF_CSYS_create_csys(csys_origin, MatrixTag, &CsysTag);

double P1[3] = { 10, 10, 10};
//創建直線終點
double P2[3] = { P1[0]+ 100, P1[1], P1[2]};

//從絕對坐標系轉換到當前工作坐標系
int InputCsys = UF_CSYS_ROOT_WCS_COORDS;
int OutputCsys = UF_CSYS_WORK_COORDS;
double OutputPoint1[3];
double OutputPoint2[3];
UF_CSYS_map_point(InputCsys, P1, OutputCsys, OutputPoint1);
UF_CSYS_map_point(InputCsys, P2, OutputCsys, OutputPoint2);

//創建直線
UF_CURVE_line_t LineCoods;
LineCoods.start_point[0] = OutputPoint1[0];
LineCoods.start_point[1] = OutputPoint1[1];
LineCoods.start_point[2] = OutputPoint1[2];
LineCoods.end_point[0] = OutputPoint2[0];
LineCoods.end_point[1] = OutputPoint2[1];
LineCoods.end_point[2] = OutputPoint2[2];
tag_t LineTag = NULL_TAG;
UF_CURVE_create_line(&LineCoods, &LineTag);

UF_terminate();
