[分享] 继续提供ARX开发实用的函数代码
充填你的函数库，函数如下：static AcGePoint3d midPoint(const AcGePoint3d& pt1, const AcGePoint3d& pt2);
static AcGePoint3d wcsToUcs(const AcGePoint3d& pt);
static AcGeVector3d wcsToUcs(const AcGeVector3d& vec);
static void wcsToUcs(AcGePoint3dArray& ptArray);
static void wcsToUcs(AcGePoint2dArray& ptArray);
static AcGePoint3d ucsToWcs(const AcGePoint3d& pt);
static AcGePoint2ducsToWcs(const AcGePoint2d& pt);
static AcGeVector3d ucsToWcs(const AcGeVector3d& vec);
static void ucsToWcs(AcGePoint3dArray& ptArray);
static void ucsToWcs(AcGePoint2dArray& ptArray);
static AcGePoint3d ecsToWcs(const AcGePoint3d& pt, const AcGeVector3d& entNormal);
static AcGeVector3d ecsToWcs(const AcGeVector3d& vec, const AcGeVector3d& entNormal);
static AcGePoint2d ucsToDcs(const AcGePoint3d& pt);
static AcGePoint3d dcsToUcs(const AcGePoint2d& pt);
