[ARX函数]：ads_xformss函数用法讨论

Hellow

1、R14的ARX中ads_xformss函数是否对于所有的实体均可进行变换?
2、实体镜像变换的矩阵形式是怎样的?

在ARX中，推荐你使用AcDbEntity::transformBy(....)

镜像矩阵，你可以用AcGeMatrix3d类的SET方法构造。

AcGeMatrix3d&
setToMirroring(

    const AcGePlane& pln);

pln        Input mirror plane

Sets this matrix to the matrix of mirroring with respect to the plane pln. Returns the reference to this matrix.

AcGeMatrix3d&
setToMirroring(

    const AcGeLine3d& line);

line        Input line of symmetry

Sets this matrix to the matrix of mirroring with respect to line line. Returns the reference to this matrix.

AcGeMatrix3d&
setToMirroring(

    const AcGePoint3d& pnt);

pnt        Input point of symmetry

Sets this matrix to the matrix of mirroring with respect to point pnt. Returns the reference to this matrix.
