Scales the object about the specified origin point. sx, sy, and sz are the scaling factors for the x, y, and z dimensions repectively.
[Visual Basic .NET] Public Sub Scale3D ( _ ByVal Origin As IPoint, _ ByVal sx As Double, _ ByVal sy As Double, _ ByVal sz As Double _ )
[C#] public void Scale3D ( IPoint Origin, double sx, double sy, double sz );
[C++]
HRESULT Scale3D(
IPoint* Origin,
double sx,
double sy,
double sz
);
[C++] Parameters Origin
Origin is a parameter of type IPoint* sx
sx is a parameter of type double sy
sy is a parameter of type double sz
sz is a parameter of type double
