	XYZ^ normal
)

Parameters

right
Type: Autodesk.Revit.DB..::..XYZ
The specified vector.
normal
Type: Autodesk.Revit.DB..::..XYZ
The normal vector that defines the plane.

Return Value

The real number between 0 and 2*PI equal to the projected angle between the two vectors.

Remarks

The angle is projected onto the plane orthogonal to the specified normal vector, counterclockwise with the normal pointing upwards.
