Sets the ECS Rotation which defines the angle in the range 0 to 2PI radians between the OCS X-axis for the point based on the normal vector and the X-axis that will be used for displaying the point entity (DXF 50). A positive angle rotates clockwise. A negative angle rotates counterclockwise. The initial value is zero by default. 

The ECS Rotation is used when PDMODE is non-zero. This method does not convert to an equivalent angle and sets the specified angle value.
