The CumulativeRotateAngle property specifies the cumulative rotation angle, during the dragging operation. The DeltaAngle property specifies the angle (in degrees) that has been rotated the layer/object, during the drag operation. The RotateAngleValid property specifies an expression that validates the rotation angle of the layer, during dragging operation. The RotateAngle property specifies the current angle of the rotation of the specified layer. The Clockwise property indicates if the rotation is clockwise or anticlockwise. A clockwise (typically abbreviated as CW) motion is one that proceeds in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top.
