Angle About Y (AY)

Returns the rotational displacement (in radians) of one coordinate system marker about the y-axis of another.

Format

AY (To Marker, From Marker)

Arguments

 
To Marker
(Required) The coordinate system marker whose rotation is being measured.
From Marker
(Optional) The coordinate system marker with respect to which the rotation is being measured. If not specified, this argument defaults to the global coordinate system.

Equation

Mathematically, AY is calculated as follows:
where:
■ is the z-axis of To Marker.
■ is the z-axis of From Marker.
■ is the x-axis of From Marker.

Example

The following function returns the angle between the x-axes of marker_T and marker_F:
 
Function
AY(marker_T, marker_F)
Result
0.5235 or /6
