Parameters
Transformer
Orientation Mode
Specifies the representation to use when setting point orientation. The following representations are supported:
- 2D Rotation: Sets orientation as a rotation around the Z-axis, in degrees CCW from the X-axis.
- Normal + Spin: Sets orientation as a unit vector (normal) indicating pitch and yaw, and an angle (spin), in degrees, indicating roll (right hand rule).
- Axis Angle: Sets orientation as a rotation, in degrees (right hand rule), around an axis of rotation specified by a unit vector.
- Azimuth + Altitude: Sets orientation in degrees CW from the positive Y-axis (azimuth), and degrees from the XY plane (altitude).
- Matrix: Sets orientation as a 3x3 rotation matrix.
- Quaternion: Sets orientation as a unit quaternion (versor).
- Euler Angles: Sets orientation as angles A, B, and Y, representing, in order, rotations around the Z-axis, X’-axis, and Z’’-axis (intrinsic rotations, right-hand rule).
- Tait Bryan Angles: Sets orientation as angles yaw, pitch, and roll, representing, in order, rotations around the Z-axis, Y’-axis, and X’’-axis (intrinsic rotations, right-hand rule).
- Remove Orientation: Removes orientation.

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
