These options determine how the object reacts to moves, drags, nudges, rotations, and changes to the focus parameters.
Dragging either the light or focus control point will override any of the lock settings.
Lock location of Light / Focus
Determines which point remains fixed when reshaping the beam. When Throw or Plan Distance is locked, moving the beam will move both points together.
Lock Length of Height / Throw / Plan Distance
Determines how the relationship between light and focus points is maintained when the beam reshapes.
| Lock type | Heights | Throw | Plan Distance |
| Move | Light/Focus lock determines fixed point, and the beam reshapes, moving the non-fixed point | Both Light and Focus point move, maintaining beam shape | Both Light and Focus point move, maintaining beam shape |
| Rotate | Rotating affects the pan, keeping the fixed point constant | ||
| Throw | Light/Focus lock determines fixed point, and the x/y coordinates of the non-fixed point to adjust the new throw. | Light/Focus lock determines fixed point, and the beam reshapes to the new throw with the pan and tilt remaining constant. | Light/Focus lock determines fixed point, and the z height of the non-fixed point adjusts to the new throw. |
| Pan | Beam rotates around the locked point | ||
| Tilt / Angle to Face | Light/Focus lock determines fixed point, and the beam reshapes, maintaining hanging and focus heights | Light/Focus lock determines fixed point. Beam shape remains constant, maintaining the throw as it tilts and adjusting the non-fixed point. | The x/y locations of both the light and focus remain constant, with the z height of the non-fixed point adjusting to the new tilt. |
Use Cases
Determining how high to hang a light on a boom
Insert the beam at the focus point.
Move the Light control point to the boom location in plan.
Lock Focus and Plan Distance
Set the Angle to Face
Optionally, adjust the Hanging Height to a rounded dimension
Determining where to hang an FOH truss
Insert the beam at the focus point.
Lock Focus and Throw
Set the ideal Throw and Angle to Face parameters
Visualizing a diagonal wash from an existing position
Use the Draw Light to Focus mode to insert the beam, clicking first on the position and then the approximate focus
Lock Light and Heights
Nudge the beam to adjust the focus, fine tuning diagonal coverage
Lighting hanging scenery
Lock Light and Throw
Adjust the Tilt to change the height of the focus plane to the center of the scenic element
