The Focus Lighting Devices command spreads, or "fans," the focus of a selection of lighting devices. Multiple fan types are available. You can independently fan the tilt and pan angles using slider controls, or enter angle values to make fine adjustments. These changes apply to the lighting devices’ starting pan and tilt angles. If needed, click Pick Focus to set a shared focus for all of the lights prior to fanning. To restore each device to its default focus position (with no pan or tilt applied), click Home Lighting Device.
A dynamic preview of the beam angle and centerline shows how each light will be focused when the dialog box closes. You can automatically create a focus point object for each lighting device.
Select the lighting devices.

Lighting device list |
Displays the selected lighting devices, sorted by channel number. If the channel numbers are equal (or unspecified), the list is sorted by device location, from left to right, in the drawing. The devices can also be sorted by Instrument Type, Position, or Purpose; click a column heading to sort in ascending or descending order. To re-order the devices manually, click in the # column and drag items to the desired location. |

Controls the fanning of tilt or pan angles across the lighting devices. The fanning depends on the Lighting device list order. None: No fanning is applied.
Center Fan: Starting from the middle, values fan out in opposite directions.
Linear Fan from End: Starting from the last device, values fan in the same direction.
Linear Fan from Start: Starting from the first device, values fan in the same direction.
Fan To Center: Starting from the first and last devices, values fan towards the center in the same direction.
Inverted Center Fan: Starting from the first and last devices, values fan towards the center in opposite directions.
