Shifts the projector to the left or right relative to the screen

Horiz. Offset Angle

Displays the angle of offset from the projector to the screen, measured side to side on the horizontal plane and based on the L/R Shift value

Horiz. Offset Perc.

Displays the angle of offset from the projector to the screen as a percentage

Point at screen center

When the projector has been shifted to the left or right, keeps the projector pointed at the center of the screen

Tilt

Sets the tilt of the projector, in degrees, relative to the horizontal plane

Place Based On

Sets the position of the projector either based on a fixed lens size or the projection distance

Proj. Distance (Straight)

When Distance is selected for the projector placement, enter a projector distance value or click and drag the projector control point to set the distance

Proj. Distance (Actual)

Specifies the distance in 3D from the projector to the screen

Lens

Select a standard fixed or zoom lens size, or choose Custom

Zoom Factor

For zoom or custom lenses, sets the lens zoom factor

Show projector zoom range

(Projector zoom Lens only)

Indicates the optimal distance from the screen where the projector can be placed, given the zoom range of the lens

Show cone zoom range

(Projector zoom Lens only)

Indicates the optimal screen size, given the cone zoom range of the lens

Vertical Position

Select the projector placement mode.

Screen Center: The center of the projector lens aligns with the screen center

Align to Top: The top of the projector body aligns with the top of the screen border

Align to Bottom: The bottom of the projector body aligns with the bottom of the screen border

Stand: Places the projector on a stand selected in Stand Model 

Floor: Places the projector on the active layer plane with the height of the screen specified by the Z height of the projector

Rigged: Places the projector at a height specified in Floor Height with the bottom of the projector at the Trim height

Mounted: Places the projector with a down tube length specified by Structure Trim and Drop Distance

Specific Shift: Shifts the projector relative to the screen center by the Vertical Shift distance, as measured from the center of the projector lens

Vertical Shift

For projectors on a stand or with a specific shift, specifies the distance between the floor (as set by the Floor Height) and the stand or projector (this allows stands or projectors to be placed on a plane shifted up or down from the screen)

Stand

Displays the name of the selected stand

Floor Height

Use the standard class, select a class from the list of classes present in the drawing, or create a new class. Select <Video Screen Class> to place the video screen element in the same class as the video screen.

Class Prefix: Specifies an optional default root class naming standard for all video screen parts; click Assign Default Classes With Prefix to begin all video screen class names with the prefix, so that they are sorted together.

Assign Default Classes With Prefix: Sets the class names for all video screen elements to the standard, using the Class Prefix if there is one.

Video screen elements: For each portion of the video screen, specifies the class name standard; the class names shown here are applied to the elements.

Update

Updates the object when changes have been made to the Object Info palette parameters

Load Information

A projector is considered a point load in Braceworks calculations, while the video screen is considered a distributed load; if the insertion point is on, or along, a rigging object, it is considered to be a load on that structure. Load information is used for Braceworks calculations and reports (Braceworks required).

Include in calculations

(Braceworks required)

Includes the projector or video screen in Braceworks calculations; deselect each one to exclude it from participating in structural calculations

Only Rear Projector or Front Projector Screen Type can be included in calculations.
