The Viewport Properties panel manages viewport properties.
Three viewport pages (model viewports, layout viewports, and detail viewports) contain information and controls that are relative to that viewport.
Model viewport properties
Viewport
Title
The viewport title displays in the top left corner of a viewport.
See: Naming conventions in Rhino
Size
The viewport width and height in pixels.
Width
The viewport width in pixels.
Height
The viewport height in pixels.
Projection
Parallel
Sets the viewport to a parallel projection.
Parallel views are also called orthogonal views in some systems. In a parallel view, all the grid lines are parallel to each other, and identical objects look the same size, regardless of where they are in the view.
Perspective
Sets the viewport to a three-point perspective projection.
In a perspective view, grid lines converge to a vanishing point. This provides the illusion of depth in the viewport. Perspective projection makes objects farther away look smaller. All three directions converge to a point.
Two-point perspective
Sets the viewport to a two-point perspective projection. This means that the z direction will not converge to a vanishing point.
Parallel projection (left), 3-point perspective projection (center),
2-point perspective projection (right).
Locked
Disables view manipulations in the current viewport.
The camera is the x,y,z position of the viewpoint or eye point.
The target is the x,y,z position in space that is at the center of the viewport and about which the view rotates.
Each viewport has its own camera.
Lens Length
When the projection is set to perspective, you can change the lens length of the camera. A "normal" lens length for a 35 mm camera is 43 to 50 mm.
Rotation
Sets the rotation of the camera about the camera axis (the line between the camera and target).
X Location
The camera x location in world coordinates.
Y Location
The camera y location in world coordinates
Z Location
The camera z location in world coordinates
X Location
The target x location in world coordinates.
Y Location
The target y location in world coordinates
Z Location
The target z location in world coordinates
Place camera...
Pick a location in the viewport, or enter coordinates to place the viewport camera.
Place target...
Pick a location in the viewport, or enter coordinates to place the viewport target.
Place camera and target...
Pick two locations in the viewport, or enter two sets of coordinates to place the viewport camera and target.
Wallpaper is a bitmap that displays behind the grid in a viewport. It does not change when you zoom, pan, or rotate your view.
Filename
Displays the wallpaper file name.
Click Choose... to select an image file.
Show wallpaper
Shows or hides the wallpaper.
Show wallpaper as gray scale
Displays the wallpaper as a gray image rather than color.
Rhino stores the wallpaper bitmap image in the Rhino 3dm file.
Layout Viewport Properties
When the active viewport is a layout, a different set of options is available.
Layout
Title
The layout viewport name.
Layout Settings
Printer
Select the target printer from the list of configured printers.
Layout Width
Set the width of the paper as well as the width (x length) of the layout. If the paper size not support by the selected printer, the Printer setting will be disabled.
Layout Height
Set the height of the paper as well as the height (y length) of the layout. If the paper size not support by the selected printer, the Printer setting will be disabled.
Edit
Open the Modify Layout dialog box.
Detail viewport properties
When the active viewport is a detail, a different set of options is available.
Detail
Title
Locked
Lock the detail so the view cannot be panned or zoomed.
Projection
Scale
Sets the scale factor for the detail scaling.
Layout: Model
___ <units> on layout
___ <units> in model

Opens the Modify Layout dialog box.
