The Viewport Properties panel manages viewport properties.

Three viewport pages (model viewports, page 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

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).

Camera

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.


Camera (1) and Target (2) shown with Camera command.
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

Distance to Target

The distance from the camera to the target. The target point is projected along the camera axis (the line between the camera and target).

Location
Place

To pick a location for the camera

Target

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

Location
Place

To pick a location for the target

Wallpaper

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 Browse to select an image file.

Show

Shows or hides the wallpaper.

Gray

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 page, 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

Sets 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

Sets 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

Opens 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

Locks 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
