Navigate in viewports

Navigation is accomplished using a camera and target metaphor. The camera and target can be visualized with the Camera command.

The viewport title has some special functions for manipulating the viewport.

• Click the title to make the viewport active without disturbing the view.
• Drag the viewport title to move the viewport.
• Double-click the viewport title to maximize the viewport. Double-click again to restore the size to normal.

Viewport projection

Viewports can have one of three projections: parallel, perspective or two-point perspective.

Right mouse navigation works differently in the two viewport styles. In parallel views, right mouse dragging pans the view. In perspective views, right-mouse dragging rotates the view. In the usual four-viewport layout, there are three parallel viewports and one perspective viewport.

Parallel

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 space.

Perspective

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.

Viewport navigation

Rhino’s easy navigation helps you to visualize your model.

The simplest way to change the view is to drag the mouse with right button held down. This pans the view in parallel views and rotates the view in perspective views.

You can change your view in the middle of a command to see precisely where you want to select an object or choose a point.

Camera

Show, hide, or toggle the visibility of the viewport camera.

UndoView

Undo the last view change.

Pan and Rotate

Pan

Shift the location of the view camera and target parallel to the view plane.

RotateCamera

Rotate the view target around the camera.

RotateView

Rotate the view camera around the target.

TiltView

Rotate the view around the view axis.

Zoom

DollyZoom

Move the camera location and change the lens length at the same time.

Zoom

Move the viewport camera so the area defined by a window selection fills the viewport.

Zoom1To1Calibrate

Calibrate the screen for the Zoom command, 1To1 option.

ZoomLens

Adjust the lens length of the viewport camera in a perspective view.

ZoomNaked

Zoom to include all naked edges on selected objects with naked edges.

ZoomNonManifold

Zoom to include all non-manifold edges on selected objects with non-manifold edges.

Set a view

MoveTargetToObjects

Move the target to the center of selected objects.

NamedView

Manage the named views.

OneView

Sets the active construction plane according to the current view direction to accommodate single-window modeling.
