View

The View options manage view controls.

Pan

These options control keyboard pan behavior.

Screen fraction ___

When you pan with the keyboard, Rhino pans in steps. The pan step is defined as the screen fraction value multiplied by the smaller of the two viewport dimensions (height or width) in pixels.

Reverse keyboard action

By default, Rhino pans the camera in the direction of the arrow key you press. Select this check box to make Rhino pan the scene instead.

Right mouse button pan

Always pan parallel views

If the view is not looking straight at the construction plane, sets parallel viewports so they will not rotate.

Zoom

Scale factor ___

Defines the step size for zooming with a wheeled mouse or the Page Up and Page Down keys.

To reverse the default zoom direction of the mouse scroll wheel and the Page Up and Page Down keys, set this number higher than 1.

Reverse action

Reverses the default zoom direction of the mouse scroll wheel and the Page Up and Page Down keys.

Named views

Named views set CPlane

Restoring a named view causes the construction plane saved with that view to also restore.

Named views set projection

Restoring a named view causes the viewport projection saved with the view to also restore.

Rotate

These options control view rotation. Some options affect both keyboard and mouse rotation, some only the keyboard rotation.

Increment in divisions of a circle ___

When you rotate a view with the keyboard, Rhino rotates the view in steps. The default step is 1/60th of a circle, which equals six degrees.

Reverse keyboard action

Make Rhino rotate the scene instead of rotating the camera around the scene. Reversing the keyboard pan and keyboard rotation makes them in sync with the mouse controls.

Rotate around world axes

Makes the view rotate relative to the world axes. You can use the tilt keys to rotate the view around the view depth axis.

Rotate relative to view

Makes the view rotate relative to the view axes rather than the model x, y, and z axes.

Dynamic redraw

Frames per second ___

The number of frames per second Rhino will attempt to redraw when zooming or rotating a view.

When you pan, zoom, or rotate a view, the scene is redrawn dynamically. With large models, the dynamic redraw can be very slow.

By default, to make sure the feedback is reasonably fast, Rhino cancels the redraw if necessary. Use these options to control the speed and responsiveness of the views.

Viewport properties

Linked viewport

Enables real-time view synchronization. When a standard view is manipulated, the camera lens length of all parallel projection viewports are set to match the current viewport. See: SynchronizeViews.

Single-click maximize

Maximizes a viewport with a single click on the viewport title rather than a double-click.

Wrap cursor at viewport borders

Causes the cursor to wrap at viewport borders during view manipulations (pan, rotate).

When unchecked, the cursor does not wrap. Use this option for absolute pointing devices like Wacom tablets.

Default 35mm camera lens length ___

Sets the viewport camera lens length when the viewport projection is changed from parallel to perspective.
