View > Look At

Automatically centers the view on the picked objects, including construction planes.

Look At Options

Fit to View

If Fit to View is turned on, using Look at also dollies in on the object as it is centered in the window. By default, Fit to View is on.

When Fit to View is turned on, using Look at in the Perspective window moves the perspective camera.
When Fit to View is off, using Look at changes the view point but not the eye point.

Exclude Lights

If you use Look at when nothing is picked, the camera includes all objects in the view. If Exclude Lights is turned on, lights and textures are excluded.

Include Symmetric Objects

If this option is turned on (default), Look at takes into account the symmetric instances of objects (on layers with symmetry planes) when determining a new camera position.

Orient to Ground Plane

If this option is turned on, Look at re-orients the view to place the ground plane at the bottom of the screen. This option is off by default.

When a construction plane is selected in the Perspective window, the Look at tool orients the view flush to the plane (that is, the view vector becomes perpendicular to the plane).
