3D View Tools
Camera Menu
The Camera menu, located in the upper-left corner of the Canvas, lists the currently
active camera view. Choose from a list of reference cameras and scene cameras, as well
as several view-related commands.
The Camera menu is divided into three sections:
 The top section allows you to select the currently active camera as well as any other
scene cameras you have added to the project. If a scene contains more than one
camera, the camera that is topmost in the Layers list and in the Timeline at the
current frame is the active camera. For more information on scene cameras, see
“Cameras” on page 26.
 The middle section allows you to select one of the default reference cameras:
Perspective, Front, Back, Left, Right, Top, Bottom.
 The bottom section allows access to two commands: Reset View, which resets a
camera to its default view, and Frame Objects, which frames the selected objects in
the active view. If no objects are selected, Frame Objects resets the reference camera
to view all the objects in the scene.
