To look at and fill the view with all objects in a scene
- In a view panel, select
View > Frame All (or press the hotkey a).
You can also choose from the main menu, or press Shift+A, to frame all objects in all views.
- The camera moves to fill the camera’s view with all objects in the scene (including lights and cameras, if their icons are displayed in the view).
Note:
View fit may have problems with some joints, where it will zoom out too far.
Specify the percentage of the view that should be filled with the framed items
By default, this value is set at 95%. You can adjust this value to determine how closely the camera should zoom into the objects when framing selected or all objects. Adjust this default Fit factor value in the Preferences window (Windows > Settings/Preferences > Preferences), Settings sub-section, Cameras section.
