-
The lower left corner of each viewport displays the current orientation.
-
To choose a different orientation, click the View Orientation
(Heads-up View toolbar).
-
When you switch from multiple viewports back to a single viewport, the model displays the orientation of the active viewport. If you then switch back to multiple viewports, the orientations are the defaults again.
-
You can change the orientation or rotation of a model in any viewport independently as long as the viewports are not linked.
You can link orthogonal views. Non-orthogonal views (such as Isometric, Trimetric, etc. or custom orientations) are not linked.
To link orthogonal views:
Click Link Views
(Standard Views toolbar) or Window, Viewport, Link Views.
The
icon on the flyout View pop-up menu indicates linked viewports.
Functionality with linked views:
-
Zooming and panning are linked for all orthogonal views.
-
View rotation using the pointer is not available.
-
If you rotate a view out of its orthogonal orientation, the view is no longer linked.
-
If linked views is on and you rotate a view into orthogonal orientation, the view becomes linked.
