To Display the Default Orientation
When you first create a model, it appears in a default view orientation, such as isometric or trimetric. When you open a model, it is retrieved in the orientation in which it was last saved. You can change the default orientation by using the Orientation dialog box (View > Reorient) or the configuration option orientation.
To display the model in the standard orientation, do one of the following:
Click View > Standard Orientation
Click . The Saved Orientations list opens.
Click Default. The model reorients to the default view.
