Use this procedure to open a model space view.
When you create a model space view that is referenced to a callout, the model space view can be placed in the drawing in which the callout was placed, into an existing project view drawing, or in a new project view drawing.
Model space views are displayed and opened in the Views tab of the Project Navigator.
