A strong feature of Revit is the ability to add view templates to views, to unilaterally change the settings on a view to make it look like another. Throughout the course of your project, you have probably set up several view templates for everything. Plans, Elevations, Enlarged plans, sections, etc all have a template associated with them. You can apply a view template as the default for the view, or separately from the view.
As you probably know a view template can be defined for a view one of two ways. First, you can assign it through the properties of the view under the setting 'default view template', or by right clicking on the view name in the project browser and assigning it that way. Unfortunately a big shortfall is that when you change settings of a view template it does not automatically re-define all views.
Say however that you are looking to apply the same view template as another view, but don't know exactly what template that view used. It is also possible for the 'default view template' field to show one thing, but a completely different template be applied to a view. In the 'apply view template' dialogue box, there is a checkbox under the list of views saying 'Show views'. Check this box and all the views will appear in the list (filtered by the type in the drop down box at the top). Simply find the other view you wish the current view to look like exactly, and select it and hit 'ok'!
