In Revit, a view template is a set of predefined display settings that can be applied to a view to control how the elements in the view are displayed. View templates can include settings for the visibility and display of elements, such as walls, floors, doors, windows, and MEP systems, as well as settings for the display of annotations, such as dimensions, text, and symbols.
View templates are useful for standardizing the appearance of views in a project and for controlling the level of detail that is shown in a view. They can be used to create different views for different purposes, such as construction documents, presentations, or analysis.
To create a view template in Revit, you can use the "View Templates" command from the "View" tab. You can then specify the display settings that you want to include in the template and give the template a name. View templates can be saved and reused as needed, and they can be applied to multiple views at once.
