View tags are the symbols that represent other views or drawings, such as elevations, callouts, and sections.
For example, in a floor plan, the following symbol indicates an elevation.
For more information about view tags, see View Tags for Sections, Elevations, and Callouts.
You can control whether these tags are visible in views based on design options. For example, if a section view applies only to Option 1, the section tag should not appear in a view that is dedicated to Option 2.
The visibility of a view tag is determined by a property called Visible in Option.
For example, if you create an elevation to display a particular design option, you may want to specify that its elevation tag is visible in a floor plan that is dedicated to the design option.
This property also controls what design options are visible in the view itself. See Check the Design Option Setting for a View. When you change the Visible in Option property for a view, the Design Option Visibility and Graphics Overrides for the view are updated to show the selected design option.
