Overriding viewport display
By default, a viewport displays its portion of the drawing and the objects it contains as they appear in the design layer; however, viewport display is very flexible for the purposes of presentation.
You may wish to have several viewports displaying the same contents, but in different ways, with certain classes or layers hidden, grayed, or changed. This can be done by overriding the layer or class properties for a sheet layer or, for the Design Suite, design layer viewport. Viewport styles may be used to apply certain combinations of settings to different viewports to help balance consistency with flexibility; see Viewport styles and Creating and editing viewport styles.
If a Design Suite product is installed, the following options are also available.
Hide specific viewport objects with the Visibility tool.
Apply a data visualization to the viewport to control the display of objects based on their data. Using specific data values or ranges, you can either change the object attributes or hide the objects.
Data visualizations take precedence over class viewport overrides; if there is no conflict between class overrides and data visualization settings, the class overrides display, but if there is a conflict, the data visualization settings are used instead. Data visualizations prevent layer viewport overrides from displaying. Turn off data visualizations in a viewport to display the override settings.
