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 Series, design layer viewport.
Design Series products also include the ability to control the attribute display of sheet layer viewport objects based on the data in the attached record formats. This viewport data visualization provides amazing flexibility for displaying objects in viewports based on attached data values or data ranges.
Class overrides and data visualization cannot be used for a viewport at the same time.
