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.
Design Suite products also include the ability to control the attribute display of sheet layer viewport objects based on object data. This data visualization view provides flexible display of objects in viewports based on data values or ranges.
