To Change the Display of an Overlapping Stair

Use this procedure to create an overlapping stair and set the display properties to view the overlapped section correctly. For this example, we will display all components of the stair above the overlap section outlined in red.

To set the stair display, the Plan Overlapping display representation needs to be turned on and specific components need to be set. For overlapping stairs, in addition to the usual up and down groups, four other groups of display components are available in Plan Overlapping.

Display representation group	Definition
“components” up (above overlap)	Stair components below the cut height that are above the overlap section
“components” down (above overlap)	Stair components above the cut height that are above the overlap section
“components” up (below overlap)	Stair components below the cut height that are below the overlap section
“components” down (below overlap)	Stair components above the cut height that are below the overlap section

1. Open the tool palette that you want to use, and select a stair tool.
