Use the Options menu > Show Bounding Plane command to toggle the bounding plane feature on and off.
When this feature is active, a cyan line appears in some views showing you the location of the active plan or elevation view. For example, if a plan view is active and a three-dimensional view is also showing, the cyan bounding plane appears in the three-dimensional view around the story level associated with the plan view. As a second example, if an elevation (or developed elevation) view is active and a plan view is also showing, the cyan line appears in the plan view showing the location of the elevation.
The table below lists the circumstances where the bounding plane (line) appears.
