This tab page, available only for Zone List Schemes, is active if you previously selected any Related Elements on the Properties and Parameters tab page (see above).
Zone listing is not restricted to the geometry of zones. It also involves the construction elements contained in zones, specifically the surrounding walls, columns, freestanding walls, doors, windows and other objects within Zone spaces.
The controls of the Related Elements page allow you to customize the settings by which the elements associated with a zone or multiple zones are calculated in the zone report. The element types to be considered in calculations are selected in the Properties & Parameters tab page.
The filters of the Related Elements tab page are identical to those of the Properties & Parameters tab page of Element type lists.
