If the structure type is a building, shaft, or excavation this tab will be displayed. The tab lists the boundary points of the top of the structure. For rectangular buildings and shafts there will be four points and for irregular buildings and excavations there will be a point for each vertex in the structure. If the structure has vertical sides the points will be the same as the base points. If a slope is specified in the Geometry tab, these points will be re-calculated by the program when the form is opened.
