A spot elevation displays the actual elevation of a selected point. Use spot elevations to obtain points of elevation for ramps, roads, toposurfaces, and stair landings.
You can place spot elevations on non-horizontal surfaces and non-planar edges. You can place them in plan, elevation, and 3D views.
Spot elevations can also display the top and/or bottom elevation of elements with a thickness. Top and bottom elevations are available for elements in plan views.
