In outdoor and indoor databases, the corners of single objects can be modified. A list of
all corners can be reached by selecting an object, clicking with the right mouse button and
selecting Properties.Figure 1. Selected building in urban database with context menu.
Besides a few other information, the Object Properties dialog contains
a list with all corners of the wall or building. Double-clicking an entry in the list opens
a dialog which allows changing its three coordinates (x, y and z).

There are two limitations for changes to the coordinates. In indoor databases, the corners
must describe a planar flat if that is not the case all changes will be reverted. In
outdoor databases, a change to the z value of a corner will change the z value of all
corners. All corners of a building always have the same height.
