ORA-54502: solid not closed

Cause: The solid geometry was notclosed i.e., faces of solid are not 2-manifold

due to incorrectly defined, oriented, or traversed linesegment because each edge

of a solid must be traversed exactly twice, once in onedirection and once in the

reverse direction.

Action: Correct the orientation of theedges of the neighboring polygons.
