**Note:** There is a newer version of this specification see VEC 2.0.1

This section covers the general definition of a topology, the definition geometric views of that topology, placement of *OccurrenceOrUsages *on a topology and other geometric aspects like dimensioning.

All geometric coordinate systems used in the VEC are right-handed (Right-hand rule). This also means, the direction of the z-Axis is in the direction of the cross product (X-Axis x Y-Axis).
