Example: Finding Voids
In this example, we create a topology rule to find holes between existing polygons.
A hole is considered to be a face that does not contain any reference to polygons.
An example topology of faces
Face 3 has no polygon within it, so is considered a hole
When you define topology rules, you include the classes used to build topology, and the pre-defined topological primitives in the system data store.
The Use Schema setting should be selected in the Context tab to list the classes of external data stores and the pre-defined topological primitives in the 1Integrate data store.
