Description

Class

<DRM Perimeter Related Geometry Topology>

Superclass

<DRM Geometry Topology Hierarchy>

Example(s)

Consider a plat of a residential subdivision whose streets and driveways are represented using <DRM Polygon> instances organized by a <DRM Perimeter Related Geometry> instance. To represent the geometric topology of the subdivision, the <DRM Perimeter Related Geometry> instance has a <DRM Perimeter Related Geometry Topology> component that represents the set of all <DRM Geometry Topology> instances showing how the driveways of houses in the subdivision are connected to the streets of the subdivision.
