Sections and Segments

A sector unit (SU) is the portion of one circuit level within one sector. Sector unit count describes the size of a labyrinth type’s circuit–sector structure and measures the orbital extent of circuit sections and flow segments, independently of physical distance.

In a uniaxial labyrinth, the single sector encompasses each full circuit level. In a multiaxial labyrinth, each circuit level is divided into multiple sector units, which may be traversed individually or in continuous portions of varying SU extent.

A circuit section is a continuous portion of the path within one circuit level, comprising one or more sector units. Direct axis crossings can connect units into longer sections. A section ends when the path changes level.

A flow segment comprises one or more circuit sections traversed continuously in the same orbital direction. A turning transition, an axis crossing with a level change greater than one, or arrival at a center, waypoint, or exterior node ends the segment.

A direct crossing continues both the section and the segment. At a spiral crossing (±1), the level change is small enough for orbital movement to be considered continuous flow, extending the segment across adjacent circuit levels.
