In order to describe a wiring harness, the abstract information of a topology must be enhanced with information about the concrete positions of components in the topology. For purposes of clarity the explanation of this concept is split into two diagrams. This diagram explains how Locations are defined onto the Topology. The next diagram shows how these locations can be used to define Placements of components and Dimensions.
The VEC defines two types of Locations: NodeLocations and SegmentLocations. A NodeLocation references one TopologyNode. A SegmentLocation defines a single point on a TopologySegment located between its startNode and endNode. To achieve this, a SegmentLocation references the relevant TopologySegment and specifies as anchor the start- or end node as well as the offset from that anchor.
Note: In contrast to KBL 2.3 and GEO the VEC locations on segments are expressed by anchor and offset and not through relative measurements. This enables ease of handling in case of segment-length changes.
