TopologySegment
A TopologySegment is a distance in the Topology where no intermediate electrical contacts appear. If a Topology contains routed wires, then the wire at the beginning of a TopologySegment must be the same as in the ending.
TopologySegments are a logical construct to describe the physical representation of a wiring harness topology. Therefore, a TopologySegment is only valid if it has a physical manifestation. TopologySegments with a length of 0 or less do not have a physical manifestation and are therefore not valid.
Additionally, the usage of TopologySegments with a length of 0 create problems in the overall process. For example, the synchronization of 3D / 2D systems becomes harder or even impossible and the handling of wire protections on those TopologySegment is also unclear.

Attributes
| Name | Type | Mult. | Description | Owning Classifier |
|---|---|---|---|---|
| identification | String | 1 | Specifies a unique identification of the TopologySegment. The identification is guaranteed to be unique within the TopologySpecification. For all VEC-documents a TopologySegment-instance can be trusted to be the same if the TopologySpecification-instance is the same (see TopologySpecification) and the identification of the TopologySegment is the same. |
TopologySegment |
| form | SegmentForm | 0..1 | Specifies the form of the TopologySegment. A TopologySegment can either be circular or noncircular. |
TopologySegment |
| aliasId | AliasIdentification | 0..* | Specifies additional identifiers for the TopologySegment. Example: TopologySegment Ids may vary from one CAD system export to another. Therefore, the CAD system Id is improper for identification attribute. The identification shall have a value which is unique within the Topology. AliasId may be used for the CAD system Id. |

| processingInstruction | LocalizedString | 0..* | Specifies processing instructions for the TopologySegment. |
