Note: There is a newer version of this specification see VEC 2.1.0

Specifies the cross-section area of a segment. For the data exchange the cross-section area is used and not the diameter, because the diameter is only a valid measure for circular segments. For circular segments, the diameter and the cross-section area can be translated into each other without the loss of information. Attributes of the type SegmentCrossSectionArea normally have the multiplicity [0..*]. This means that such an attribute can have SegmentCrossSectionArea entries for different crossSectionAreaTypes and valueDeterminations. It must not have multiple entries with the same crossSectionAreaType and valueDetermination.

Specifies the value of the cross-section area of the segment.

valueDetermination ValueDetermination 1

Specifies the method for determination of the value.

crossSectionAreaType SegmentCrossSectionAreaType 0..1

Specifies the type of the cross-section area of the segment. Different types are for example needed to differentiate between the designed space of a segment and the required space (e.g. calculated from the wires going through the segment).

Attribute is defined as an OpenEnumeration.
