Note: There is a newer version of this specification see VEC 2.1.0

A Dimension defines a measurement for the distance between two Locations. An acceptable tolerance can be specified additionally. If the Locations are not located on adjacent topology-elements it is possible to specify a Path for the dimension along which the measurement must be taken.

The value for the Dimension is not specified as NumericalValue (which can define a Tolerance as well). This is because the "valueComponent" of the NumericalValue is mandatory. For Dimensions it shall be optional since there are scenarios where the dimension only specifies a Tolerance for a distance defined by the topology (segment length + placement information).

Name Type Mult. Description Owning Classifier
identification String 1

Specifies a unique identification of the Dimension. The identification is guaranteed to be unique within the containing PlacementSpecification.

valueComponent Double 0..1

Defines the value of the dimension. This value can be null, if it shall be calculated and only a tolerance shall be defined.

valueCalculated Boolean 0..1

Defines if the value of the Dimension was calculated (e.g. the sum of segment lengths in the topology) or if it was defined manually.
