Dimension
Note: There is a newer version of this specification see VEC 2.1.0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 Numerical_value (which can define a Tolerance as well). This is because the "valueComponent" of the Numerical_value 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).

| 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. |
Dimension |
| 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. |
