Attributes

Name Type Mult. Description Owning Classifier
identification String 1

Specifies a unique identification of the GeometrySegment. The identification is guaranteed to be unique within the corresponding BuildingBlockSpecification. Over all VEC-documents a GeometrySegment-instance can be trusted to be the same if the BuildingBlockSpecification-instance is the same (see BuildingBlockSpecification) and the identification of the GeometrySegment is the same.

GeometrySegment
aliasId AliasIdentification 0..*

Specifies additional identifiers for the GeometrySegment.

GeometrySegment
startVector CartesianVector3D 1

Specifies the start vector of the geometry segment. The start vector is a tangent to the segment at the start position.

GeometrySegment3D
endVector CartesianVector3D 1

Specifies the end vector of the geometry segment. The end vector is a tangent to the segment at the end position.
