|---|---|---|---|---|
| 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. |
