5.4.3.5 IfcAlignmentVertical
5.4.3.5.1 Semantic definition
An IfcAlignmentVertical is a height profile along the horizontal alignment. Points along a vertical alignment have two coordinate values. The first value is the distance along the horizontal alignment, the second value is the height according to the project engineering coordinate system. Based on the context of the project, they are georeferenced and the height value is convertible into orthogonal height above/below the vertical datum.

6 | ObjectPlacement | OPTIONAL IfcObjectPlacement |
This establishes the object coordinate system and placement of the product in space. The placement can either be absolute (relative to the world coordinate system), relative (relative to the object placement of another product), or constrained (e.g. relative to grid axes, or to a linear positioning element). The type of placement is determined by the various subtypes of IfcObjectPlacement. An object placement must be provided if a representation is present. |
7 | Representation | OPTIONAL IfcProductRepresentation |
Reference to the representations of the product, being either a representation (IfcProductRepresentation) or as a special case of a shape representation (IfcProductDefinitionShape). The product definition shape provides for multiple geometric representations of the shape property of the object within the same object coordinate system, defined by the object placement. |
ReferencedBy | SET [0:?] OF IfcRelAssignsToProduct FOR RelatingProduct |
Reference to the IfcRelAssignsToProduct relationship, by which other products, processes, controls, resources or actors (as subtypes of IfcObjectDefinition) can be related to this product. |
|
PositionedRelativeTo | SET [0:?] OF IfcRelPositions FOR RelatedProducts |
Reference to the IfcRelPositions relationship, which defines its relationship with a positioning element. |
|
ReferencedInStructures | SET [0:?] OF IfcRelReferencedInSpatialStructure FOR RelatedElements |
Reference to the objectified relationship IfcRelReferencedInSpatialStructure may be used to relate a product to one or more spatial structure elements in addition to the one in which it is primarily contained. |
