Entity Classes

Alignment (Alignment) Sealed EntityClass

Reference system to position elements mainly for linear construction works. Provides concrete implementation of an ILinearElement mix-in in the context of Road and Rail disciplines.

Base Class: BisCore:SpatialLocationElement

When an Alignment drives the design of a linear asset, it is referred to as a Design Alignment. Alignments used for design purposes shall be contained in a SpatialLocationModel, submodel of a DesignAlignments instance, and by default, shall use the Domain-ranked Alignment category.

On the other hand, when an Alignment describes a secondary entity of a linear asset, it is referred to as a Linear. Alignments created for the purpose of a Linear shall be contained in any SpatialModel, and by default, shall use the Domain-ranked Linear category.

An Alignment shall always have an associated HorizontalAlignment, but VerticalAlignments are optional. When an Alignment has one or more associated VerticalAlignments, it refers to the one used to describe its profile as being the Main Vertical.

The Alignment class inherits its LengthValue property from the ILinearElement mix-in. In the case of Alignments, such property shall store its horizontal length rather than its 3D length. Such horizontal length is computed from the associated HorizontalAlignment instance and cached into the LengthValue property of the Alignment.

An Alignment stores its visible geometry, typically a 3D approximation calculated as a stroked line-string, in its GeometryStream encoded as a Path.

Equivalent to IfcAlignment. The 3D approximation stored in its GeometryStream is equivalent to an IfcGradientCurve.

AlignmentStation (Alignment Station) Sealed EntityClass

Well-known location along a Linear-Element, with a specific Station value assigned to it.

Base Class: LinearReferencing:ReferentElement

AlignmentStations shall be used to map distances along from start measurements with station values along an Alignment, without forcing the use of relative linear-location measurements. That is, absolute measurements on or after the location of an AlignmentStation along an Alignment can still be mapped to station values at runtime without actually persisting them in the corresponding lr:DistanceExpression.DistanceAlongFromReferent attribute.

AlignmentStations are linearly-located elements along an Alignment. They shall carry the distance along measurement in a LinearlyReferencedAtLocation aspect whereas the mapped station value shall be stored in their Station property. Alignments shall define its initial station value in their StartStation property.

Equivalent to IfcReferent with a non-zero StartDistance attribute and relative measurements used by linear-locations referencing it.

Detailing of an Alignment horizontally (Top/Plan view).

Base Class: BisCore:SpatialLocationElement

A HorizontalAlignment typically has the same CodeValue and Category as its associated Alignment.

A HorizontalAlignment stores its visual geometry separately from geometry used for linear-referencing and design purposes, although the two could be identical. The former shall be stored in its GeometryStream whereas the latter shall be stored in the HorizontalGeometry property, encoded as a Path. Each curve primitive in such Path describes a segment along the HorizontalAlignment as follows:

The Z-coordinate of all of these primitives shall be zero.

Equivalent to IfcAlignment.Axis set to either an IfcGradientCurve (via its BaseCurve attribute), an IfcCompositeCurve or an IfcPolyline.

Individual segments along the HorizontalAlignment encoded as a Path are equivalent to IfcCompositeCurveSegments with the following Parent Curves:

  • Linear segments encoded as LineSegment3d are equivalent to IfcPolyline.
  • Circular arc segments encoded as Arc3d are equivalent to IfcTrimmedCurve based on an IfcCircle.

Every set of Alignments, contained in a SpatialModel, shall have one and only one instance of HorizontalAlignments leading to a Plan-projection SpatialLocationModel containing one HorizontalAlignment instance for each Alignment in the parent model.

Each HorizontalAlignments instance shall set its CodeValue property to "Horizontal Alignments", and by default, shall use the Domain-ranked Alignment category in the case of Design Alignments or the Linear category in the case of Linears.

VerticalAlignment (Vertical Alignment) EntityClass

Detailing of a Alignment or a portion of it, vertically along its path.

Base Class: BisCore:GeometricElement2d

A VerticalAlignment instance shall be contained in a VerticalAlignmentModel submodel of the Alignment instance it is associated with. Only one VerticalAlignment instance is considered being the Main Vertical for a given Alignment. Other VerticalAlignments associated with the same Alignment are typically used to describe the profile of assets designed along the same Alignment, e.g. the profile of the bottom of a Road ditch.

A VerticalAlignment by default use the Domain-ranked Vertical Alignment Category.

A VerticalAlignment stores its visual geometry separately from geometry used for linear-referencing and design purposes, although the two could be identical. The former shall be stored in its GeometryStream whereas the latter shall be stored in the VerticalGeometry property, encoded as a Path. Each curve primitive in such Path describes a segment along the VerticalAlignment as follows:

  • Linear segments shall be encoded as LineSegment3ds.
  • Circular arc segments shall be encoded as Arc3ds.
  • Transition segments (parabolic) shall be encoded as BSplineCurve3ds.

The X-coordinate of all of these primitives shall indicate distance along measurements in terms of the corresponding HorizontalAlignment. That is, an X-coordinate = 0.0 corresponds to the start location of its HorizontalAlignment. Y-coordinates shall indicate elevation at such location. Z-coordinate of all of these primitives shall be zero.

It is not uncommon for a VerticalAlignment instance to capture elevations only for a partial range of its corresponding HorizontalAlignment instance. Note that the opposite situation, a VerticalAlignment instance capturing elevations before or after the range of its corresponding HorizontalAlignment, while possible in theory is typically considered invalid in practice. This schema leaves the decision to validate against such case to particular implementations, however.

Equivalent to IfcAlignment.Axis set to an IfcGradientCurve (via its Segments attribute).

Individual segments along the VerticalAlignment encoded as a Path are equivalent to IfcCurveSegments.
