Mixins

ILinearElement (Linear-Element) Abstract Mixin

Mix-in to be supported by Element-subclasses meant to play the role of Linear-Elements.

Applies To: Element

A Linear-Element is a one-dimensional object that serves as the axis along which measurements are made.

Equivalent to IfcLinearPositioningElement.

Properties

Name Description Label Category Read Only Priority
StartValue Distance along value at the start of the Linear-Element, measured from an absolute zero. Start Value false 0
LengthValue Length measure value for the Linear-Element. Length false 0
LinearElementSource Source element providing this Linear-Element. Source false 0

ILinearElementSource (Linear-Element Source) Abstract Mixin

Mix-in to be supported by Element-subclasses meant to provide Linear-Elements.

Applies To: Element

ILinearLocationElement (Linear-Location Element) Abstract Mixin

Mix-in to be supported by Element-subclasses located along a Linear-Element provided by a Linear-Element-Source.

Base Class: LinearReferencing:ILinearlyLocated

Applies To: Element

ILinearlyLocated (Linearly-Located Element) Abstract Mixin

Base mix-in for Elements to be linearly-referenced along Linear-Elements.

Applies To: Element

Implementations of the ILinearlyLocated mix-in are equivalent to IfcLinearPlacement.

ILinearlyLocatedAttribution (Linearly-Located Attribution) Abstract Mixin

Mix-in to be supported by Element-subclasses representing properties whose value is located along a Linear-Element and only applies to a portion of a Linear-Element-Source.

Base Class: LinearReferencing:ILinearlyLocated

Applies To: Element

Properties

IReferent Abstract Mixin

Mix-in to be supported by Element-subclasses that can play the role of a Referent (known location along a Linear-Element).

Base Class: LinearReferencing:ILinearlyLocated

Applies To: Element

Equivalent to IfcReferent. Note that IfcReferent is an IfcLinearPositioningElement, thus references to it use the same IfcRelPositions.RelatingPositioningElement than references to IfcLinearPositioningElement. On the other hand, a lr:IReferent is referenced from either a lr:LinearlyReferencedAtLocation or lr:LinearlyReferencedFromToLocation multi-aspects via their corresponding navigation properties.

Properties

Name Description Type Extended Type

DistanceExpression StructClass

Core structure carrying linearly-referenced information.

The DistanceExpression structure allows measurements to be captured in absolute terms (with respect to the start of the Linear-Element) or relative to an lr:IReferent, or both.

The DistanceExpression structure is equivalent to IfcPointByDistanceExpression.

The LateralOffsetFromILinearElement and VerticalOffsetFromILinearElement values are assumed to be measured perpendicularly from the tangent on the Linear-Element calculated at the location indicated by DistanceAlongFromStart.

Values in the LateralOffsetFromILinearElement are assumed to be positive for lateral offsets to the right of the Linear-Element and negative for lateral offsets to its left, with respect to its direction from start.

Values in the VerticalOffsetFromILinearElement are assumed to be positive for vertical offsets above the Linear-Element and negative for vertical offsets below it.

These assumptions are equivalent to a IfcAxis2PlacementLinear with its Axis and RefDirection attributes describing a perpendicular to the tangent at the linear location of interest along the BasisCurve.

Properties

Name Description Label Category Read Only Priority
DistanceAlongFromStart Distance-along false 0
LateralOffsetFromILinearElement Lateral offset false 0
VerticalOffsetFromILinearElement Vertical offset false 0
DistanceAlongFromReferent Distance-along from Referent false 0

Note that IFC further requires an individual reference to the appropriate IfcCurve from each IfcPointByDistanceExpression via its BasisCurve attribute. In contrast, the LinearReferencing BIS schema considers such curves an implementation detail behind a concrete lr:ILinearElement realization in a particular domain, and therefore, it does not capture it.
