This call allows certain constructs to complete implicitely already available data
Specifically for IFC4.3 and higher calls using the instances of the following entities are supported:
IfcAlignment => in case business logic is defined and not geometricaly representation is available yet
the geometrical representation will be constructed on the fly, i.e.
an IfcCompositeCurve with IfcCurveSegment instances for the horizontal alignment
an IfcGradientCurve with IfcCurveSegment instances for the vertical alignment
an IfcSegmentedReferenceCurve with IfcCurveSegment instances for the cant alignment
IfcLinearPlacement => in case CartesianPosition is empty the internally calculated matrix will be
represented as an IfcAxis2Placement
