Hello Everyone,
For IfcAlignment2DCantSegment such attributes are defined in IFC4X3 schema:
StartDistAlong : IfcLengthMeasure;
HorizontalLength : IfcPositiveLengthMeasure;
StartCantLeft : IfcLengthMeasure;
EndCantLeft : OPTIONAL IfcLengthMeasure;
StartCantRight : IfcLengthMeasure;
EndCantRight : OPTIONAL IfcLengthMeasure;
Is it possible to get any information/documentation about them?
StartDistAlong and HorizontalLength are obviously paremeters along Horizontal alignment, but what about others? I assume all those define parameters for kind of law for profile points transformation during segment (intuitively, this could look like change Y coordinate of profile points in 2D CS of profile as for example points with negative X (CantLeft) go down on value, points with positive X (CantRight) go up on value or something), but what exactly these attributes should be interpreted, and how they related (if related) with IfcAlignment2DCant.TrackGauge value?
Thanks,
Igor E.
