IfcCurveSegment
I followed the "Is this page difficult to understand? Let us know!" link on https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/IfcCurveSegment.htm
I am having some trouble interpreting the statement
RefDirection is bound to the parametrization sense of the segment.
What does "bound to" mean here?
