During January 2025, this developer enhanced geometric accuracy in the IfcOpenShell repository by building a feature for precise projected length calculations along gradient curve segments. Using C++ and applying geometry processing and numerical methods, they refactored the curve_segment_evaluator to support circular segment subtended and end angles, while also implementing the i component for linear segment length calculations. Their work addressed issue #6006 and was committed under a7a9fcc73abd4fe344d47ecde1830ab16307044d, improving the reliability of x-axis projections across multiple segment types. This contribution laid a solid foundation for more accurate curve modeling and downstream analytics within the project.
