Worked on enhancing geometric accuracy in the IfcOpenShell repository by developing a feature for precise projected length calculations along gradient curve segments. This involved supporting both circular segments with subtended and end angles, as well as linear segments using the i component of total length. The approach required refactoring the curve_segment_evaluator to handle multiple segment types, ensuring reliable x-axis projection for downstream analytics and modeling. Leveraging C++ development skills alongside expertise in geometry processing and numerical methods, the work addressed project issue #6006 and established a foundation for improved curve modeling accuracy in line with IfcOpenShell’s technical objectives.
