During a two-month period, Marbo Cub contributed to the FreeCAD/FreeCAD repository by enhancing geometry compatibility and improving sketch constraint handling. He developed a backward compatibility layer for legacy tangent plane orientation, ensuring older documents remained functional while refactoring C++ and Python code for maintainability. His work included expanding regression test coverage to prevent future issues. In the Sketcher module, he addressed constraint robustness and standardized rotation normalization, resolving undefined constraint handling and improving stability for mirrored geometries. By combining algorithm design, geometry manipulation, and unit testing, Marbo delivered targeted fixes and sustainable improvements that deepened the reliability of FreeCAD’s core features.
