Worked on the BHoM_Engine repository to address a geometry issue affecting panel extrusion accuracy in 3D modeling workflows. Focused on refining the extrusion vector calculation within Geometry3D.cs by deriving vectors from the normal of the central planar surface, ensuring alignment with the local Z-axis. This targeted bug fix improved the geometric correctness of panel extrusions and reduced the potential for downstream misalignment and rework. The work demonstrated careful application of geometry principles and C# development skills, with a strong emphasis on code quality and maintainability. The contribution reflects a methodical approach to software development and geometric problem-solving.
