Panagiotis Papacharalampous contributed to the gramaziokohler/compas_timber repository by engineering advanced timber modeling and fabrication workflows. He refactored core geometry and data models, introducing features like group-based nesting, robust contour generation, and tolerance-aware cross-section comparison to improve modeling accuracy and data integrity. Leveraging Python and XML, he enhanced serialization, implemented backend-agnostic testing infrastructure, and modernized the API for maintainability and extensibility. His work included architectural improvements such as local coordinate systems, proxy patterns, and modular design, resulting in more reliable geometry processing and streamlined integration with downstream tooling. The depth of his contributions strengthened both performance and code quality.

Work History
January 2026
9 Commits • 4 Features
Jan 1, 2026January 2026 focused on delivering robust, high-performance timber engineering capabilities in gramaziokohler/compas_timber. Major work included performance-oriented contour generation improvements (refactoring FreeContour to leverage DualContour with polylines) and input type fixes for contour classes, delivering faster, more reliable contour processing for client projects. In data integrity and compatibility, we implemented tolerance-based cross-section comparisons in BeamStock, enhanced part identification with optional BTLxGenericPart names, and migrated element_data to NestedElementData for more consistent key mapping across Stock and tests. NestingResult tolerance handling was streamlined with accompanying tests to ensure compatibility with BeamStock and improved readability. A small but meaningful code-quality improvement removed an unused import in panel.py, reducing dependencies. These changes collectively increase reliability, speed, and data fidelity, enabling teams to process more scenarios with fewer regressions and better traceability.

Jan 1, 2025January 2025 performance summary for gramaziokohler/compas_timber: Delivered substantial API, integration, and stability improvements across the timber workflow. Key work spanned API exposure and design documentation, fabrication integration, geometry/tolerance enhancements, and code quality improvements, collectively increasing external integration reliability and maintainability. House Mortise functionality was initially implemented and visualized, but a subsequent PR split removed the house-specific implementation to align with updated design, enabling a cleaner architecture. Public API visibility fixes restored a complete surface for downstream tooling, and testing coverage for BTLxWriter was expanded to improve export reliability.

Dec 1, 2024For 2024-12, delivered substantial feature work and reliability improvements in gramaziokohler/compas_timber. Key features include planar halflaps system with planar halflap variants and visualization fixes, Lap Geometry Mesh to represent lap volume as a mesh, and the full tenon/mortise workflow with multiple refinements. A new BTLxWriter workflow with public API exposure (model_to_xml) was added, accompanied by tests. API and internal naming improvements (self.beams -> self.elements; check_geometry -> check_elements_compatibility) and refactors increased consistency and maintainability. Cross beam extension for L-TOPO, data GUIDs cleanup, and removal of tolerance tightened topology validation. QA improvements cover linting/formatting, unittest adjustments after attribute refactor, and expanded test scaffolding. Documentation and changelog entries were updated to reflect these changes. Overall impact: improved geometry accuracy, rendering performance, and developer experience, enabling faster design iteration and more robust topology checks.
