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.
