Jun 1, 2025June 2025 – FreeCAD/FreeCAD TechDraw: Key features delivered include a robust dimension formatting overhaul (replacing snprintf with safer C++ strings and updating the format preview to use QString::asprintf) and a new snap-to-drag for detail view highlights with configurable user preferences. Major bug fixed: persistent storage of cosmetic vertex tags in TechDraw now saves/restores correctly, with accompanying refactor to improve code quality and address linter warnings. Overall impact: enhances reliability, safety, and UX in TechDraw, reduces risk of format-related defects, and improves maintainability. Technologies/skills demonstrated: C++ string handling, Qt (QString::asprintf), refactoring, persistence handling, UX refinements, and adherence to linting and code quality standards.
