Jun 1, 2025June 2025 monthly summary for FreeCAD/FreeCAD. Delivered two major feature initiatives with focused hardening and API improvements, enhancing user experience in sketching workflows and reducing maintenance burden for object management: - Sketcher Auto-scale Improvements: automatic scaling of sketch geometry and camera view when a new dimensional constraint is added, with configurable modes (always scale, never scale, or scale only when no visual scale indicator). Included robustness fixes for autoscale (ellipse scaling ordering and handling negative geometry IDs) and a dedicated origin handling fix. - Document Object Management API Refactor: refactored Document::addObject/removeObject to consolidate logic via private helpers and added new bitmask options for finer-grained control over object addition/removal.
