January 2026 monthly summary for FreeCAD/FreeCAD: Focused on stabilizing the Sketcher autoscale path. Delivered a code-level fix to prevent segmentation faults by adding a guard for specific constraint types in the autoscale workflow. The change was merged in PR #27077 (author amon-sha), commit 6a0d59b0c19aae0f38e390092b1627e8e36c839b. Impact: Increased stability of the Sketcher autoscale feature, reducing crashes and improving user experience for constraint-based scaling. This contributed to overall reliability in design workflows and lowered support overhead related to autoscale crashes. Technologies/skills demonstrated: debugging and defensive coding in the Sketcher module, Git-based collaboration and PR workflow, code review, and patching in C++/Qt-centric code paths used by Sketcher. Business value: Fewer crash reports, higher reliability for critical design operations, faster iteration cycles for users relying on autoscale, and a cleaner, more maintainable code path for future enhancements.
