Dec 1, 2025December 2025 — FreeCAD/FreeCAD: - Key feature delivered: Part Design Hole Task UI Improvements, including localization of hole thread combo items, and visibility enhancements for hole clearance (on hole type switch) and thread depth (when threading is enabled). - Major bugs fixed: (1) Solid feature removal integrity—ensured the next solid correctly references the previous base feature to maintain design integrity after a transform removal; (2) Wayland GUI stability—avoid grabMouse on Wayland where unsupported to prevent GUI instability. - Impact and accomplishments: strengthened design reliability and user experience in Part Design; improved cross-platform GUI stability and localization readiness; reduced risk of invalid features after edits. - Technologies/skills demonstrated: localization, UI/UX improvements, cross-platform GUI handling (Wayland vs non-Wayland), code hygiene with targeted fixes in PartDesign and GUI modules.

No major bug fixes were reported; the month delivered targeted UX and GUI refinements that streamline edge-based dress-ups and clarify user actions. Key outcomes include preventing final-model rendering during edge selection for dress-ups (fillets/chamfers), and renaming the 'Preview' button to 'Confirm Selection' along with removal of unused helper strings. These changes improve workflow efficiency, reduce errors during dress-up operations, and improve GUI clarity. Overall, these efforts enhance user productivity and product quality, with strong traceability through commits. Technologies/skills demonstrated include UX-driven design, GUI refactoring, and disciplined version control across the FreeCAD codebase.
