Mar 1, 2025March 2025 – KittyCAD/modeling-app: Focused on UX polish, stability, and test coverage to reduce user friction and improve maintainability. Key features delivered include a near-fullscreen, centered Electron startup window for a better first-run experience. Major bug fixes improved interaction accuracy and reliability: panning now requires left-click, raycasting prioritizes line segments over axis lines, TypeScript compile errors were eliminated via executeAstMock, and UI warnings were reduced through initialization hardening. Additional improvements gate axis planes behind error-free runs, and end-to-end tests were added for the rectangle tool panning to guard navigation-only behavior. Overall impact: smoother onboarding, fewer runtime warnings, lower risk of regressions, and a stronger foundation for future development. Technologies showcased: Electron, TypeScript, 3D scene management, raycasting, KCL error handling, and automated testing.
