This update brings big improvements to sketching and modeling, making Part3D smoother, faster, and more intuitive than ever. You can now create polygons, adjust circle and arc dimensions, and easily show or hide constraints, dimensions, and reference geometry while sketching. New context menus make it simpler to fix points or lines, toggle construction geometry, and fine-tune shapes directly on the canvas. We’ve also refined how sketching feels — dragging, selecting, and snapping are now more precise and responsive. Text and dimension visuals are clearer, and performance has been optimized for faster editing. Finally, this version improves reliability and fixes several small issues, full changelog below. New Features - Added Polygon tool for creating and editing multi-sided shapes. (Public Preview) - Introduced Arc Radius and Circle Radius dimension tools for clearer geometric control. - New Constraint Manager for more powerful and consistent constraint handling. - Added context menus for points, lines, and circles — making editing quicker and more intuitive. - Added show/hide options for constraints, dimensions, reference geometry, and plane preview. - Introduced construction geometry toggles and fixed point/line options directly in the sketch tools. Improvements - Unified gesture handling for dragging, selecting, and hovering in 2D sketches — smoother and more predictable interactions. - Optimized state management across tools and rendering layers, reducing lag and improving responsiveness. - Streamlined circle, line, and point tools with cleaner logic and consistent snapping. - Improved edge rendering performance by batching draw calls for better frame rates. - Refined text alignment, offsets, and scaling in dimension labels for more accurate placement. Fixes - Resolved crash on newer iOS versions - Fixed issues with circle constraint handling, null reference errors, and incorrect hit detection. - Prevented accidental deletion of the origin point when cleaning up sketches. - Corrected z-index and import path inconsistencies affecting UI layering. - Improved handling of fixed constraints and drag interactions to prevent unintended movement.

New Features: - Added ability to clear selection when user taps in any empty space. - Added leave confirmation dialogs to handle unsaved changes with better UI feedback. - Added initial support for B-spline curves in the parser for existing shapes. Bug Fixes and more: - Improved Sketch Faces selection handler - Fixed extrude cut operation when no entities are selected. - Fixed crash issue when creating a sketch on a existing face with unsupported shape. - Improved layout consistency in the initial screen.

Added a dedicated Translate Gizmo with position tracking for precise movement. Unified translate, scale, and rotate under a new Transform API for consistency. Camera Enhancements Added a new orthographic camera mode with correct distance scaling. Improved camera controls with smoother movement and interaction. 3D Plane Preview Added Plane3D previews to help visualize sketch planes during creation. Integrated plane preview into Sketch Dialog and Editor UI. Fixes Improved multi-selection handling during transformations. Fixed rotation calculations to use radians and properly respect rotation axes. Enhanced caching and cleaned up rendering in solids for better performance. Disabled plane preview by default in the Sketch Editor for clarity.

- Project From Part Tool Implemented the Project From Part tool in the sketch environment to support projecting 3D part edges onto sketches. - Help & Learning Tools Added a Help button that directs you to a Youtube Playlist. - Fixes Enhanced GLB caching mechanism to prevent crashes and reduce redundant geometry loads.

Hotfix for broken operations.

This update brings powerful improvements across sketching, 3D modeling, and user interaction, continuing our focus on precision and ease of use. Sketch Trimming Upgraded: Trim arcs, circles, and lines with smarter intersection handling for cleaner edits. New Constraint Icons: Visual cues added for constraints like perpendicular, coincident, and point-on-arc to enhance clarity while sketching. Improved Selection Tools: Edges are now easier to tap and select, even in complex models. Refined Edge Display: Edges now appear above solids for better visibility during editing. Performance Enhancements: Faster rendering, smoother interaction, and improved camera controls for a more fluid experience. Export Improvements: Better handling of selected solids when exporting to external formats or Cura. UI Refresh: Streamlined interface with updated buttons, menus, and dialogs, removing unnecessary clutter and improving layout consistency. New Interaction Tools: Long-press support on dialogs, move then anywhere you want. Settings and Preferences: The app now remembers dialog positions and other UI customizations. New Sharing Options: Support for sharing files more easily and expanded export capabilities including STEP format. EXPERIMENTAL: We've added experimental support for importing STEP files — try it out with smaller models, as large files may cause crashes. Thank you for using our app! We’re working hard to make it better with every release.

Hotfix: Properly render material of solids when in Sketch Mode
