MatterCAD 2.2026.5 (May 8, 2026)

New Features

Redesigned Array Tool
- Single unified Array operation replaces the old Linear Array, Radial Array, and Advanced Array
- Linear mode: copies along a direction with optional rotation and progressive scale
- Radial mode: copies around a central axis with configurable radius, sweep angle, and arc or full-circle patterns
- Transform mode: step copies using a manual transform or a named sibling object’s transform
- Compounding rotation mode in Linear creates spirals, fans, and helices naturally
- Scale Affects Offset option for nautilus-shell and geometric-progression layouts
Library Favorites
- Star any library item to add it to a persistent Favorites folder
- Quickly access your most-used primitives, generators, and saved parts from one place

Align
- Stacked alignment is now a direct mode button instead of a dropdown option
- Added clearer Simple, Offset, and Stacked modes for lining up edges, adding precise gaps, and building ordered stacks
File Support
- Added support for WEBP image format in image-based operations
- Improved SVG file parsing for more reliable imports
Reliability
- Improved 3MF file loading speed and reliability
- Better tab restoration between sessions

Login and Cloud Library Access
- Login and Cloud Library access are restored after a backend server upgrade broke sign-in.
- MatterCAD now prompts you to sign in again when cloud access finds expired or invalid credentials.
Scene Tree Selection
- Fixed inconsistent selection behavior when choosing objects from the scene tree.
Help Navigation
- Fixed navigation issues in the bundled help and release documentation.
Library Right-Click
- Fixed right-click behavior in the library tree view.
Sheets
- Fixed a crash that could happen while working with sheets.

All-New Direct3D 11 Rendering Engine
- Complete migration from OpenGL to Direct3D 11 for dramatically better performance
- FXAA anti-aliasing for crisp, clean edges
- Dual depth peeling for correct order-independent transparency
- Hardware-accelerated bed shadows
- Improved object outlines and selection visuals
Object Transparency
- Set alpha/transparency on any individual object in the scene
- Per-face color meshes support alpha without color damage
Lock & Hide Objects
- Lock objects to prevent accidental selection or editing
- Hide objects to reduce visual clutter while working on specific parts
- Unhide All and Unlock All commands to quickly restore visibility
- Locked and hidden objects are correctly excluded from ray-based selection
Improved Boolean Subtract
- Multi-subtract operations are significantly more reliable and accurate

File Handling
- Projects now save as 3MF by default instead of STL, preserving colors, materials, and design history
- Enhanced drag-and-drop support for files and folders into the 3D view
Workflow
- Save As and Move dialogs remember your last folder location
- Expression fields now support pi, tau, e, and count
- Esc key performs undo in design editing contexts
- 3D controls remain visible when mouse leaves the scene
Performance & Stability
- Fixed startup crashes and recursive load issues
- Fixed lighting and mipmapping rendering bugs
- Improved library tree view updates
- Dynamic near/far plane calculations for better zoom behavior
- Upgraded to .NET 10

SVG File Support
- Full drag-and-drop support for SVG files
- Direct conversion from SVG graphics to 3D objects
- Seamless integration with existing CAD workflows
Advanced OBJ File Handling
- Support for loading materials from ZIP archives
- Enhanced OBJ file parsing and material handling
- Better support for complex 3D models with multiple materials
Enhanced Tab Management System
- Cloud library tabs now persist correctly - your work stays exactly where you left it
- Improved tab organization and navigation
- Automatic restoration of open tabs between sessions

Streamlined Interface
- Reorganized Recent menu for faster access
- Better visual feedback during long operations
- Improved application startup time and responsiveness
Reliability
- Fixed critical crashes in 3D scene interactions
- Resolved memory management issues
- Improved application stability across all platforms

The following features represent the foundation that MatterCAD builds upon from MatterControl’s heritage:

Added Hollow Feature
Added Polygon Reduce
Added Mesh Repair
Put in fully automatic support (legacy support) as an opption in additon to new manual support option
Added Support for gsSlicer (Experimental new slicing engine)
Fixed bugs

Improved ungrouping of mesh (splitting into multiple meshes)
- Discard degenerate faces
- Discard microscopic discrete features

Added search bar for application
Improved design tool bar
- Added grouping to some items
- Added dual align button
- Added Arrange All button
Nudge items on the bed with arrow keys
Downloads folder is sorted by date

UI improvements
- Faster updates in Cloud Library folders
- Restore UI on re-open
- Better Keyboard navigation support
New error detection and warning system
- More hardware errors handled
Design tools improvements and optimizations
- New Twist tools
- Improved Curve tool
- Improved Align

Versioning: Moving to a (version).(year).(month) version number. Easier to read and more informative.
New State-of-the-art Subtract, Combine and Intersection (Window only)
