-OrcaSlicer — open-source C++17 3D slicer. wxWidgets GUI, CMake build system.
+## Project Structure & Module Organization
+OrcaSlicer’s C++17 sources live in `src/`, split by feature modules and platform adapters. User assets, icons, and printer presets are in `resources/`; translations stay in `localization/`. Tests sit in `tests/`, grouped by domain (`libslic3r/`, `sla_print/`, etc.) with fixtures under `tests/data/`. CMake helpers reside in `cmake/`, and longer references in `doc/` and `SoftFever_doc/`. Automation scripts belong in `scripts/` and `tools/`. Treat everything in `deps/` and `deps_src/` as vendored snapshots—do not modify without mirroring upstream tags.
 
-## Build Commands
+## Build, Test, and Development Commands
+Use out-of-source builds:
+- `cmake -S . -B build -DCMAKE_BUILD_TYPE=Release` configures dependencies and generates build files.
+- `cmake --build build --target OrcaSlicer --config Release` compiles the app; add `--parallel` to speed up.
+- `cmake --build build --target tests` then `ctest --test-dir build --output-on-failure` runs automated suites.
+Platform helpers such as `build_linux.sh`, `build_release_macos.sh`, and `build_release_vs2022.bat` wrap the same flow with toolchain flags. Use `build_release_macos.sh -sx` when reproducing macOS build issues, and `scripts/DockerBuild.sh` for reproducible container builds.
 
-```bash
-# macOS
-cmake --build build/arm64 --config RelWithDebInfo --target all --
+## Coding Style & Naming Conventions
+`.clang-format` enforces 4-space indents, a 140-column limit, aligned initializers, and brace wrapping for classes and functions. Run `clang-format -i <file>` before committing; the CMake `clang-format` target is available when LLVM tools are on your PATH. Prefer `CamelCase` for classes, `snake_case` for functions and locals, and `SCREAMING_CASE` for constants, matching conventions in `src/`. Keep headers self-contained and align include order with the IWYU pragmas.
 
-# Linux
-cmake --build build --config RelWithDebInfo --target all --
+## Testing Guidelines
+Unit tests rely on Catch2 (`tests/catch2/`). Name specs after the component under test—for example `tests/libslic3r/TestPlanarHole.cpp`—and tag long-running cases so `ctest -L fast` remains useful. Cover new algorithms with deterministic fixtures or sample G-code stored in `tests/data/`. Document manual printer validation or regression slicer checks in your PR when automated coverage is insufficient.
 
-# Windows (replace %build_type% with Debug/Release/RelWithDebInfo)
-cmake --build . --config %build_type% --target ALL_BUILD -- -m
-```
+## Commit & Pull Request Guidelines
+The history favors concise, sentence-style subject lines with optional issue references, e.g., `Fix grid lines origin for multiple plates (#10724)`. Squash fixups locally before opening a PR. Complete `.github/pull_request_template.md`, include reproduction steps or screenshots for UI changes, and mention impacted presets or translations. Link issues via `Closes #NNNN` when applicable, and call out dependency bumps or profile migrations for maintainer review.
 
-## Testing
-
-Catch2 framework. Tests in `tests/` directory.
-
-```bash
-cd build && ctest --output-on-failure           # all tests
-ctest --test-dir ./tests/libslic3r              # individual suite
-ctest --test-dir ./tests/fff_print
-```
-
-## Code Style
-
-- C++17, selective C++20. PascalCase classes, snake_case functions/variables
-- `#pragma once` for headers. Smart pointers and RAII preferred
-- Parallelization via TBB — be mindful of shared state
-
-## Key Entry Points
-
-- App startup: `src/OrcaSlicer.cpp`
-- Slicing pipeline: `src/libslic3r/Print.cpp`
-- All print/printer/material settings: `src/libslic3r/PrintConfig.cpp`
-- GUI: `src/slic3r/GUI/`
-- Core algorithms: `src/libslic3r/` (GCode/, Fill/, Support/, Geometry/, Format/, Arachne/)
-- Printer profiles: `resources/profiles/[manufacturer].json`
-
-## Critical Constraints
-
-- **Backward compatibility required** for .3mf project files and printer profiles
-- **Cross-platform** — all changes must work on Windows, macOS, and Linux
-- Profile/format changes need version migration handling
-- Dependencies built separately in `deps/build/`, then linked to main app
-
-## Code review focus areas
-
-- Changes must not cause regressions in existing functionality, defaults, profiles, or project compatibility.
-- Features gated by options must not affect existing behavior when those options are disabled.
-- Changes should follow the existing code style and architecture. Architectural changes should be justified in code comments and the PR description.
-- Add helper functions or utilities only when existing code cannot reasonably be reused. Avoid duplication.
-- Keep code concise and clear. Manually simplify AI generated bloated codes before review.
-- Include targeted tests or documented verification for behavior changes, especially in slicing logic, profiles, formats, and GUI defaults.
+## Security & Configuration Tips
+Follow `SECURITY.md` for vulnerability reporting. Keep API tokens and printer credentials out of tracked configs; use `sandboxes/` for experimental settings. When touching third-party code in `deps_src/`, record the upstream commit or release in your PR description and run the relevant platform build script to confirm integration.

+
+## Overview
+
+OrcaSlicer is an open-source 3D slicer application forked from Bambu Studio, built using C++ with wxWidgets for the GUI and CMake as the build system. The project uses a modular architecture with separate libraries for core slicing functionality, GUI components, and platform-specific code.
+
+## Build Commands
+
+### Building on Windows
+```bash
+# Build everything
+build_release_vs2022.bat
+
+# Build with debug symbols
+build_release_vs2022.bat debug
+
+# Build only dependencies
+build_release_vs2022.bat deps
+
+# Build only slicer (after deps are built)
+build_release_vs2022.bat slicer
+
+
+```
+
+### Building on macOS
+```bash
+# Build everything (dependencies and slicer)
+./build_release_macos.sh
+
+# Build only dependencies
+./build_release_macos.sh -d
+
+# Build only slicer (after deps are built)
+./build_release_macos.sh -s

+./build_linux.sh -u
+
+# Build dependencies and slicer
+./build_linux.sh -dsi
+
+# Build everything (alternative)
+./build_linux.sh -dsi
+
+# Individual options:
+./build_linux.sh -d    # dependencies only
+./build_linux.sh -s    # slicer only  
+./build_linux.sh -i    # build AppImage
+
+# Performance and debug options:
+./build_linux.sh -j N  # limit to N cores
+./build_linux.sh -1    # single core build
+./build_linux.sh -b    # Debug build
+./build_linux.sh -e    # RelWithDebInfo build
+./build_linux.sh -c    # clean build
+./build_linux.sh -r    # skip RAM/disk checks
+./build_linux.sh -l    # use Clang instead of GCC
+```
+
+### Build System
+- Uses CMake with minimum version 3.13 (maximum 3.31.x on Windows)
+- Primary build directory: `build/`
+- Dependencies are built in `deps/build/`
+- The build process is split into dependency building and main application building
+- Windows builds use Visual Studio generators
+- macOS builds use Xcode by default, Ninja with -x flag
+- Linux builds use Ninja generator
+
+### Testing
+Tests are located in the `tests/` directory and use the Catch2 testing framework. Test structure:
+- `tests/libslic3r/` - Core library tests (21 test files)

+
+## Architecture
+
+### Core Libraries
+- **libslic3r/**: Core slicing engine and algorithms (platform-independent)
+  - Main slicing logic, geometry processing, G-code generation
+  - Key classes: Print, PrintObject, Layer, GCode, Config
+  - Modular design with specialized subdirectories:
+    - `GCode/` - G-code generation, cooling, pressure equalization, thumbnails
+    - `Fill/` - Infill pattern implementations (gyroid, honeycomb, lightning, etc.)
+    - `Support/` - Tree supports and traditional support generation
+    - `Geometry/` - Advanced geometry operations, Voronoi diagrams, medial axis
+    - `Format/` - File I/O for 3MF, AMF, STL, OBJ, STEP formats
+    - `SLA/` - SLA-specific print processing and support generation
+    - `Arachne/` - Advanced wall generation using skeletal trapezoidation
+
+- **src/slic3r/**: Main application framework and GUI
+  - GUI application built with wxWidgets
+  - Integration between libslic3r core and user interface
+  - Located in `src/slic3r/GUI/` (not shown in this directory but exists)
+
+### Key Algorithmic Components
+- **Arachne Wall Generation**: Variable-width perimeter generation using skeletal trapezoidation
+- **Tree Supports**: Organic support generation algorithm  
+- **Lightning Infill**: Sparse infill optimization for internal structures
+- **Adaptive Slicing**: Variable layer height based on geometry
+- **Multi-material**: Multi-extruder and soluble support processing
+- **G-code Post-processing**: Cooling, fan control, pressure advance, conflict checking
+
+### File Format Support
+- **3MF/BBS_3MF**: Native format with extensions for multi-material and metadata
+- **STL**: Standard tessellation language for 3D models
+- **AMF**: Additive Manufacturing Format with color/material support  
+- **OBJ**: Wavefront OBJ with material definitions
+- **STEP**: CAD format support for precise geometry
+- **G-code**: Output format with extensive post-processing capabilities
+
+### External Dependencies
+- **Clipper2**: Advanced 2D polygon clipping and offsetting
+- **libigl**: Computational geometry library for mesh operations
+- **TBB**: Intel Threading Building Blocks for parallelization
+- **wxWidgets**: Cross-platform GUI framework
+- **OpenGL**: 3D graphics rendering and visualization
+- **CGAL**: Computational Geometry Algorithms Library (selective use)
+- **OpenVDB**: Volumetric data structures for advanced operations
+- **Eigen**: Linear algebra library for mathematical operations
+
+## File Organization
+
+### Resources and Configuration
+- `resources/profiles/` - Printer and material profiles organized by manufacturer
+- `resources/printers/` - Printer-specific configurations and G-code templates  
+- `resources/images/` - UI icons, logos, calibration images
+- `resources/calib/` - Calibration test patterns and data
+- `resources/handy_models/` - Built-in test models (benchy, calibration cubes)
+
+### Internationalization and Localization  
+- `localization/i18n/` - Source translation files (.pot, .po)
+- `resources/i18n/` - Runtime language resources
+- Translation managed via `scripts/run_gettext.sh` / `scripts/run_gettext.bat`
+
+### Platform-Specific Code
+- `src/libslic3r/Platform.cpp` - Platform abstractions and utilities
+- `src/libslic3r/MacUtils.mm` - macOS-specific utilities (Objective-C++)
+- Windows-specific build scripts and configurations
+- Linux distribution support scripts in `scripts/linux.d/`
+
+### Build and Development Tools
+- `cmake/modules/` - Custom CMake find modules and utilities
+- `scripts/` - Python utilities for profile generation and validation  
+- `tools/` - Windows build tools (gettext utilities)
+- `deps/` - External dependency build configurations
+
+## Development Workflow
+
+### Code Style and Standards
+- **C++17 standard** with selective C++20 features
+- **Naming conventions**: PascalCase for classes, snake_case for functions/variables
+- **Header guards**: Use `#pragma once` 
+- **Memory management**: Prefer smart pointers, RAII patterns
+- **Thread safety**: Use TBB for parallelization, be mindful of shared state
+
+### Common Development Tasks
+
+#### Adding New Print Settings
+1. Define setting in `PrintConfig.cpp` with proper bounds and defaults
+2. Add UI controls in appropriate GUI components  
+3. Update serialization in config save/load
+4. Add tooltips and help text for user guidance
+5. Test with different printer profiles
+
+#### Modifying Slicing Algorithms  
+1. Core algorithms live in `libslic3r/` subdirectories
+2. Performance-critical code should be profiled and optimized
+3. Consider multi-threading implications (TBB integration)
+4. Validate changes don't break existing profiles
+5. Add regression tests where appropriate
+
+#### GUI Development
+1. GUI code resides in `src/slic3r/GUI/` (not visible in current tree)
+2. Use existing wxWidgets patterns and custom controls
+3. Support both light and dark themes
+4. Consider DPI scaling on high-resolution displays
+5. Maintain cross-platform compatibility
+
+#### Adding Printer Support
+1. Create JSON profile in `resources/profiles/[manufacturer].json`
+2. Add printer-specific start/end G-code templates
+3. Configure build volume, capabilities, and material compatibility
+4. Test thoroughly with actual hardware when possible
+5. Follow existing profile structure and naming conventions
+
+### Dependencies and Build System
+- **CMake-based** with separate dependency building phase
+- **Dependencies** built once in `deps/build/`, then linked to main application  
+- **Cross-platform** considerations important for all changes
+- **Resource files** embedded at build time, platform-specific handling
+
+### Performance Considerations
+- **Slicing algorithms** are CPU-intensive, profile before optimizing
+- **Memory usage** can be substantial with complex models
+- **Multi-threading** extensively used via TBB
+- **File I/O** optimized for large 3MF files with embedded textures
+- **Real-time preview** requires efficient mesh processing
+
+## Important Development Notes
+
+### Codebase Navigation
+- Use search tools extensively - codebase has 500k+ lines
+- Key entry points: `src/OrcaSlicer.cpp` for application startup
+- Core slicing: `libslic3r/Print.cpp` orchestrates the slicing pipeline
+- Configuration: `PrintConfig.cpp` defines all print/printer/material settings
+
+### Compatibility and Stability
+- **Backward compatibility** maintained for project files and profiles
+- **Cross-platform** support essential (Windows/macOS/Linux)  
+- **File format** changes require careful version handling
+- **Profile migrations** needed when settings change significantly
+
+### Quality and Testing
+- **Regression testing** important due to algorithm complexity
+- **Performance benchmarks** help catch performance regressions
+- **Memory leak** detection important for long-running GUI application
+- **Cross-platform** testing required before releases

-## Some Background
+## Some background
 
-Open-source slicing has always been built on a tradition of collaboration and attribution. [Slic3r](https://github.com/Slic3r/Slic3r), created by Alessandro Ranellucci and the RepRap community, laid the foundation. [PrusaSlicer](https://github.com/prusa3d/PrusaSlicer) by Prusa Research built on Slic3r and acknowledged that heritage. [Bambu Studio](https://github.com/bambulab/BambuStudio) in turn forked from PrusaSlicer, and [SuperSlicer](https://github.com/supermerill/SuperSlicer) by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.
+OrcaSlicer was originally forked from Bambu Studio, it was previously known as BambuStudio-SoftFever.
 
-OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.

+  * It provides the two following main factorization classes:
+  * - class CholmodSupernodalLLT: a supernodal LLT Cholesky factorization.
+  * - class CholmodDecomposiiton: a general L(D)LT Cholesky factorization with automatic or explicit runtime selection of the underlying factorization method (supernodal or simplicial).
+  *
+  * For the sake of completeness, this module also propose the two following classes:
+  * - class CholmodSimplicialLLT
+  * - class CholmodSimplicialLDLT
+  * Note that these classes does not bring any particular advantage compared to the built-in
+  * SimplicialLLT and SimplicialLDLT factorization classes.
+  *
+  * \code
+  * #include <Eigen/CholmodSupport>
+  * \endcode
+  *
+  * In order to use this module, the cholmod headers must be accessible from the include paths, and your binary must be linked to the cholmod library and its dependencies.
+  * The dependencies depend on how cholmod has been compiled.
+  * For a cmake based project, you can use our FindCholmod.cmake module to help you in this task.

+/** 
+  * \defgroup OrderingMethods_Module OrderingMethods module
+  *
+  * This module is currently for internal use only
+  * 
+  * It defines various built-in and external ordering methods for sparse matrices. 
+  * They are typically used to reduce the number of elements during 
+  * the sparse matrix decomposition (LLT, LU, QR).
+  * Precisely, in a preprocessing step, a permutation matrix P is computed using 
+  * those ordering methods and applied to the columns of the matrix. 
+  * Using for instance the sparse Cholesky decomposition, it is expected that 
+  * the nonzeros elements in LLT(A*P) will be much smaller than that in LLT(A).
+  * 
+  * 
+  * Usage : 
+  * \code
+  * #include <Eigen/OrderingMethods>
+  * \endcode
+  * 
+  * A simple usage is as a template parameter in the sparse decomposition classes : 
+  * 
+  * \code 
+  * SparseLU<MatrixType, COLAMDOrdering<int> > solver;
+  * \endcode 
+  * 
+  * \code 
+  * SparseQR<MatrixType, COLAMDOrdering<int> > solver;
+  * \endcode
+  * 
+  * It is possible as well to call directly a particular ordering method for your own purpose, 
+  * \code 
+  * AMDOrdering<int> ordering;
+  * PermutationMatrix<Dynamic, Dynamic, int> perm;
+  * SparseMatrix<double> A; 
+  * //Fill the matrix ...
+  * 
+  * ordering(A, perm); // Call AMD
+  * \endcode
+  * 
+  * \note Some of these methods (like AMD or METIS), need the sparsity pattern 
+  * of the input matrix to be symmetric. When the matrix is structurally unsymmetric, 
+  * Eigen computes internally the pattern of \f$A^T*A\f$ before calling the method.
+  * If your matrix is already symmetric (at leat in structure), you can avoid that
+  * by calling the method with a SelfAdjointView type.
+  * 
+  * \code
+  *  // Call the ordering on the pattern of the lower triangular matrix A
+  * ordering(A.selfadjointView<Lower>(), perm);
+  * \endcode

+  *
+  * \class LLT
+  *
+  * \brief Standard Cholesky decomposition (LL^T) of a matrix and associated features
+  *
+  * \tparam _MatrixType the type of the matrix of which we are computing the LL^T Cholesky decomposition
+  * \tparam _UpLo the triangular part that will be used for the decompositon: Lower (default) or Upper.
+  *               The other triangular part won't be read.
+  *
+  * This class performs a LL^T Cholesky decomposition of a symmetric, positive definite
+  * matrix A such that A = LL^* = U^*U, where L is lower triangular.
+  *
+  * While the Cholesky decomposition is particularly useful to solve selfadjoint problems like  D^*D x = b,
+  * for that purpose, we recommend the Cholesky decomposition without square root which is more stable
+  * and even faster. Nevertheless, this standard Cholesky decomposition remains useful in many other
+  * situations like generalised eigen problems with hermitian matrices.
+  *
+  * Remember that Cholesky decompositions are not rank-revealing. This LLT decomposition is only stable on positive definite matrices,
+  * use LDLT instead for the semidefinite case. Also, do not use a Cholesky decomposition to determine whether a system of equations
+  * has a solution.
+  *
+  * Example: \include LLT_example.cpp
+  * Output: \verbinclude LLT_example.out
+  *
+  * \b Performance: for best performance, it is recommended to use a column-major storage format
+  * with the Lower triangular part (the default), or, equivalently, a row-major storage format
+  * with the Upper triangular part. Otherwise, you might get a 20% slowdown for the full factorization
+  * step, and rank-updates can be up to 3 times slower.
+  *
+  * This class supports the \link InplaceDecomposition inplace decomposition \endlink mechanism.
+  *
+  * Note that during the decomposition, only the lower (or upper, as defined by _UpLo) triangular part of A is considered.
+  * Therefore, the strict lower part does not have to store correct values.
+  *

+  * \ingroup Core_Module
+  *
+  * \brief Base class for all 1D and 2D array, and related expressions
+  *
+  * An array is similar to a dense vector or matrix. While matrices are mathematical
+  * objects with well defined linear algebra operators, an array is just a collection
+  * of scalar values arranged in a one or two dimensionnal fashion. As the main consequence,
+  * all operations applied to an array are performed coefficient wise. Furthermore,
+  * arrays support scalar math functions of the c++ standard library (e.g., std::sin(x)), and convenient
+  * constructors allowing to easily write generic code working for both scalar values
+  * and arrays.
+  *
+  * This class is the base that is inherited by all array expression types.
+  *
+  * \tparam Derived is the derived type, e.g., an array or an expression type.
+  *
+  * This class can be extended with the help of the plugin mechanism described on the page
+  * \ref TopicCustomizing_Plugins by defining the preprocessor symbol \c EIGEN_ARRAYBASE_PLUGIN.
+  *
+  * \sa class MatrixBase, \ref TopicClassHierarchy

+  * \brief Expression of a fixed-size or dynamic-size block
+  *
+  * \tparam XprType the type of the expression in which we are taking a block
+  * \tparam BlockRows the number of rows of the block we are taking at compile time (optional)
+  * \tparam BlockCols the number of columns of the block we are taking at compile time (optional)
+  * \tparam InnerPanel is true, if the block maps to a set of rows of a row major matrix or
+  *         to set of columns of a column major matrix (optional). The parameter allows to determine
+  *         at compile time whether aligned access is possible on the block expression.
+  *
+  * This class represents an expression of either a fixed-size or dynamic-size block. It is the return
+  * type of DenseBase::block(Index,Index,Index,Index) and DenseBase::block<int,int>(Index,Index) and
+  * most of the time this is the only way it is used.
+  *
+  * However, if you want to directly maniputate block expressions,
+  * for instance if you want to write a function returning such an expression, you
+  * will need to use this class.
+  *
+  * Here is an example illustrating the dynamic case:
+  * \include class_Block.cpp
+  * Output: \verbinclude class_Block.out
+  *
+  * \note Even though this expression has dynamic size, in the case where \a XprType
+  * has fixed size, this expression inherits a fixed maximal size which means that evaluating
+  * it does not cause a dynamic memory allocation.
+  *
+  * Here is an example illustrating the fixed-size case:
+  * \include class_FixedBlock.cpp
+  * Output: \verbinclude class_FixedBlock.out
+  *
+  * \sa DenseBase::block(Index,Index,Index,Index), DenseBase::block(Index,Index), class VectorBlock

+  * This class represents an expression of a generic nullary operator.
+  * It is the return type of the Ones(), Zero(), Constant(), Identity() and Random() methods,

+  *
+  * However, if you want to write a function returning such an expression, you
+  * will need to use this class.
+  *
+  * The functor NullaryOp must expose one of the following method:
+    <table class="manual">
+    <tr            ><td>\c operator()() </td><td>if the procedural generation does not depend on the coefficient entries (e.g., random numbers)</td></tr>
+    <tr class="alt"><td>\c operator()(Index i)</td><td>if the procedural generation makes sense for vectors only and that it depends on the coefficient index \c i (e.g., linspace) </td></tr>
+    <tr            ><td>\c operator()(Index i,Index j)</td><td>if the procedural generation depends on the matrix coordinates \c i, \c j (e.g., to generate a checkerboard with 0 and 1)</td></tr>
+    </table>
+  * It is also possible to expose the last two operators if the generation makes sense for matrices but can be optimized for vectors.
+  *
+  * See DenseBase::NullaryExpr(Index,const CustomNullaryOp&) for an example binding
+  * C++11 random number generators.
+  *
+  * A nullary expression can also be used to implement custom sophisticated matrix manipulations
+  * that cannot be covered by the existing set of natively supported matrix manipulations.
