Billy Huddleston b5d97057be CAM: Introduce unified ToolBit parameter migration logic for Bullnose tools
- Added new migration system to handle legacy parameter conversion for ToolBit assets and objects.
- Implemented ParameterAccessor abstraction for consistent access to dicts and FreeCAD objects.
- Centralized migration logic for CornerRadius from TorusRadius or FlatRadius/Diameter, restricted to Bullnose shape-type.
- Updated asset and object initialization to use migration logic and filter Bullnose parameters.

src/Mod/CAM/Path/Tool/camassets.py:
- Integrate new migration logic for ToolBit assets using ParameterAccessor and migrate_parameters.
- Ensure shape-type is set before parameter migration; only write changes if migration occurred.

src/Mod/CAM/Path/Tool/toolbit/migration.py:
- Add ParameterAccessor class and migrate_parameters function for unified migration.
- Handle legacy parameter conversion for Bullnose tools.

src/Mod/CAM/Path/Tool/toolbit/models/base.py:
- Apply migration logic to ToolBit objects on restore.
- Filter Bullnose parameters to remove FlatRadius after migration.

src/Mod/CAM/Path/Tool/shape/models/bullnose.py:
- Add filter_parameters method to remove FlatRadius for Bullnose.

src/Mod/CAM/Path/Op/SurfaceSupport.py:
- Derive FlatRadius from CornerRadius and Diameter if both are present.

src/Mod/CAM/Path/Op/Surface.py:
- Remove obsolete setOclCutter method.

Overview

  • Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters.

  • Create 3D from 2D and back FreeCAD lets you sketch geometry-constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings.

  • Designed for your needs FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture, whether you are a hobbyist, programmer, experienced CAD user, student or teacher.

  • Cross platform FreeCAD runs on Windows, macOS and Linux operating systems.

  • Underlying technology

    • OpenCASCADE A powerful geometry kernel, the most important component of FreeCAD
    • Coin3D library Open Inventor-compliant 3D scene representation model
    • Python FreeCAD offers a broad Python API
    • Qt Graphical user interface built with Qt

Installing

Precompiled packages for stable releases are available for Windows, macOS and Linux on the latest releases page.

On most Linux distributions, FreeCAD is also directly installable from the software center application.

For weekly development releases visit the releases page.

Other options are described on the wiki Download page.

Compiling

FreeCAD requires several dependencies to correctly compile for development and production builds. The following pages contain updated build instructions for their respective platforms:

Reporting Issues

To report an issue please:

  • Consider posting to the Forum, Discord channel, or Reddit to verify the issue;
  • Search the existing issues for potential duplicates;
  • Use the most updated stable or development versions of FreeCAD;
  • Post version info from Help > About FreeCAD > Copy to clipboard;
  • Restart FreeCAD in safe mode Help > Restart in safe mode and try to reproduce the issue again. If the issue is resolved it can be fixed by deleting the FreeCAD config files.
  • Start recording a macro Macro > Macro recording... and repeat all steps. Stop recording after the issue occurs and upload the saved macro or copy the macro code in the issue;
  • Post a Step-By-Step explanation on how to recreate the issue;
  • Upload an example file (FCStd as ZIP file) to demonstrate the problem;

Note

The FPA offers developers the opportunity to apply for a grant to work on projects of their choosing. Check jobs and funding to know more.

Usage & Getting Help

The FreeCAD wiki contains documentation on general FreeCAD usage, Python scripting, and development. View these pages for more information:

The FreeCAD forum is a great place to find help and solve specific problems when learning to use FreeCAD.
