- 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.
Introduced FLOAT_EPSILON for robust floating point comparisons, resolving cases
where Z axis retract moves were missing after geometry recompute in 3D Surface
rotational scan operations. This prevents precision errors from causing the
cutter to skip intended lifts between rings or scan lines.
src/Mod/CAM/Path/Op/Surface.py
- Added FLOAT_EPSILON constant
- Updated Z move comparison logic to use tolerance
