- Arc and circular slots available using single edge selection.
- `ExtendRadius` property to allow for tool compensation.
- Extend path start and end is available. Value is measured along the arc, not linear.
- Includes collision check for arc and circular slots.
- Add `CutPattern` feature, defaulting to `ZigZag`.
- Change inter-pass retractions to SafeHeight for multi-pass operations.
- Fix division by zero instance for particular Perpendicular use case.
- Synchronize property values with inputs in both the Property View and Tasks Editor windows.
- Change `LayerMode` default value to `Multi-pass`.
- Improve debug messaging.
- Consolidate code and remove unused code.
Path: fix exception thrown
New slotting operation:
- Accepts selection of up to two features.
- Selectable features include: faces, edges, and vertices.
- User may select a single face or edge, or a pair of features.
- The path may be extended at the start and end.
- The path may be reversed.
- The path may be altered to the perpendicular in some cases.
- A unique Slot icon is included.
- Includes simple collision detection with warning message.
Two new properties, `ExpandProfile` (length) and `ExpandProfileStepOver` (percent) added for new feature.
New feature converts the normal single offset profile into a compound profile containing multiple increasing/decreasing offsets.
The new feature clears a each layer completely before stepping down to the next layer.
Adjust sorting procedure in PathAreaOp due to `ExpandProfile` modifications to open edges code.
Implement an iterative version of the Ramer-Douglas-Peucker line
simplification algorithm
(https://en.wikipedia.org/wiki/Ramer%E2%80%93Douglas%E2%80%93Peucker_algorithm),
which reduces line complexity to a limited linear deviation from the
original polyline. The ability to reason about linear deflection is the
key improvement over the previous linear implementation.
Worst case complexity is O(n^2), but expected complexity for typical
cases is O(n log n). A potentially faster alternative would be to call
out to libclipper, treating the line as a closed polygon. However, in
practice, performance of this implementation seems good enough. A
complex 3d surface operation optimizes in a few seconds, and reduces
output gcode size from about 220MB with the previous implementation to
10MB.
The new `ShapeName` is the name of the FreeCAD shape file containing the 3D body of the cutter.
We might want to change the source of the `ShapeName` to the name of the first Body object in the shape file, rather than the name of the file itself.
