@@ -43,6 +43,7 @@ Domain model, geometry, and CNC primitives organized into namespaces:
- **Converters** (`Converters/`, `namespace OpenNest.Converters`): Bridges between CNC and Geometry — `ConvertProgram` (CNC→Geometry), `ConvertGeometry` (Geometry→CNC), `ConvertMode` (absolute↔incremental).
- **Math** (`Math/`, `namespace OpenNest.Math`): `Angle` (radian/degree conversion), `Tolerance` (floating-point comparison), `Trigonometry`, `Generic` (swap utility), `EvenOdd`, `Rounding` (factor-based rounding), `ExpressionEvaluator` (arithmetic expression parser for G-code variable expressions with `$name` references). Note: `OpenNest.Math` shadows `System.Math` — use `System.Math` fully qualified where both are needed.
- **CNC/CuttingStrategy** (`CNC/CuttingStrategy/`, `namespace OpenNest.CNC`): `ContourCuttingStrategy` orchestrates cut ordering, lead-ins/lead-outs, and tabs. Includes `LeadIn`/`LeadOut` hierarchies (line, arc, clean-hole variants), `Tab` hierarchy (normal, machine, breaker), and `CuttingParameters`/`AssignmentParameters`/`SequenceParameters` configuration.
- **Diagnostics** (`Diagnostics/`, `namespace OpenNest.Diagnostics`): `PlateOverlapAnalyzer.Capture` owns clean drawing entities and poses; `Analyze` returns read-only world-coordinate, hole-subtracted overlap fragments by input-index pair, with explicit issues for uncheckable inputs. It reuses `Collision.Check` without changing engine overlap semantics. Check `IsComplete` before treating an empty report as clear. See [material-overlap diagnostics](docs/geometry/visual-overlap-check.md) for the API, snapshot ownership, and numeric limits.
- **Collections** (`Collections/`, `namespace OpenNest.Collections`): `ObservableList<T>`, `DrawingCollection`.
- **CutOffs** (`namespace OpenNest`): `CutOff` (axis-aligned cut line with position, axis, optional start/end limits), `CutOffAxis` enum (`Horizontal`, `Vertical`), `CutOffSettings` (clearance, overtravel, min segment length, direction), `CutDirection` enum (`TowardOrigin`, `AwayFromOrigin`). Cut-offs generate CNC `Program` objects with trimmed line segments that avoid parts.
- **Splitting** (`Splitting/`, `namespace OpenNest`): `DrawingSplitter` splits a Drawing into multiple pieces along split lines. `ISplitFeature` strategy pattern with implementations: `StraightSplit` (clean edge), `WeldGapTabSplit` (rectangular tab spacers on one side), `SpikeGrooveSplit` (interlocking spike/V-groove pairs). `AutoSplitCalculator` computes split lines for fit-to-plate and split-by-count modes. Supporting types: `SplitLine`, `SplitParameters`, `SplitFeatureResult`.
