+
+## Project Overview
+Fluency is a CAD (Computer Aided Design) application built with Python/PySide6 that provides parametric 3D modeling through a timeline-based project system. The application combines 2D sketching with constraint solving, 3D visualization using VTK, and SDF (Signed Distance Function) based mesh generation.
+
+## Common Commands
+
+### Development Environment Setup
+```bash
+# Activate virtual environment (if exists)
+source .venv/bin/activate
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+### Running the Application
+```bash
+# Run the main application
+python main.py
+
+# Run with debugging
+python -u main.py
+```
+
+### UI Development
+```bash
+# Convert Qt Designer UI file to Python code
+pyside6-uic gui.ui > Gui.py -g python
+```
+
+### Building Executable
+The project uses Nuitka for compilation (configured in `main.py` header):
+```bash
+# Build standalone executable
+nuitka --standalone --plugin-enable=pyside6 --plugin-enable=numpy --macos-create-app-bundle main.py
+```
+
+### Testing
+```bash
+# Run mesh generation test
+python meshtest.py
+```
+
+## Architecture Overview
+
+### Core Components
+
+#### Main Application (`main.py`)
+- **MainWindow**: Central UI controller that manages all widgets and user interactions
+- **Project System**: Hierarchical structure: `Project → Timeline → Component → Sketch/Body`
+- **Signal-based Communication**: Qt signals coordinate between 2D sketching and 3D rendering
+
+#### Project Hierarchy
+```
+Project
+├── Timeline (list of Components)
+└── Component
+    ├── Sketches (dict)
+    ├── Bodies (dict) 
+    └── Connectors (for assembly)
+```
+
+#### Drawing Modules (`drawing_modules/`)
+- **SketchWidget** (`draw_widget_solve.py`): 2D parametric sketching with SolverSpace constraint solving
+- **VTKWidget** (`vtk_widget.py`): 3D visualization and mesh interaction using VTK
+- **PyVistaWidget** (`vysta_widget.py`): Alternative 3D rendering backend
+
+#### Mesh Generation (`mesh_modules/`)
+- **VESTA** (`vesta_mesh.py`): Multi-threaded SDF-to-mesh conversion using marching cubes
+- **Interactor Mesh** (`interactor_mesh.py`): Simplified edge-based meshes for 3D selection
+- **Simple Mesh** (`simple_mesh.py`): Basic mesh utilities
+
+### Data Flow Architecture
+
+#### 2D to 3D Pipeline
+1. **2D Sketching**: User draws in SketchWidget using Qt coordinate system
+2. **Constraint Solving**: SolverSpace resolves geometric constraints
+3. **SDF Generation**: Sketch converted to Signed Distance Functions for 3D operations
+4. **Mesh Generation**: VESTA generates triangle meshes from SDF using marching cubes
+5. **3D Rendering**: VTK displays both solid meshes and interactive edges
+
+#### Signal Flow (from `doc/flow.md`)
+- 2D QPoint → cartesian space → SolverSpace dict → constraint solving → display
+- 3D mesh selection → projection to 2D → sketch widget integration
+
+### Key Classes
+
+#### Core Data Structures
+- **Sketch**: 2D geometric data with origin, normal, points, and constraints
+- **Body**: 3D mesh representation containing SDF objects and interactor meshes  
+- **Component**: Container grouping related sketches and bodies
+- **Interactor**: Simplified edge-based mesh for 3D manipulation
+
+#### Constraint Solving
+The application uses `python_solvespace` for parametric constraint solving:
+- Point-to-point constraints
+- Distance constraints
+- Horizontal/vertical line constraints
+- Point-to-line constraints
+
+### Technology Stack
+- **GUI**: PySide6 (Qt for Python)
+- **3D Graphics**: VTK for rendering, PyVista as alternative
+- **Constraint Solving**: SolverSpace for parametric geometry
+- **Mesh Generation**: SDF library with custom VESTA marching cubes implementation
+- **Scientific Computing**: NumPy for mathematical operations
+
+## Development Workflow
+
+### Adding New Sketch Tools
+1. Add UI button in `gui.ui`
+2. Convert UI: `pyside6-uic gui.ui > Gui.py -g python`  
+3. Connect signal in `MainWindow.__init__()`
+4. Implement tool logic in `SketchWidget`
+
+### Adding New 3D Operations
+1. Extend operation buttons in the Modify group
+2. Implement operation logic using SDF functions
+3. Update Body creation and timeline management
+4. Handle interactor mesh generation for selection
+
+### Debugging Tips
+- Monitor solver results through `SolverSystem` status
+- Use VTK's built-in debugging for rendering issues
+- Check coordinate transformations between 2D sketch and 3D space
+- Verify SDF function outputs before mesh generation
+
+### File Structure
+- `main.py`: Application entry point and main window
+- `Gui.py`: Auto-generated UI code (do not edit directly)
+- `gui.ui`: Qt Designer UI definition file
+- `drawing_modules/`: 2D and 3D rendering widgets
+- `mesh_modules/`: Mesh generation and processing
+- `doc/`: Architecture and command documentation
+
+## Dependencies
+Primary external libraries:
+- `PySide6`: Qt GUI framework
+- `vtk`: 3D visualization toolkit
+- `python-solvespace`: Constraint solving
+- `sdf`: Signed Distance Function operations
+- `numpy`: Numerical computations

+
+## Code Conventions
+
+### General
+- Line length: **100 chars** (black/ruff config)
+- Target Python: **3.10+** (uses `from __future__ import annotations`, walrus, pattern matching)
+- Docstrings: Google/NumPy style preferred
+- Logging: `logger = logging.getLogger(__name__)` with `logging.DEBUG` level
+
+### OCC / OCP
+- Always use `is not None` for OCP objects — `TopoDS_Shape.__bool__` can be falsy even for valid shapes
+- `BRepBuilderAPI_MakeFace.Add(wire)` expects a `TopoDS_Wire`. `wire.Reversed()` returns `TopoDS_Shape` → cast via `_TopoDS.Wire_s(wire.Reversed())`
+- Face normal direction: check `face.Orientation()` vs `TopAbs_REVERSED` — a REVERSED face's outward normal is the NEGATION of the surface axis
+- `TopoDS_Wire_s(shape)`, `TopoDS_Face_s(shape)` — use `_s` suffix from OCP for downcasts
+- Mesh: `BRepMesh_IncrementalMesh(shape, tol, False, 0.15, True)` — default deflection 0.15 rad for smooth curves
+
+### Extrude / Cut Workflow
+- Snapshot `list(self._current_component.bodies.items())` **BEFORE** `add_body()` — the new body must not be in the target set
+- Cut targets the **source body** (`sketch._source_body_id` from face pick), not `bodies[0]`
+- The fix: apply boolean to **target** geometry, then remove tool body
+- Plain extrude with holes: inner wires must have **OPPOSITE** geometric winding to the outer wire (see `build_face_geometry` and `_loop_signed_area`)
+
+### Sketch / Solvers
+- `python_solvespace` has NO remove API for entities/constraints. Deleting requires: drop from `_points`/`_lines`, prune `_constraint_log`, `_rebuild_solver()` (recreates entire system), `_rebuild_labels()`, re-solve
+- `_constraint_log`: each entry is `{"type": str, "ids": tuple[int,...], "params": tuple, "labels": set[str]}`
+- Constraint labels: stored on **point** entities for paintEvent rendering; rebuilt via `_rebuild_labels()`
+- Line constraints (`horizontal`/`vertical`/`parallel`/`perpendicular`) need the **line's** solver handle, not a point's. Use `_find_line_sketch_entity()` to get the correct handle
+- External entities (underlay): `is_external=True`, `is_construction=True`, fixed in solver (always `dragged`). Stored in `_external_entity_ids`, excluded from `_line_segments()`, `get_polygon_points()`, `get_closed_loops()`, `detect_faces()`, `get_geometry()`
+
+### Face Detection
+- `get_closed_loops()`: uses snapped-coordinate graph (`_SNAP_TOL = 1e-4`) from line endpoint adjacency. Only accepts simple cycles (all nodes degree 2)
+- `detect_faces()`: even-odd nesting rule via `_loop_contains`. Even depth = outer boundary, odd = hole
+- `_loop_rep_point`: midpoint between centroid and first vertex. **Fragile** — can land inside a nested shape for certain geometries (e.g., a small hole near the centroid's direction from the first vertex)
+- `_loop_signed_area`: shoelace formula for polygons, `πr²` (positive = CCW) for circles
+
+### Rendering
+- **OCCRenderer** is the main renderer (not pygfx). Uses `AIS_Shape`, `V3d_Viewer`, `AIS_InteractiveContext`
+- Face pick: `pick_planar_face(x, y)` → `MoveTo` → `DetectedShape` → `TopoDS_Face_s` → `BRepAdaptor_Surface` plane check
+- Highlight: `highlight_face(face)` creates a transparent AIS overlay; `clear_face_highlight()` removes it
+- Preview: `preview_shape(shape)` for live transparent extrude preview
+- Navigation: Left=orbit, Middle=pan, Wheel=zoom. **Right is RESERVED** — check user before reassigning
+
+### Paint-Event Safety
+- Every constraint-tag rendering loop wraps each entry in `try/except` so a bad entry (dangling id, corrupted geometry) doesn't crash the entire paint event
+- `_point_world()` and `_entity_anchor()` return `None` (not raise) for malformed input
+
+---
+
+## Known Bugs & Fix Patterns
+
+### 1. Hole Orientation in Extrusion (FIXED 2026-07-03)
+**Symptom**: Inner shapes (circle/triangle/slot) inside a rectangle become solid islands instead of holes when extruding, depending on drag direction.
+
+**Root Cause**: `wire_loop` in `build_face_geometry` unconditionally reversed hole wires (`w.Reversed()`). When the outer polygon was CW-winding (e.g., dragging from top-left to bottom-right), the reversed inner had the SAME effective direction as the outer, making OCC treat it as solid.
+
+**Fix**: Added `_loop_signed_area()` to compute geometric winding. Hole wires are only reversed when their natural winding matches the outer's (ensuring opposite winding for holes).
+
+**Relevant code**: `sketch.py`, `build_face_geometry()` and `_loop_signed_area()`
+
+### 2. _loop_rep_point Fragility (KNOWN)
+**Symptom**: Face detection fails when a nested shape contains the outer loop's representative point (midpoint between centroid and first vertex).
+
+**Would-be fix**: Use a guaranteed-interior point (maximum inscribed circle center or perturbed centroid) instead of the centroid-first-vertex midpoint.
+
+### 3. Extrude Cut / Target Selection (FIXED 2026-06-29)
+**Symptom**: Cut created a separate "cavity-shaped" body next to the original instead of modifying the target.
+
+**Fix**: Boolean result stored on TARGET body geometry; tool body removed from component. Auto-target via `sketch._source_body_id`.
+
+### 4. Workplane Preservation (FIXED 2026-06-29)
+**Symptom**: Sketch placed on a face lost its workplane after being added to component.
+
+**Fix**: Copy `occ_sketch` workplane fields into `Sketch` dataclass BEFORE `apply_workplane()`.
+
+---
+
+## API Quirks
+
+- **`QPoint(0,0)`**: falsy via `isNull()` in PySide6 → always use `is not None` for `Optional[QPoint]`
+- **`QMouseEvent`/`QPainterPath`**: live in `PySide6.QtGui` (NOT `QtCore`)
+- **`BRepBuilderAPI_MakeFace.Add()`**: needs `TopoDS_Wire`. `wire.Reversed()` returns `TopoDS_Shape` — cast via `TopoDS_Wire_s()`
+- **python_solvespace**: NO entity/constraint remove API — workaround via `_rebuild_solver()`. Parameters read via `solver.params(handle.params)` → returns `(x, y)` tuple
+- **OCGeometryKernel.extrude**: unwraps `OCCGeometryObject`, raw `TopoDS_Shape`, or cadquery `Workplane`. Always use `is not None` for the shape (not truthiness)
+- **Sketch._source_body_id**: dynamic attribute set on `Sketch` dataclass, set during face-pick flow
+- **`_get_shape(obj)`**: returns `obj.shape.wrapped` for `OCCGeometryObject`, `obj.shape` for raw shapes, `None` for empty. Use `is not None` guards everywhere
+
+---
+
+## Memory / Agent Context
+
+This project has extensive Pi memory (hermes-memory) for:
+- `project="fluency"` with `target="failure"`: bugs, fixes, corrections, insights
+- `project="fluency"` with `target="memory"`: conventions, decisions, workflow patterns
+- Available skills: `fix-cad-app-pipeline`, `refactor-from-cadquery-to-ocp`
+
+Key memory queries for debugging:
+- "hole orientation" → `_loop_signed_area` / `build_face_geometry` fix
+- "extrude cut auto-target" → cut/target body fix
+- "workplane preservation" → _add_sketch_to_component fix
+- "_loop_rep_point" → face detection fragility
+- "paint-event safety" → try/except per entry pattern
+- "solver rebuild" → delete workflow via _rebuild_solver
+- "face pick origin" → pick_planar_face face bbox centre

+# Realistic Render View — Implementation Plan
+
+## Context
+
+Add a **"Render"** feature to Fluency CAD that opens a separate window for photorealistic rendering of the selected component or assembly (like KeyShot/Cacles).
+
+**Constraints:**
+- Open in a **new window** — don't clutter the workspace
+- **Keep existing OCCRenderer** for the interactive 3D viewport — untouched
+- Render backend must be a **separate, swappable module** so we can change the renderer later
+- Use **Mitsuba 3** as the initial backend (`pip install mitsuba`, ~50MB)

+## Material Presets
+
+| Preset | Color | Metallic | Roughness | BSDF |
+|--------|-------|----------|-----------|------|
+| Brushed Steel | (0.65, 0.67, 0.72) | 0.9 | 0.35 | roughconductor |
+| Polished Chrome | (0.8, 0.8, 0.8) | 1.0 | 0.05 | roughconductor |
+| Brushed Aluminum | (0.75, 0.75, 0.75) | 0.85 | 0.25 | roughconductor |
+| Copper | (0.95, 0.64, 0.54) | 0.95 | 0.15 | roughconductor |
+| Gold | (1.0, 0.76, 0.33) | 1.0 | 0.1 | roughconductor |
+| Blackened Steel | (0.15, 0.15, 0.17) | 0.8 | 0.4 | roughconductor |
+| Matte Plastic | (0.2, 0.5, 0.8) | 0.0 | 0.6 | plastic |
+| Glossy Plastic | (0.2, 0.5, 0.8) | 0.0 | 0.1 | plastic |
+| White Nylon | (0.85, 0.85, 0.83) | 0.0 | 0.45 | plastic |
+| Black ABS | (0.05, 0.05, 0.05) | 0.0 | 0.35 | plastic |
+| Red PA12 | (0.75, 0.08, 0.08) | 0.0 | 0.4 | plastic |
+| Rubber | (0.1, 0.1, 0.1) | 0.0 | 0.9 | diffuse |
+| Ceramic White | (0.92, 0.91, 0.88) | 0.0 | 0.15 | dielectric |
+| Glass | (0.95, 0.95, 0.95) | 0.0 | 0.0 | dielectric |
+| Wood | (0.6, 0.4, 0.2) | 0.0 | 0.7 | diffuse |
+
+**Note:** Mitsuba pip installs don't include spectral metal data files (iron.spd, copper.spd, etc.), so metal presets use `material="none"` with `specular_reflectance` set to the metal color instead.
+
+---
+
+## Risks & Mitigations
+
+| Risk | Mitigation |
+|------|-----------|
+| Mitsuba not installed | Graceful error: "pip install mitsuba" shown in UI |
+| Slow CPU rendering | Default to low SPP (64) for preview; offer GPU variant if CUDA available |
+| Large meshes slow to tessellate | Progress indicator; optional mesh decimation |
+| Mitsuba STL/OCC compatibility | Test tessellation quality; tune `linear_deflection` |
+
+---
+
+## Estimated Effort
+
+- **Phase 1** (abstract backend + OCC→mesh + Mitsuba impl): ~4-6 hours
+- **Phase 2** (render window UI + material presets): ~3-4 hours
+- **Phase 3** (polish, export, swap test): ~2-3 hours
+- **Total**: ~9-13 hours

bklronin	fe23ca610c	feat: Replace SDF kernel with OpenCASCADE, VTK with pygfx Major architecture migration: - Remove SDF-based geometry kernel (sdf/) - Remove VTK renderer (drawing_modules/) - Remove old mesh modules (mesh_modules/) New components: - geometry/base.py: Abstract geometry kernel interface - geometry_occ/kernel.py: OpenCASCADE implementation via CadQuery/OCP - geometry_occ/sketch.py: 2D sketching with constraint solving - rendering/base.py: Abstract renderer interface - rendering/pygfx_renderer.py: WebGPU-based renderer - models/data_model.py: Project, Component, Sketch, Body classes - main.py: New Qt-based application Features: - STEP/IGES import/export - Exact BRep geometry (vs approximate SDF mesh) - Parametric sketching with constraints - Boolean operations (union, difference, intersection) - Fillet and chamfer operations - Modern pygfx renderer (~30MB vs VTK ~200MB) Dependencies: - cadquery >= 2.4 - ocp >= 7.9.3 - pygfx >= 0.7.0 - wgpu >= 0.19.0 - PySide6 >= 6.9.0	2026-03-14 08:45:07 +01:00
bklronin	d6044e551a	- Improved sketching	2025-11-16 17:48:05 +01:00
bklronin	11d053fda4	Fix sketcher mode handling to prevent unintended line creation during drag operations Major changes: - Fixed right-click handler to directly set mode to NONE instead of relying on main app signal handling - Added safety checks in left-click handler to prevent drawing when no draggable point is found in NONE mode - Enhanced mode compatibility by treating Python None as SketchMode.NONE in set_mode() method - Added comprehensive debug logging for mode changes and interaction state tracking - Resolved integration issue where persistent constraint modes were prematurely reset by main app - Ensured point dragging is only enabled in NONE mode, preventing accidental polyline creation This fixes the reported issue where deactivating the line tool would still create lines when dragging, and ensures proper mode transitions between drawing tools and selection/drag mode.	2025-08-16 22:30:18 +02:00
