prompt: "Implement AI-driven code generator for OpenSCAD"
</metadata>
<exploration>
The code generator was designed to translate natural language descriptions and extracted parameters into valid OpenSCAD code. Several approaches were considered:
1. Direct string manipulation for code generation
2. Template-based approach with parameter substitution
3. Modular approach with separate modules for different shape types
The modular approach was selected for its maintainability and extensibility.
</exploration>
<mental-model>
The code generator operates on a "shape-to-module" mapping paradigm, where each identified shape type corresponds to a specific OpenSCAD module. This mental model allows for clean separation of concerns and makes it easy to add new shape types.
</mental-model>
<pattern-recognition>
The implementation uses the Factory pattern for code generation, where different shape types are mapped to different module generators. This pattern allows for easy extension with new shape types.
</pattern-recognition>
<trade-off>
Options considered:
1. Generating raw OpenSCAD primitives directly
2. Using a library of pre-defined modules
3. Hybrid approach with both primitives and modules
The library approach was chosen because:
- More maintainable and readable code
- Easier to implement complex shapes
- Better parameter handling
- More consistent output
</trade-off>
<domain-knowledge>
The implementation required understanding of:
- OpenSCAD syntax and semantics
- Constructive Solid Geometry (CSG) operations
- Parametric modeling concepts
- 3D geometry fundamentals
</domain-knowledge>
<technical-debt>
The current implementation has some limitations:
- Limited support for complex nested operations
- No support for custom user-defined modules
- Basic error handling for invalid parameters
Future improvements planned:
- Enhanced error handling with meaningful messages
- Support for user-defined modules
- More sophisticated CSG operation chaining
