Use Cases & Benefits
- Provides a Pythonic parametric CAD modeling framework for 2D and 3D boundary representation (BREP) using the Open Cascade kernel.
- Enables algebraic, readable, and composable CAD design with minimal internal state and strong Python integration for precise manufacturing models.
- Use for creating custom 3D printable parts and assemblies with parametric control and export to common CAD formats like STEP and STL.
- Use for automating CNC machining and laser cutting workflows by scripting complex geometry and feature placement programmatically.
- Use for extending CAD functionality by subclassing base objects to build reusable parametric components and design patterns.
