This module provides make_gear_figure with a compatible signature but implements the limited subset of functionality that yapCAD requires. The implementation relies only on the Python standard library to avoid adding heavy runtime dependencies such as SciPy.

yapcad.contrib.figgear.make_gear_figure(m: float, z: int, alpha_deg: float, bottom_type: str, **kwargs) → Tuple[List[Tuple[float, float]], Dict[str, float]][source]: Generate a 2D involute spur gear profile.

Module contents

Utility modules that are vendored or optional extras.

Currently includes a lightweight port of figgear’s involute gear generator so that yapCAD can generate gear profiles without requiring an external dependency at build/test time.
