Brep

class compas.geometry.Brep

Bases: Geometry

Contains the topological and geometrical information of a Brep shape.

This class serves as an interface for a Brep and allows instantiating a Brep object depending on the available Backend. Note: this is not a full implementation of Brep and rather relies on COMPAS’s plugin system for actual implementation.
