BrepGeometry

The BrepGeometry class represents the geometric structure of a 3D brep, including its faces and materials. It allows for defining and manipulating the geometry hierarchical relationships, such as setting parent-child relationships between geometries, with support for two parent geometries to create seamless Level of Detail (LOD) transitions.
