XbimGeometry

XbimGeometry is part of the Xbim Toolkit.

It contains the the Geometry Engine and Scene processing, which provide geometric and topological operations to enable users to visualise models in 3D models, typically as a Tesselated scene or mesh.

The native Geometry Engine is built around the open source Open Cascade 7.3 library which performs much of the boolean operations involve in generating 3D solids.
