 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 7.7.0 library](https://www.opencascade.com/content/overview)
-which performs much of the boolean operations involve in generating 3D solids.
