Crate ogeom_hlr 

Hidden line removal: projecting 3D shapes to annotated 2D edge sets for technical drawings.

Elsewhere: HLRAlgo, HLRBRep, HLRTopoBRep and HLRAppli.

Nothing in the modeling path depends on it, but producing a 2D drawing from a 3D model is a core CAD capability and not optional for a complete kernel.
