My last Wish to Fernando is to guide us to create our own Snapping Objects. 

This means to reveal the Anatomy of the HighwayConstKit and the secret of the maybe hidden??? Geometry.

It's not just to replace road parts, it's more like building libraries of City-Blocks, Minecraft like Cubes and modular SciFi environments.

Or can we have one last new Object: A customizable Snap Object with RB&SM included like HCK?
One last idea: put a custom mesh.snap file to the Rigidbody folder would be easy...
