This highway intersection is modelled with cinema 4d r19. Its so useful.

If you want to add or remove something you can do. we didnt crop any object as well as we do. so many object still with cloner and symetry. Bcs of that you turn of all object or open.

Other format are fbx and obj. They are also useful but you have to know that hasnt any cloner or symetry. All object made editable. bcs of that files are a little big size file.

There are two type every format.

Thanks for interesting
