Representation of canonical geometries

Rhino Rhino for Windows

Hi,

I was wondering that under the hood, canonical geometries like planes, cylinders, spheres etc. are represented as NURBS surfaces or does Rhino store them as canonical geometries?

Hello - normally as planes, spheres, surfaces of revolution etc. not NURBS. Same for lines, arcs, polylines. That’s not to say that every instance of these will something other than NURBS - they cal all be represented as NURBS but where possible they are in the more compact form. There’s also Extrusions of course.
