Couple of cone-y questions

Just in general, why are scripted/RhinoCommon cones created “upside-down”? I can understand that they are created from a revolve of a line passing through the base plane origin, but for practical purposes, most people create cones in the inverse way, starting from a circle at the base plane origin and going “upward” to the apex…

And, a Rhino.Geometry.Cone() object is also always created “solid”… Again, why? I know you can get just the cone part by using cone.ToBrep(False) or .ToSurface() or .ToRevSurface(), but it would seem more logical (to me) if the cone object was created open and then cap created later if desired…

Lastly, as a corrolary to the above, Rhino.Geometry.Mesh.CreateFromCone(cone) always produces a closed mesh cone. There is no easy way I can see to create an open mesh cone; creating a mesh from a RevSrf is not the same as you can’t specify the number of “around” and “vertical” divisions as you can with a normal mesh cone…
