Needing help, working on architecture

cant figure out how to create subdivisions of objects faces and selecting specific subdivisions

Hello - please see

to get an idea of how Rhino and surfaces work. It is not like SketchUp, if that is what you are expecting…

Rhino 7 adds the ability to use subdivision surfaces.


Rhino SubDs are a bit different. They go to limit surface all the time. So you always see the smooth version of the surface. But, there are ways to extract different mesh levels if the mesh is needed:

  1. SubD - Smooth version
  2. Control Polygon - ExtractControlPolygon Command
  3. Level 1 -3 - Extract Render Mesh and use the SubD slider to control what level mesh to extract.

Of course the Subd can be converted to a NURBS by using the ToNurbs command.
