Course Arch 100b
Date 2012/02/10
Learning Objectives This workshop will focus on the best practices in 3d modeling. An introduction to NURBS surface modeling in Rhino with emphasis on precision modeling in 3d space. This will be followed by an overview of modeling using 2d drawings, such as plans / sections or jigs.
  • Understand the differences between meshes and NURBS surfaces.
  • Be able to precisely model a variety of surfaces, from flat planar surfaces (walls, floors) to curved surfaces.
  • Be able to edit and control built surfaces.
Uses Tool(s) Rhinoceros , Illustrator CS5

Lecture 6: 3d Modeling in Rhino

  • NURBS VS Mesh
    • What makes up a NURBS Surfaces?
    • What happens as I edit a NURBS Surface?
  • Creating Surfaces:
    • Planar Surfaces: Plane, Plane (Vertical), PlanarSrf, PlaneThroughPt, CutPlane,
    • Extruded Surfaces: ExtrudeCrv, ExtrudeCrvAlongCrv, ExtrudeCrvTapered, ExtrudeCrvPoint, Ribbon, Fin
    • Non-Planr Surfaces: SrfPt, EdgeSrf, Loft, Revolve, RailRevolve, Sweep1, Sweep2
  • Editing Tools:
    • Boolean Commands, ExtendSrf, FilletSrf, ChamferSrf, Variable Fillet / Blend, Connect Surfaces, BlendSrf, OffsetSrf, Unroll
  • Curve Extractions:
    • Project, Pullback, Interpolate on Surface, DupEdge, DupBorder, Extract Isocurve, Extract Point, Extract Curve, Extract Wireframe, Section, Contour
