Modeling objects

Modeling commands are found in the Modeling Toolbar.
The geometry produced by these commands can result in surfaces or solids.

Surfaces and solids Surface and solid creation.

Surfaces

A surface is like a rectangular stretchy rubber sheet. All surface creation commands result in a NURBS surface. NURBS surfaces have an inherently rectangular organization and can represent simple shapes like planes and cylinders, as well as free-form, sculptured surfaces. Even a closed surface, like a cylinder, resembles a rectangular piece of paper that has been rolled up, with two opposite edges touching

A polysurface consists of two or more surfaces that are joined together.

Create a surface from points

  • Surface Surface: Draws a surface from specified corner points.
  • Plane Plane: Draws a rectangular planar surface.

Create a surface from curves

  • PlanarSrfPlanarSrf: Creates a planar surface from planar curves.
  • EdgeSrfEdgeSrf: Creates a surface from two, three, or four curves.
  • NetworkSrf NetworkSrf: Fits a surface through a network of crossing curves.
  • PatchPatch: Fits a surface through curves and point objects.
  • LoftLoft: Fits a surface through profile curves that define the surface shape.
  • SweepSweep: Fits a surface through a series of profile curves that define the surface cross-sections and one curve that defines a surface edge.
  • RevolveRevolve: Create a surface by revolving a profile curve around an axis.
  • Extrude CurveExtrude Curve: Creates a surface by tracing the path of a curve in a straight line.

Solids

Solids are formed whenever a surface or polysurface is completely closed, enclosing a volume within. Various commands create single-surface solids, polysurface solids, and extrusion solids.

Create single surface solids

A single surface can wrap around and join itself. Example commands include Sphere and Torus. Control points can be displayed on single-surface solids and moved to change the surface.

  • TorusTorus: Draws a torus (doughnut shape).
  • SphereSphere: Draws a solid sphere.

Create polysurface solids

A polysurface consists of two or more surfaces that are joined together. Pyramid, Cone, and Cylinder are examples of commands that create polysurface solids.

  • BoxBox: Draws a solid box.
  • PyramidPyramid: Draws a pyramid.
  • CylinderCylinder: Draws a polysurface cylinder.
  • ConeCone: Creates a surface cone.
  • TubeTube: Draws a closed cylinder with a concentric cylindrical hole.

Create solids from curves or surfaces

RhinoLands also allows the creation of solids by extending an existing curve or surface along a linear path, resulting in a surface or, if closed, a solid with a consistent cross-sectional shape.

  • Extrude CurveExtrude Curve: Creates a surface by tracing the path of a curve in a straight line.
  • Extrude SurfaceExtrude Surface: Creates a solid by tracing the path of the surface edges in a straight line.
  • PushPull PushPull: Extrudes a polysurface face to interactively add or remove volumes on the polysurface.
