Solid objects

A solid is a surface or polysurface that encloses a volume. Solids are created anytime a surface or polysurface is completely closed. Rhino creates single-surface solids, polysurface solids, and extrusion solids.

Draw single surface solids

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

Ellipsoid

Draw a solid ellipsoid.

Sphere

Draw a solid sphere.

SphereTangentToThreeSurfaces

Create a spherical surface of a given radius tangent to the three selected surfaces.

Torus

Draw a NURBS torus (donut shape).

Draw polysurface solids

Some Rhino commands create polysurface solids. A polysurface consists of two or more surfaces that are joined together. A polysurface that encloses a volume of space defines a solid. Pyramid, Cone, and Truncated Cone are examples of commands that create polysurface solids.

The SolidPtOn command turns on grip points for polysurfaces, which act like control points.

Box

Draw a solid box.

Cone

Creates a surface cone.

Cylinder

Draw a polysurface cylinder.

Paraboloid

Draw a parabolic surface or capped solid.

Pyramid

Draw a pyramid.

TruncatedCone

Draw a NURBS truncated cone.

TruncatedPyramid

Draw a pyramid whose apex is truncated by a plane.

Tube

Draw a closed cylinder with a concentric cylindrical hole.

Create solid object from curves or surfaces

Boss

Extrude closed planar curves normal to the curve plane toward a boundary surface where the boundary surface is trimmed and joined to the extruded objects.

ExtrudeCrv

Drive closed planar curves in a straight line.

ExtrudeSrf

Drive surface edges in a straight line to create a solid.

Pipe

Create a surface, polysurface, or extrusion object with a circular profile around a curve.

Rib

Extrude a curve in two directions to a boundary surface.

Slab

Offset a polyline, and extrude and cap the result to create a solid.
