Rhino Solids Modeling

From TOI-Pedia


Solids in Rhino are multiple NURBS surfaces joined into one primitive. Primitives are basic geometric shapes like a cube, cone, sphere, cylinder and pyramid.

All operations concerning creating and editing solids can be found in the menu Solid

Creating Solids

Create basic geometry and derived geometric shapes from the upper section of this menu.

  • Box
  • Sphere
  • Cylinder
  • Cone
  • Truncated cone
  • Pyramid

  • Elipsoid
  • Paraboloid
  • Tube
  • Pipe: The pipe follows a selected curve. At different points on the curve different radii can be set. The pipe can also be made with different end caps. See the options in the command line when using the command
  • Slab: Creates a wall-like shape along a curve. Note: Choose the correct view to determine the offset direction (e.g. to set the ground plane of the slab)
  • Torus

Editing Solids

Create different shapes with other solids or polysurfaces. Edit operations can be found in the lower section of the Solid menu

Boolean Operations

  • Union: Makes from multiple polysurfaces one polysurface
  • Difference: Removes (sets of) polysurfaces from other (sets of) polysurfaces
  • Intersection: Keeps the shared parts of the polysurfaces

Edit Solid Edges

  • Fillet Edge > Fillet Edge: creates round edges
  • Fillet Edge > Blend Edge: almost similar to Fillet Edge, but has more control points
  • Fillet Edge > Chamfer Edge: creates cornered edges

Sometimes when you fillet edges, holes can appear on faces. To close these holes use: Cap Planar Holes

Extruding Faces

Except extruding complete planes, you can also extrude parts of faces. Two main options are:

  • Boss
  • Rib
