Description

Rhino can create, edit, analyze, and translate NURBS curves, surfaces, and solids in Windows. Rhino has limited support for polygon meshes. There are no limits on complexity, degree, or size.

NURBS

Non-Uniform Rational B-Splines (NURBS) are mathematical representations that can accurately define any shape from a simple 2-D line, circle, arc, or box to the most complex 3-D free-form organic surface or solid.

Because of their flexibility and accuracy, NURBS models can be used in any process from illustration and animation to manufacturing.

Features

User interface: extremely fast 3-D graphics, unlimited viewports, working perspective views, coordinate read-out, named views, named construction planes, customizable icons and user workspace, extensive on-line help, electronic updates, newsgroup support.

Construction aids: unlimited undo and redo, exact numeric input, object snaps, grid snaps, ortho, planar, construction planes, layers, background bitmaps, object hide/show, object lock/unlock.

Create curves: point, line, polyline, free-form curve, circle, arc, ellipse, rectangle, polygon, helix, spiral, conic, TrueType text, point interpolation, control points (vertices), sketch.

Create curves from other objects: extend, fillet, chamfer, offset, blend, from 2 views, cross section profiles, intersection, contour, section, border, silhouette, extract isopram, projection, pullback, sketch, wireframe, detach trim, 2-D drawings, flatten developable surfaces.

Edit curves: control points, edit points, handlebars, smooth, fair, change degree, add/remove knots, add kinks, rebuild, refit, match, simplify, change weight, make periodic, adjust end bulge, adjust seam.

Create surfaces: from 3 or 4 points, from 3 or 4 curves, from planar curves, rectangle, extrude, ribbon, rule, loft, sweep along a path, sweep along two rail curves, revolve, rail revolve, blend, patch, drape, point grid, heightfield, fillet, chamfer, offset, TrueType text.

Edit surfaces: control points, handlebars, change degree, add/remove knots, match, extend, merge, join, untrim, rebuild, shrink, make periodic, Boolean (union, difference, intersection).

Create solids: box, sphere, cylinder, tube, pipe, cone, truncated cone, ellipsoid, torus, extrude planar curve, extrude surface, cap planar holes, join surfaces, TrueType text.

Edit solids: fillet edges, extract surface, Booleans (union, difference, intersection).

Create meshes: from NURBS surfaces, from closed polyline, mesh face, plane, box, cylinder, cone, and sphere.

Edit meshes: explode, join, weld, unify normals, apply to surface.

Edit tools: cut, copy, paste, delete, delete duplicates, move, rotate, mirror, scale, stretch, align, array, join, trim, split, explode, extend, fillet, chamfer, offset, twist, bend, taper, shear, orient, flow along curve, smooth, project, object properties.

Analysis: point, length, distance, angle, radius, bounding box, normal direction, area, area centroid, area moments, volume, volume centroid, volume moments, curvature graph, geometric continuity, deviation, naked edges, nearest point.
