This section Describes all of the Features in Rhino 3D. It should be Helpfull to read all
of these over and possibly print this out. I know you are thinking.....is this person crazy I
am not printing this out. But it will really help you.
Geometry Types in Rhino 3D
There are 5 basic geometry types in Rhino 3D: There are points, Surfaces, Curves, Solids,
and Polygon meshes. All Curves, Surfaces, and Solid are Nurbs Objects. Nurbs stands for
Non-Uniform Rationl B-Splines. You dont need to remember this though. Just remember that
Nurbs are very smooth. Rhino can make a Polygon meshed object out of Nurbs or vice versa
if you want to export them to a different program. But on to the Geometry itself!
Curves, Points, and Surfaces
Points: Point objects will mark a single spot in 3 Dimensional Space. They
are represented by a dot or a very small box. These are the most simple objects in Rhino
3d. Here is a Picture of a point in 3D space. These will be used a lot
even though they are the simplest objects.
Curves: Every Nurbs Surface Contain Curves. curves can take many shapes or forms.
Curves can match the edge of any surface you want.

Surfaces: Surface by definition is explained as a Matrix of spline based control
points and tangent line end points. These are all of course created in Rhino and most
other 3d Packages.
These are a few examples of Surfaces made in Rhino 3D.
Surfaces can be achieved in many different ways. You can loft a curve, revolve, extrude
and so on. You can also edit the sufaces by point editing. There will be more about these
modifiers later in this site.
