Consider what your final product will be. In general, you should spend some time editing your linework in Rhino - which can be much easier than Illustrator. Is a versatile and extremely useful command, there are several known issues which can be helped or eliminated by following the general preparation instructions provided.

We will be literally cutting sections and plans through your geometry, so the first step in Seeįor an extensive treatment of this process. This allows us to capture the linework of our 3D geometries from any viewport and project that linework onto a 2D plane. One of the most useful commands in Rhino is : Split and close objects at intersections. : Create a new solid from a set of objects' intersected volumes. : Subtract the volume of one object from another. Alternatively, if you know exactly what type of boolean operation you want you can type the command in directly. There are four different options, but using theĬommand (also found under the solid menu) will allow you to select your geometries and then click through the four options. We will cover just a few in detail - but you will find many more under "Surface Edit Tools" within the "Surface" menu and "Solid Edit Tools" within the "Solid" menu.īoolean operations will produce new geometry from two given geometries (sound familiar?). These tools will be pivotal for creating your double negative space. "Watertight" volumes require much less editing in Illustrator. This is a good habit to follow in general, but will be very helpful when we generate 2D linework from our 3D geometries. When doing so, it is important to get in the habit of making your volumes "watertight." That means - like a closed curve - there are no gaps in your polysurface. Notice that some of the options allow you to extrude in both directions, as well as adjust the direction of your extrusion.įinally, you can manually create polysurfaces by joining multiple surfaces. Once you have created a surface, whether planar or not, you can extrude that surface with theĬommand. Then use theĬommand (select the "cap" option to close the volume). First create a closed curve (no gaps in the curve), either with multiple single lines, curves, or a polyline. Additionally, the interface is different on each and it may be difficult to follow along.Īnother method for creating a "solid" is by extruding a If you are running Rhino on a Mac there is a good chance you'll run into issues that we cannot take the time to remedy. We will be teaching and working with Rhino on PC. For a comprehensive list of commands accessĪs you use various commands, you will notice that Rhino will guide you through the command, asking for various inputs along the way in the command bar. Rhino works with both text based commands typed directly and point-and-click visual menus. While the math behind NURBS is complex, the important thing to remember is that the geometry in Rhino is defined by control points that you can manipulate. Rhino can also deal with rational surfaces and meshes. Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces, and is the basis of 3D modeling in Rhino. Learning Rhino is like learning to speak a new language, and like learning any new software, can be very frustrating at first. Many plugins work with Rhino that do everything from parametric modeling to photo-realistic rendering. Rhino is a 3-D modeling software commonly used for industrial design, architecture, marine design, jewelry design, automotive design, CAD / CAM, rapid prototyping, product design as well as the multimedia and graphic design industries.
