If you have a mouse with a scroll button, turnthe scroll button to zoom in and out. The easiest way is to hold down the Ctrl key and drag up and down in aviewport with the right mouse button. As with many things in Rhino, there are several ways to dothis. Sometimes you want to get closer to your objects or move back so you can see more.This is called zooming. Panning with Shift and the right mouse button. U In the Top viewport, drag with the right mouse button to pan the view. Dragging the right mouse button tomanipulate the view does not interrupt any commands you are using. You candrag with the right mouse button to pan. You have used the right mouse button to rotate in the Perspective viewport. As you work through theexercises, you will learn what commands do, when and how to use them and how todecide which command to use to accomplish your task. Rhino uses commands to accomplish various tasks. In the exercises, you will use Rhino’s navigation tools, shaded preview, render, anduse some basic object manipulation. If you have never worked with 3-D computer modeling before, Getting Started with3D, A Designer’s Guide to 3D Graphics and Illustration, by Janet Ashford and JohnOdam is one of several excellent books that will help you learn some of theterminology and basic principles of 3-D design on computers. If you have experience using a 3-D modeling program, the following exercises mayseem simple, but they will help you understand Rhino’s interface and navigationtools. Byrendering you can add color, texture, shadows, and lights. When you have a view you like, you can render the view. You can do this in both a wireframe viewand a shaded view. You can manipulate the views and look at your model from different angles easilyby dragging with your right mouse button. Rhino can create polygon mesh objects that approximate the NURBSobjects to export to those programs.įor additional information on Rhino features go to page 66.Ģ Your First LookWorking in 3-D on a computer requires that you visualize three-dimensional objectsdrawn on a two-dimensional medium- the computer screen. Polygon mesh objects are used by some programs for rendering and animation,stereolithography, VRML, and finite element analysis to approximate a smoothsurface. There are five fundamental geometric objects in Rhino: points, NURBS curves andsurfaces, and polygon meshes. Non-uniform rational B-splines (NURBS) geometry is a mathematicalrepresentation that can accurately define any shape from a simple line, circle, arc, orbox to the most complex 3-D free-form organic surface or solid.īecause of their flexibility and accuracy, NURBS models can be used in anyprocess from illustration and animation to manufacturing. You are free to create the model any way you want. With Rhino, you can create free-form curves,surfaces, and solids. You can modeland render objects that you could previously create only using software andhardware many times more expensive. With Rhino you canmodel anything from a heart valve to a ship hull and from a mouse to a monster.Rhino provides a flexible, accurate, and fast working environment. 57Create a Surface From Edge Curves 57Revolve a Curve Around an Axis 58ġ IntroductionRhinoceros is a 3-D NURBS modeling program for Windows. 45Enter Coordinates 45Draw the Pull Toy Body 45Draw the Axles and Wheel Hubs 46Draw the Lug Nuts 48Assign Colors 49Array the Lug Nuts 50Draw the Tires 50Mirror the Wheels 51Draw the Eyes 53Make the Pull Cord 54Try On Your Own 56Ħ Create Surfaces. 28Create the Body and Head Shapes 28Try on Your Own 43Look at the gallery images 44ĥ Create a Pull Toy. 17Start the Flashlight Model 17Draw the Body 18Cut the Reflector Shield 20Cut Out the Inside of the Flashlight Body 21Draw the Lens 23Draw the Switch 24Render the Flashlight with Color 24Try on Your Own 27Ĥ Create a Rubber Ducky. 6Rhino Commands 6Start Using Rhino 7Try on Your Own 10Navigating Around the Model 11Drag Objects 12Copy Objects 14Review 15Try on Your Own 15Repeat the Last Command 16Undo a Mistake 16ģ Create a Flashlight. 5NURBS 5Rhino’s Geometry Types 5Ģ Your First Look.
