Chapter 1: Before you start.

Chapter 1: Before you start.

Notes: Blue and red dots appears while you play your videos. Whenever you see a Red Solid Dot, it means that a Left Click was made. Whenever you see a Blue Solid Dot, it means a Right Click was made. Remember that in Rhino, the left mouse button selects objects and picks locations. The right mouse button has several functions including panning and zooming, popping up contest-sensitive menu, and acting the same way as pressing the Enter key.

Before you start. Key things to remember.

Knowing where the tool-bars are is a plus in

Rhino. Also, remember that many buttons have

both, a command for the Left Click, and a com-

mand for the Right Click. Keep your eyes open for these icons.

Tooltips tell what each button does. Move the pointer

over a button without clicking it. A

small yellow tab with the name

of the command

appears.

Learn how toolbars access shortcuts to commands and options. You can float a toolbar anywhere on the screen, or dock it at the edge of the graphics area.

Learn how to utilize the features of Rhino’s interface.

Chapter 2: How to select objects.

Chapter 2: How to select objects.

Notes: The select toolbar is one of those toolbars that you will use all the time. You can select almost all kind of objects from this toolbar. To add to your selection set, hold the Shift key down while making another selection. You can hide, lock, and select objects by layer too. Keep an eye on this toolbar in this chapter. There are more toolbars inside the Select toolbar, such as Select Points.

How to select objects. Key things to remember.

You can select more than one object using a win-dow. You have two op-

tions: one is using a win-dow from left to right,

and the second option is, to select from right to

left. The second option is called “crossing window”.

When you draw the crossing selection

box, you will see a dotted rectangle.

Learn how toolbars access shortcuts to commands and op-tions. The Sel_Curves toolbar selects curves that are open, short, or closed. You can even type the Maximum length of the curve, and Rhino will find or se-lect all of them for you.

Learn how to select objects.


Chapter 3: Curves.

Chapter 3: Curves.

Notes: There are many curve tools that do have the option to Undo in the middle of the command. Keep your eyes open for these options. You do not want to select the normal Undo, since this will cancel and undo all your work.

Curves Key things to remember.

There are many options for drawing curves in

Rhino 4.0. You should pay attention to those

options since a good 2D drawing may be the key

to a perfect 3D model. Use all the tools in

all the units at the same time. You

can even start your drawing in inches,

and end using milli-meters.

Learn how to draw all kinds of curves from points to interpolated curves. There are many options you need to know. Pay atten-tion to options such as vertical construction planes or around the curve.

Learn how to draw all kinds of curves.


Chapter 4 Curve Tools.

Chapter 4 Curve Tools.

Notes: There are many editing tools that would make your drawing more precise. Every time you import a drawing from another program, you may have to edit a few things here and there. Get familiar with all the tools. You will learn soon you cannot work without them

Curve Tools Key things to remember.

There are many options for editing curves in

Rhino 4.0. You should pay attention to those

options since a good 2D drawing may have few

spots where you need to fix or edit them. Try few

of them and find out by yourself how powerful these

tools are. Try for example the new

Blend (BlendCrv) or Curve from Two

Views (Crv2View).

Learn how to how to edit all your curves in Rhino 4.0. There are many editing tools that would help you manipu-late your model. Mostly all of them work in both 2D and 3D.

Learn how to edit and manipulate your curves.


Chapter 5: Layers.

Chapter 5: Layers.

Notes: Find the status bar, and click the layer shortcut icon. You will see the layer pop-up. You can checkbox the name of any layer and set that layer as the current. Note also that you have to define the type of lines before you use them with the layer pop-up.

Layers Key things to remember.

There are many options for layers in Rhino 4.0.

One of the best ones, and recently added is the

possibility to make sub-layers. This is a great

way to organize all your layers by groups. Also, pay attention to how you name your layers. It

helps to make all the layers with color and line-types. Save them as a

template so they can be used over

and over again.

Rhino 4.0 layers work like CAD layering systems. By creating objects on different layers, you can edit and view related por-tions of a model separately or as a com-posite.

Learn how to organize your drawings with the help of layers.


Chapter 6: Precision Modeling.

Chapter 6: Precision Modeling.

Notes: Rhino uses a fixed Cartesian coordinate system called the world coordinate system (WCS), based on three axes (the X-, Y-, and Z-axes) that define location in three dimensional space. Also, you will be able to find out many features there are from your model such as areas and volumes.

Precision Modeling Key things to remember.

Precision modeling is the key to be able to proto-type your models in real life. Pay attention to the tolerance of your draw-ings before your start.

You can change the toler-ance after you start,

but objects created before that change

still have the old tolerance value. So,

set the units and tolerance before

you start to draw.

So far you have been drawing imprecise lines. Now you will try drawing lines in specific places. To do so, you need to know how to use coordinates. Precision is the name of the game.

Learn how to model with precision.


Chapter 7: Transform.

Chapter 7: Transform.

Notes: There are other toolbars inside the main transform toolbar. One of them is the Scale Toolbar. Another toolbar that you will use all the time is the Array toolbar. There are some exercises that show how the Array command works with History too.

Transform Key things to remember.

Transform brings new tools to Rhino 4.0.

Among them are the new UDT tools. Known as Uni-versal Deformation Tools.

You should get familiar with each one of the UDT

tools. Also, many of the transform tools work

along with history. There-fore, it is important to know which com-

mands allow you to work with history.

After you create objects, you will learn how you can move and edit them to produce complex and detailed variations. Try all the new UDT tools in Rhino 4.0

Learn how to modify objects with a wide range a tools.


Chapter 8: Document properties & Rhino options.

Chapter 8: Document properties & Rhino options.

Notes: It is very fun to use the stereo glasses after you learn how to create a display mode using the Rhino options. The glasses that Rhino Visual Tips 4.0 comes with have the Red glass to the left, and the Blue glass to the right. There are three 3DM files that you can open and see for yourself with your stereo glasses.

Document properties. Key things to remember.

Keep in mind that all the changes you make to

Document Properties will be saved inside the 3DM file, but all the changes that you make to Rhino

Options, like Color, Key-board, Mouse, General,

Files, View, etc affect only your computer. You

can export all your Rhino Options to a file so

that you can import them to another computer easily.

After you create objects, you will learn how you can change the display mode of each one. You can view them as wireframe, shaded or ghosted.

Learn how to modify Rhino options and document properties.


Chapter 9: Surfaces & Surface Tools

Chapter 9: Surfaces & Surface Tools

Notes: Surfaces can be created using other surfaces as an input. For example, you have the surface from Curve Network. Network creates a surface from a network of smooth curves. Rhino handles curves that do not touch exactly. Curve Network can also use the edges of other surfaces as input. Try it out.

Surfaces & Surface Tools Key things to remember.

A surface is like a rectan-gular stretchy rubber

sheet. The NURBS form can represent simple

shapes, such as planes and cylinders, as well as

free-form, sculptured surfaces using a single surface representation.

All surface creation com-mands in Rhino 4.0 result in the same object: a NURBS surface.

Rhino 4.0 has many tools for con-

structing surfaces directly or from ex-

isting curves.

Learn a variety of surface constructions, including free-form surfaces fit to points, tapered off-set surface constructions, rolling-ball fillets and blend surfaces.

Learn how to draw surfaces and edit them.


Chapter 10: Solids and Solid Tools

Chapter 10: Solids and Solid Tools

Notes: Booleans provide a method of combining surfaces. They work best on closed solids, but can be used for other surfaces. The Boolean operations add, subtract, and intersect surfaces, polysurfaces and solids. There is another great

toolbar with many new tools to edit solids, called the Solid Editing toolbar. Please, try those commands too.

Solids & Solid Tools Key things to remember.

A polysurface consists of two or more surfaces that

are joined together. A polysurface that encloses

a volume of space defines a solid. Some Rhino

commands for creating solid primitives create

polysurface solids. Boxes, cones, truncated cone s and cylinders are exam-ples of polysurface

solids.

Always remember that a solid is a surface or polysurface that encloses a volume. Sol-ids are created anytime a surface or polysurface is completely closed.

Learn how to draw solids and edit them.


Chapter 11: Meshes and Mesh Tools

Chapter 11: Meshes and Mesh Tools

Notes: There is not an easy way to convert a mesh model into a NURBS model. The information that defines the objects is completely different. However, Rhino has a few commands for drawing curves on meshes and extracting vertex points

and other information from mesh objects to assist in using mesh information to create NURBS models.

Mesh and Mesh Tools Key things to remember.

While Rhino can create, import and display poly-

gon mesh geometry, Rhino is now capable to

model and edit solids and meshes at the same

time. You can use com-mands such as mesh trim, split, and mesh

booleans. One of the best commands that come s

with Rhino 4.0 is Offset mesh. As

you can see from the photo on the

left, it not only off-sets the surface, but also can create a

solid.

Rhino 4.0 provides us with many new tools that enable us to edit and transform mesh objects. It also provides tools that let you repair open meshes.

Learn how to draw meshes and edit them, even with solids.


Chapter 12: Curves from objects.

Chapter 12: Curves from objects.

Notes: Open the dimension toolbar. Inside that toolbar you will also find the command called Make 2D. You can find it by the black cube with the pencil. You can create a 2D drawing from a 3D model. This command is found in both toolbars, the Dimension and Curve from Objects.

Curves from objects. Key things to remember.

One of the best features of Rhino 4.0 is History. Now you will be able to

Loft some curves, section the surface and edit the

original curves that were used to create the loft. The change is instant!,

since History will let you edit the original curves and see the change al-most in real time.

Learn how to take advan-tage of history when you use some commands from the Curve From Object tool-bar. Commands like Inter-section and Project can be used with history.

Learn how to get curves and surfaces from other objects.


Chapter 13: Dimensions.

Chapter 13: Dimensions.

Notes: The dot command places a text dot. Dots are always parallel to the view. There isn’t control for the dot size or shape. Dots are display in the layer color. Dot sizes are constant on the screen. Double click it to edit the content of the dot.

Dimensions. Key things to remember.

Rhino 4.0 can provide the ability to add notation to

your model in the form of dimensions, leaders, and

text blocks. These appear as objects in the model. A different form of nota-tion, the annotation dots and arrowheads, always

display facing towards the view plane. Do not

forget that now you can Double Click the text to edit it.

Learn how to create and save your own dimension styles. You will save a lot of time in the future by having these styles ready. New in Rhino 4.0 are the Ordinate dimensions. Try those too.

Learn how to dimension and annotate your drawings.


Chapter 14: Print and Layouts.


Notes: Now it is easier than ever to create detail views before you print. You can scale each view and even shade or render the view. You can add logos and bitmaps to our drawings and print them too. You can even select the scale to each view individually.

Print and Layouts. Key things to remember.

Rhino 4.0 comes with many new tools to make printing technical draw-ings much easier. With

the help of the sheet lay-out toolbar, you can or-ganize your views at a

time. Print them to scale and even add photos to

your technical drawings. If you are organized and

create a template with the right di-

mensions and lay-ers, you will be ready to print at

any moment.

Learn how to set up your drawings before you print them to any scale. You can have many detail views in your print layout.

Learn how to layout and print to scale your drawings.


Chapter 15: Render and Lights.


Notes: The Rhinoceros Render window contains a File menu that lets you save the rendered image as a bitmap file. From the Render window File menu, you can also copy the image to the Windows Clipboard and then

paste it directly into another application.

Render and Lights. Key things to remember.

Objects will render white until you add color, high-light, texture, transpar-ency, or bumps. These

attributes are controlled through the Properties window, and Material

page. If you want to cre-ate photo-realistic ren-

derings, use a full-featured rendering pro-gram, such as Fla-

mingo, V-Ray, Bra-zil etc.

In addition to shade pre-views, Rhino provides full-color rendering with lights, transparency, shows, tex-tures, and bump mapping. Explore and learn all these possi-bilities. Lear also to change the setting of the mesh.

Learn how to setup your lights and render your models.
