Introduction

Since its infancy, just a decade ago, the emerging field of digital design has

revolutionized the thought process of designers and allowed teams of talented individualsto collaborate faster and with far more precision than ever before. Using the Internet,

seamlessly across the U.S. and the Globe, oceans of new talent are being incorporatedinto production.

The emerging technology of Computer-Aided-Drafting & Design has offered both two-

and three-dimensional modelers new ways of thinking and has clearly challenged the

traditional minds, requiring them to utilize new and digital tools to bring ideas to reality.

Today with its design-centric mindset, AutoCAD is offering designers, drafters,

engineers, architects, interior designers, and students tools that allow for speed, precision,consistency and legibility, all in a collaborative environment. With over 3.5 million users

around the world, the leading drafting software has set the tone for CAD standards,

giving the well trained users mobility and flexibility.

Advanced AutoCAD

2007: The Academic Solution is a set of step-by-step AutoCAD

tutorials designed specifically for academia. This book is a continuation ofIntroduction

to AutoCAD 2007(or 06), The Academic Solution. Whether they are used as astandalone or with other standard AutoCAD textbooks, you will find these advanced

tutorials to be well-structured, informative, and easy to follow. In order to maximize

your success, it is best to follow the procedure step by step and not skip any instructions.It is also recommended to have theIntroduction to AutoCAD 2007(or 06)The Academic

Solution textbook available for reference purposes.

The Text consists of 14 chapters. Every chapter corresponds to and is equivalent to aweek of instructions and assignments for the advanced CAD course. Some chapters

group two distinct topics together to accommodate for a week of instructions. For a

recommended approach to progressing through the text, refer to the flowchart on the next

page or consult with your instructor. The book is best followed with all assignmentsaccomplished using the same computer and/or network.

As you reach the end of the book, you should feel confident in your knowledge of thesoftware because you are considered to be an advanced user. Keep in mind that practice

is crucial for retaining the knowledge, making you an efficient AutoCADuser.

Terminology Used in This Book

Bold A word in bold letters signifies that it is an AutoCAD specific term or that it is a

very specific item (i.e., a specific color, Object, or name).

Terminology

Bold Italics A number that is displayed in both bold and italic signifies that it is to beentered by means of the keyboard.

By doing the following: A sentence ending with the term "by doing the following:"signifies that you areabout to be given step-by-step, bulleted instructions as tohow to perform a specific operation for the first time.

Command: - The Command Prompt is the location where you instruct AutoCAD to

perform a specific task. For example, typing in "Erase" at the Command

Prompt and then pressing the Enter key, instructs AutoCAD to erase one or a

group of Objects. Also note that in AutoCAD, with very few exceptions, the

cursor is always automatically positioned at the Command Prompt.

Terminology

Pointer device Most computers are configured for a mouse, however, you may be using

a pen tablet, a digitizer or any other device which may serve the same function.

Click Refers to picking the "left" Pointer Button of the mouse. If the right pointerbutton is to be selected, you will be specifically instructed to right-click.

Double-click Indicates clicking a pointer button on your mouse twice without pausingor hesitating between clicks.

Drag Refers to pressing down the left pointer button while moving/dragging the mouse

to a new location and then releasing the button.

ENTER Refers to pressing the Enter key on the keyboard. As you will see, any

keyboard entry at the Command Prompt will require an ENTER. However inthe later Chapters, at times it may be expected of you to ENTER after a

Command entry without specific instructions.

Note: A note generally furnishes you with information and explains concepts but doesnot require you to take any action.

Pick Refers to left clicking within the Drawing space(i.e., Pick Circle C1, refers to leftclicking on Circle C1.) The terms Pick and Select are interchangeable.

Select Refers to picking a menu item/tool or a pre-existing Object by clicking on itusing the mouse (i.e., "Select Erase" means that you should select the Erase

Icon/tool as opposed to typing the CommandErase).


16/63

x

Toggle Refers to a setting that has a switch mode (i.e., On, Off). There are differentmethods of toggling:

1. Function keys. The function keys are usually located along the top of yourkeyboard and are identified by the letter F and a number. Each function key

is assigned to a specific AutoCAD function. For instance, pressing F9 willToggle your Snap settings to On/Off.

2. Control Keys. Control keys are another way of allowing for shortcuts.Control keys are used by holding the CTRL key, and then pressing another

key. For instance, CTRL+2 will toggle the DesignCenter.

3. Toggleswitches. Many AutoCAD settings can also be Toggled from dialogboxes as shown below. As an example, as the Endpoint OSnap mode Toggle

is selected, a check mark appears and the setting is Toggled to on as shownbelow.

4.

Toggle Buttons. Buttons located in the Status Line are another way oftoggling certain settings. There are eight buttons located in the Status Line

that can be Toggled by clicking on the buttons with the pick button. When the

button appears depressed it is On, otherwise it is Off. For instance, in the firstimage shown below Snap is Toggled to the offposition. The second image

shows Snap Toggled On. These buttons will be covered in more detail later.

User-Specified This term is used when requesting a non-specific entry where the exactsize or location for Drawing an Object (or a group of Objects) is flexible, i.e.,"Create a Circle in a User-specified location as shown below" means that you can

approximate the size and location similar to a given diagram.


17/63

xi

Other Terminology and Information

CAD: A general term meaning Computer Aided Drafting or sometimes Computer Aided

Design. This term is not specific to AutoCAD.

CADD: A general term meaning Computer Aided Design and Drafting.

CAD Station: A computer station that has CAD software installed (in this case

AutoCAD) and preferably has other peripherals such as a plotter and sometimes adigitizer. The advantages of using a CAD station over manual drafting are basically

speed, repeatability, accuracy, and easy editing.

AutoCAD: With over 3.5 million users, this AutoDesk product is currently the most

widely used CAD software in the industry.

Commercial Version: This is the version of the CAD program that is purchased forprofessional design and drafting and is for commercial use. In other words, you may use

the license for profit.

Educational Version: This version is available to students who are enrolled in three or

more credits at a degree-granting educational institution or those who are enrolled at anine-month certificate-granting program. The Student Version is also available to

registered K-12 students who can confirm current enrollment. Although the Educational

software has the same functionality as the commercial, it can not be used for the purposeof profit.

Purchasing AutoDesk

products: AutoDesk software, such as AutoCAD, Inventor,Rivet, 3ds MAX, Civil 3D and many others can be purchased from AutoDesk directly or

through Authorized AutoDesk Resellers around the country. For more information, youcan go to the AutoDesk estore at http://estore.autodesk.com where you can also locate

resellers near you. You can also check with your school's bookstore.

Folders

In this section, you will create all the necessary Folders for your assignments. As

you already know, Folders are where files, such as Drawings, are saved. Many teaching

institutions use the common practice of automatically creating the student folders usingstudents' names and/or ID numbers. These student folders are often placed on a network

drive such as F:, T:, or H: as opposed to the Local Disk (C:). An example of a folderand its associated path is T:\Engineering_Technologies\Smith_David_02, where a

common folder such as David Smith 02 is created on the T: drive under the Engineering

Technologies folder as shown below.

In the event that you are not clear on how to create folders, or where your folderresides or is to be created, consult with your instructor. In this case, it is also

recommended that you review the File Management section ofAppendix A to learn tocreate a New Folders and RenameFolders, etc.

Many teaching institutions install Computer Security software in their computer

labs. This is to improve system stability, protect against viruses, avoid Internetdownloads, etc. In many cases, this type of software does not allow for your AutoCAD

Drawing files to reside/stay on the Local Disk (C:). It is for this reason (and more) that

you should save your files to a specific Drive and Folder as designated by yourInstructor.


22/63

4

The instructions below will help you in creating your Main folder (from this point

on referred to as My_CAD_Folder). This exercise will create your folder in the

Documents and Settings folder of the LocalDisk(C:). However, as mentioned before,

you may already have a main folder assigned to you so that you only have to create your

subject folders inside the main folder.

Caution: If you have a folder assigned to you already, skip to page 6 to create the

subject folders. Consult with your instructor as necessary.

1. Create your main Folder by doing the following:Creating Folders

From the Microsoft WindowsInterface, select Start then My Computeras shown below.

At the My Computer window, double-click on Local Disk (C:) andselect the DocumentsandSettings folder (or your drive as designated byyour instructor).


23/63

Chapter One 5

From the Menu Bar, select File, then New, then Folder as shown below.{A NewFolder appears. It is highlighted, and the cursor is located to the

right of the name. Since the name is already highlighted, you don't need

to back space.}

Type in the new name:My_CAD_Folder and thenENTER. Double-click on the folder My_CAD_Folder folder. {You are inside the

folder. The name appears at the Address field, and it is obviouslyempty.}

Select the Back button. {It will take you "back" out of the folder and tothe Documents and Settings folder of the Local Disk (C:).}

Renaming Folders

Right-click on the My_CAD_Folder folder and select Rename. {Thename is highlighted.}

Type in your last name followed by your first name, i.e., SmithDavid ENTER. {The folder is renamed to your name.}

Note: From this point on, for the sake of consistency, the book will refer to your main

folder as your My_CAD_Folder.


24/63

Subject Folders

Once you have your My_CAD_Folder folder such as T:\Engineering_

Technologies\Smith_David_02, you need to create 18 folders that fall inside your main

folder. The 18 folders include 16 topics and two more folders for your symbol libraryand Templates. Do not skip the instructions below as these folders are needed to

continue through the tutorials.

Double-click on your My_CAD_Folder {Your My_CAD_Folder windowappears and you are placed inside your folder.}

Select File, New, and then Folder again. As the highlighted New Folderappears, type in the name Review_Material and thenENTER. {The new

Folder is created.}


25/63

Chapter One 7

Repeat this process to create the remaining 17 folders. Name these foldersSymbols, Templates, Attributes, Polylines_and_Splines, Digitizing,

External_References, Three_Dimensions, Customization,

Dynamic_Blocks, Data_Exchange, Slideshow, Internet, Isometric,

Sheet_Sets, DataBase, Express Tools, and AutoLISP. Since this is arepetitive process, you may use the key stroke sequence Alt+ F, then W,and then F to create each folder. Note that it is not critical to use the

underscore "_" symbol when naming your folders. However, for reasonsstated later, the Slideshow folder name should be a single word having no

spaces.

The image below displays the list of folders in alphabetical order, not inthe sequence used in the course.

Close the above window since you are about to launch AutoCAD.

Chapter One 9

Select the SaveAs button. {The Save Drawing As window appears.} In the File of type drop down, select AutoCAD Drawing Template

(*.dwt) as shown below.

In the File name text field, name the file My Template Model Space Asize_ _ _ where the three blanks are your initials.

In the Save in drop down, select your Templates folder located insideyour main folder.

Select the Save button. {The TemplateDescription dialog box appears.} Leave the description as is, and select OK. From the Menu Bar, select File and then Exit AutoCAD.

Note: Keep in mind that opening a Template file by selecting File, Open and changingthe File of type to *.dwt is interpreted by AutoCAD as if you plan to modify your

Template rather than use it to start up a new Drawing. So in the future, unless you

intend to update or modify a Template, do not use the Open option from the File MenuBar to Open a Template file, but rather use the File, New option to begin a new Drawing

file. Later in the chapter, you will also learn how to import a Template into an already

existing Drawing.


28/63

Create a Template (Paper Space)

In Chapter 12 of Volume I, you learned about Layouts and PaperSpace, where

you created an A size Template for use in PaperSpace. The procedure below repeats

that exercise of creating a Template to be used throughout this book.

1. Create a Drawing Template in Paper Space by doing the following: Launch AutoCAD and begin a new blank Drawing. In the event that you

are asked to choose a Workspace, select AutoCADClassic and then OK.

Set your Units to Decimal with Precision set to two decimal places(0.00).

Make sure that from the Status Line, Snap, Grid, Orth, Polar, Osnap,Ducs, and Dyn are set to Off.

Create a Layer named Title block, and set it as the Current layer. Click on the Layout1 Tab as shown below. {An A (letter) size paper is

displayed and you are placed in Paper Space as shown by the

Paper/Model toggle of the Status Line.}

Erase the default Viewport shown in the form of a rectangle. A newViewport will be created that is more suitable to your My Template

Paper SpaceA size_ _ _.dwt Template.


29/63


30/63

12

To toggle to ModelSpace, double-click within the Viewport area. {TheViewport is displayed in bold, verifying that you are in ModelSpace.}

From the Status Line, select the Model button to switch back to PaperSpace as shown below.

Select the SaveAs button. {The Save Drawing As window appears.}

In the File of type drop down, select AutoCAD Drawing Template(*.dwt).

In the File name text field, name the file My Template Paper Space Asize_ _ _ where the three blanks are your initials.

In the Savein drop down, select your Main Folder, as designated by yourinstructor and then select Templates.

Select the Save button. {The TemplateDescription dialog box appears.} Leave the description as is, and select OK. From the Menu Bar, select File and then Exit AutoCAD.


31/63

Chapter One 13

Creating a Symbol Library

You are about to create a library of symbols as shown below by the 9 Objects. In

creating these symbols, you will exercise your technique of geometric construction while

keeping precision in mind. Note that the symbols you are about to create will be usedthroughout the textbook. To avoid lost time, save your progress frequently. Although the

symbols you are creating are Architectural, the techniques you are learning can beapplied to a variety of fields such as Mechanical, Industrial, Civil, etc.

1. Launch AutoCAD to begin a new blank Drawing. You will use your PaperSpaceTemplate later in the Chapter. In the event that you are asked to choose a

Workspace, select AutoCAD Classic and then OK.

2. Set Units to Architectural and Precision to 1/16.3. Set Limits to 0',0' by24',16' and then ZoomAll.4. Make sure that Ortho, Polar, Osnap, Otrack, Ducs, and Dyn are set toOff.5. Use the Rectangle tool to create a rectangular border having the same corners as

your limits.


32/63

14

6. Set Snap and Grid by doing the following: In the Status Line, right-click on the Grid Button and from the shortcut

menu, select Settings.

As the Drafting Settings dialog box appears, set both Snap and Grid to6". Toggle both Snap and Grid to On. Ensure that the Adaptive Grid setting is toggled Offas shown below.

Note: Adaptive grid allows for an automatic change in grid settings based on the current

zoom factor. As an example, if you zoom in/out noticeably, the system will change to a

Redefining Blocks

Knowing that in a design environment, change is inevitable, and that Drawings

and symbols are revised frequently, AutoCAD allows for simple and practical editing of

Blocks. The editing of a Block is referred to as Redefining a Block.

1. Redefine a Block by doing the following: Open the My_Symbols_Library _ _ _.dwg Drawing file from your

Symbols folder.

Make the following modifications to the Desk symbol:Fillet the corners of the Desk using a Radius of2.In the case of a

rectangle, you can use the Polyline option of the Fillet Command to

Fillet all 4 corners in one selection.

In the upper left corner of the Desk, 6" from the edge, create a Circlehaving a Radius of1.5".

Offset the Circle to the inside by 0.25.

Mirror the two Circles about the center of the desk vertically, as

shown below.

In this exercise, you will incorporate the updated symbols into the Office

Drawing. As demonstrated in this assignment, the first time a Block is Inserted, the

WBlock file will be used. Once the Block is Inserted into the Drawing, it resides in the

Drawing and can be addressed locally. Finally, the Drawing will be plotted using a

newly created Layout by means of a Template.

Open the Office with Furniture_ _ _ Drawing. From the Draw toolbar, select the InsertBlock tool. {The Insert dialog

box appears.}

Click on the Browse button. From the list of Drawing files, select Desk.dwg and then select Open and

then OK. {The Dialog box appears, informing you that the Block is

already defined and gives you the option to update Block definition.}
