Index I-1

Preface
AutoCAD 2016
AutoCAD, developed by Autodesk Inc., is the most popular PC-CAD system available
in the market. Today, over 7 million people use AutoCAD and other AutoCAD-based
design products. 100% of the Fortune 100 firms and 98% of the Fortune 500 firms are
Autodesk customers. AutoCAD’s open architecture allows third-party developers to
write application software which has significantly added to its popularity. For example,
the author of this book has developed a software package “SMLayout” for sheet metal
products that generates a flat layout of various geometrical shapes such as transitions,
intersections, cones, elbows, tank heads, and so on. Several companies in Canada and
United States are using this software package with AutoCAD to design and
manufacture various products. AutoCAD also facilitates customization that enables the
users to increase their efficiency and improve their productivity.

The AutoCAD 2016: A Problem-Solving Approach, Basic and Intermediate
textbook contains a detailed explanation of AutoCAD commands and their applications
to solve drafting and design problems. Every AutoCAD command is thoroughly
explained with the help of examples and illustrations. This makes it easy for the users to
understand the functions and applications in the drawing. After reading this textbook,
you will be able to use AutoCAD commands to make a drawing, dimension a drawing,
apply constraints to sketches, insert symbols as well as create text, blocks and dynamic
blocks.
The book also covers basic drafting and design concepts that provide you with the

essential drafting skills to solve the drawing problems in AutoCAD. These include
dimensioning principles, and assembly drawings. While going through this textbook,
you will discover some new unique applications of AutoCAD that will have a significant
effect on your drawings. In addition, you will be able to understand why AutoCAD has
become such a popular software package and an international standard in PC-CAD.

Formatting Conventions Used in the Textbook
Refer to the following list for the formatting conventions used in this textbook.
• Command names are capitalized and written in boldface letters.
• A key icon appears when you have to respond by pressing the ENTER or the

www.EngineeringBooksPDF.com


RETURN key.
• Command sequences are indented. The responses are indicated in boldface. The
directions are indicated in italics and the comments are enclosed in parentheses.
• The methods of invoking a tool/option from the Ribbon, Menu Bar, Quick Access
Toolbar, Tool Palettes, Application menu, toolbars, Status Bar, and Command
prompt are enclosed in a shaded box.
Ribbon: Draw > Line
Menu Bar: Draw > Line
Tool P alettes: Draw > Line
Toolbar: Draw > Line
Command: LINE or L
Example: The MOVE command
Command: MOVE

Select object: G
Enter group name: Enter a group name (the group name is group1)

Naming Conventions Used in the Textbook
Tool
If you click on an item in a toolbar or a panel of the Ribbon and a command is
invoked to create/edit an object or perform some action, then that item is termed as
tool.
For example:
To Create: Line tool, Circle tool, Extrude tool
To Edit: Fillet tool, Array tool, Stretch tool
Action: Zoom tool, Move tool, Copy tool
If you click on an item in a toolbar or a panel of the Ribbon and a dialog box is
invoked wherein you can set the properties to create/edit an object, then that item is
also termed as tool, refer to Figure 1.
For example:
To Create: Define Attributes tool, Create tool, Insert tool
To Edit: Edit Attributes tool, Block Editor tool

www.EngineeringBooksPDF.com


Figure 1 Various tools in the Ribbon

Button
If you click on an item in a toolbar or a panel of the Ribbon and the display of the
corresponding object is toggled on/off, then that item is termed as Button. For
example, Grid button, Snap button, Ortho button, Properties button, Tool Palettes
button, and so on; refer to Figure 2.

Figure 2 Various button displayed in the Status Bar and Ribbon
The item in a dialog box that has a 3d shape like a button is also termed as Button. For

example, OK button, Cancel button, Apply button, and so on.

Dialog Box
The naming conventions used for the components in a dialog box are mentioned in
Figure 3.

www.EngineeringBooksPDF.com


Figure 3 The components of a dialog box

Drop-down
A drop-down is the one in which a set of common tools are grouped together. You can
identify a drop-down with a down arrow on it. These drop-downs are given a name
based on the tools grouped in them. For example, Circle drop-down, Fillet/Chamfer
drop-down, Create Light drop-down, and so on; refer to Figure 4.

www.EngineeringBooksPDF.com


Figure 4 The Circle, Fillet/Chamfer, and Create Light drop-downs

Drop-down List
A drop-down list is the one in which a set of options are grouped together. You can set
various parameters using these options. You can identify a drop-down list with a down
arrow on it. To know the name of a drop-down list, move the cursor over it; its name
will be displayed as a tool tip. For example, Lineweight drop-down list, Linetype
drop-down list, Object Color drop-down list, Visual Styles drop-down list, and so on;
refer to Figure 5.
