The AutoCAD 2019: A Problem-Solving Approach, Basic and Intermediate, 25th Edition textbook contains a detailed explanation of AutoCAD commands and their applications to solve drafting and design problems. In this textbook, every AutoCAD command is thoroughly explained with the help of examples and illustrations. This makes it easy for the users to understand the functions of the tools and their applications in the drawing. After reading this textbook, the user 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 such as dimensioning principles and assembly drawings that equip the users with the essential drafting skills to solve the drawing problems in AutoCAD. While reading this textbook, you will discover some new tools introduced in AutoCAD 2019 such as DWG Compare, Save to Web & Mobile, and Shared Views that will enhance the usability of the software.

Some of the features of this text book are:

• Comprehensive textbook consisting of 24 chapters that are organized in a pedagogical sequence.
• Detailed explanation of all commands and tools.
• Summarized content on the first page of the topics that are covered in the chapter.
• Hundreds of illustrations for easy understanding of concepts.
• Step-by-step instructions to guide the users through the learning process.
• More than 30 real-world mechanical engineering designs as examples.
• Additional information throughout the book in the form of notes and tips.
• Self-Evaluation Tests and Review Questions at the end of each chapter to help the users assess their knowledge.
• Technical support by contacting [email protected].

Editing Sketched Objects-I

Learning Objectives

After completing this chapter, you will be able to:

• Create selection sets using various object selection options

• Use the Move and Copy tools

• Stretch

• Array

• Rotate

• Mirror

• Scale

• Lengthen

• Measure

• Divide

• Blend

CREATING A SELECTION SET

For most of the tools, the default object selection method is to use the pick box (cursor) and select one entity at a time. You can also click in blank area and select objects by using the Window option or the Crossing option. In Chapter 2, these two options were discussed. The other options used for selection are listed below and are discussed in this chapter.

Last

CPolygon

Add

Undo

Previous

SUbobject

Fence

Box

SIngle

ALL

Group

AUto

WPolygon

Remove

Multiple

Object

Last

This option is used to select the last drawn object, which is partially or fully visible in the current display. This is the most suitable option to select the last drawn object while editing it. Keep in mind that if the last drawn object is not in the current display, the last drawn object in the current display will be selected. Although a selection can be made using the Last option, only one object is selected at a time. However, you can use the Last option a number of times but it will require you to start the command again. You can use the Last selection option with any tool that requires the selection of multiple objects (for example, Copy, Move, and Erase). To select the last drawn object by using this option, invoke a particular tool, and then enter LAST or L at the Select objects prompt to use this object selection method.

Exercise 1 Erase

Draw the profile shown in Figure 5-1(a) by using the Line tool. Then, use the Last option of the Erase tool to erase the three most recently drawn lines to obtain Figure 5-1(d).

Figure 5-1 The initial and final profiles for Exercise 1

Previous

The Previous option is used to select the objects that were selected in the previous selection set. Generally, AutoCAD saves the previous selection set; therefore, you can select those objects again by using the Previous option, instead of invoking the same selection method. In ...
