COMPUTER AIDED ELECTRICAL DRAWING

PREFACE

This book provides a step-by-step introduction to AutoCAD with commands presented in the context of each chapter. In eleven clear and comprehensive chapters, authors guide readers through all the important commands and techniques in AutoCAD 2018, for 2D drawing to complete electrical engineering schematics and finally finishing with plotting output. In each lesson, the author provides step-by-step instructions with frequent illustrations showing exactly what appears on the AutoCAD screen. Later, individual steps are no longer provided, and readers are asked to apply what they have learned by completing sequences on their own. A carefully developed pedagogy reinforces this cumulative-learning approach and supports readers in becoming skilled AutoCAD users. Tutorial Guide to AutoCAD 2018 begins with the Getting Started chapters that include information to get readers of all levels prepared for the tutorials. The author includes tips that offer suggestions and warnings as you progress through the tutorials. Key Terms and Key Commands are listed at the end of each chapter to recap important topics and commands learned in each tutorial. Also, a glossary of terms and Commands Summary list the key commands used in the tutorials. Each chapter concludes with end of chapter tutorial providing challenges to a range of abilities in mechanical, electrical, and civil engineering as well as architectural problems.

03 CREATING A NEW DRAWING

AutoCAD and AutoCAD LT create a blank drawing upon startup, but it’s a good idea to select the drawing template that you want to use at startup and not rely on the one that AutoCAD or AutoCAD LT creates for you. To create a new drawing, follow these steps:

1. Click Start Drawing.For new drawing, click Start Drawing

A new drawing is created for you based on the drawing template selected.
