Download or read book AutoCAD 2024 Instructor written by James A. Leach and published by SDC Publications. This book was released on with total page 1263 pages. Available in PDF, EPUB and Kindle. Book excerpt: • In depth coverage of AutoCAD’s commands and features • Chapters are structured around related commands • Starts with fundamental commands and progresses to more specialized applications • An ideal reference guide for users at all levels • Well suited for a two or three course sequence • Includes introductory videos and bonus chapters on dynamic blocks and express tools This book is your AutoCAD 2024 Instructor. The objective of this book is to provide you with extensive knowledge of AutoCAD, whether you are taking an instructor-led course or learning on your own. AutoCAD 2024 Instructor maintains the pedagogy and in-depth coverage that have always been the hallmark of the Leach texts. As the top-selling university textbook for more than a decade, the AutoCAD Instructor series continues to deliver broad coverage of AutoCAD in a structured, easy-to-comprehend manner. AutoCAD 2024 Instructor is command-oriented, just like AutoCAD. Chapters are structured around related commands, similar to the organization of AutoCAD’s menu system. The sequence of chapters starts with fundamental drawing commands and skills and then progresses to more elaborate procedures and specialized applications. The writing style introduces small pieces of information explained in simple form, and then builds on that knowledge to deliver more complex drawing strategies, requiring a synthesis of earlier concepts. Over 2000 figures illustrate the commands, features, and ideas. AutoCAD 2024 Instructor is an ideal reference guide, unlike tutorial-oriented books where specific information is hard to relocate. Because these chapters focus on related commands, and complete coverage for each command is given in one place, the commands, procedures, and applications are easy to reference. Tabbed pages help locate tables, lists, appendices, and the comprehensive index. What makes this book unique? • In depth coverage of AutoCAD 2024 commands and features • Command Tables indicate where to locate and how to start each command • TIP markers in the margin provide important tips, notes, reminders, and short-cuts • Complete chapter exercises with many multi-chapter “REUSE” problems • Well suited for a two or three course sequence Online Resources Your purchase of AutoCAD 2024 Instructor includes two free exclusive bonus chapters and introductory videos that are available by redeeming the unique access code found on the inside of the front cover.

Book Technical Drawing 101 with AutoCAD 2022

Download or read book Technical Drawing 101 with AutoCAD 2022 written by Ashleigh Congdon-Fuller and published by SDC Publications. This book was released on 2021-07 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Blends technical drawing and an introduction to AutoCAD 2022 • Covers both mechanical and architectural projects • Twenty six hours of video instruction is included with each book • Drafting theory is incorporated throughout the text • Designed to be used in a single semester, instructor led course • Each chapter contains key terms, unit summaries, review questions and drawing projects Technical Drawing 101 covers topics ranging from the most basic, such as making freehand, multiview sketches of machine parts, to the advanced—creating an AutoCAD dimension style containing the style settings defined by the ASME Y14.5-2009 Dimensioning and Tolerancing standard. But unlike the massive technical drawing reference texts on the market, Technical Drawing 101 aims to present just the right mix of information and projects that can be reasonably covered by faculty, and assimilated by students, in one semester. Both mechanical and architectural projects are introduced to capture the interest of more students and to offer a broader appeal. The authors have also created extensive video training (176 videos, 26 hours total) that is included with every copy of the book. In these videos the authors start off by getting students comfortable with the user interface and demonstrating how to use many of AutoCAD's commands and features. The videos progress to more advanced topics where the authors walk students through completing several of the projects in the book. The CAD portion of the text incorporates drafting theory whenever possible and covers the basics of drawing setup (units, limits, and layers), the tools of the Draw, Modify, and Dimension toolbars, and the fundamentals of 3D modeling. By focusing on the fundamental building blocks of CAD, Technical Drawing 101 provides a solid foundation for students going on to learn advanced CAD concepts and techniques (paper space, viewports, xrefs, annotative scaling, etc.) in intermediate CAD courses. In recognition of the diverse career interests of our students, Technical Drawing 101 includes projects in which students create working drawings for a mechanical assembly as well as for an architectural project. We include architectural drawing because our experience has shown that many (if not most) first-semester drafting students are interested in careers in the architectural design field, and that a traditional technical drawing text, which focuses solely on mechanical drawing projects, holds little interest for these students. The multidisciplinary approach of this text and its supporting materials are intended to broaden the appeal of the curriculum and increase student interest and, it is hoped, future enrollments.

Book Up and Running with AutoCAD 2013

Download or read book Up and Running with AutoCAD 2013 written by Elliot J. Gindis and published by Academic Press. This book was released on 2012-12-31 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up and Running with AutoCAD 2013 by Elliot Gindis is an easy-to-learn introduction to AutoCAD featuring step-by-step instructions that explain both the why and the how for using this industry standard software package. The book strips away complexities, both real and perceived, and reduces AutoCAD to easy-to-understand basic concepts. All concepts are explained first in theory, and then shown in practice, helping the reader understand what it is they are doing and why, before they do it. The book is divided into three parts, guiding students through the subject matter from the beginning stages of using the software through advanced AutoCAD, including 3D features. Chapters deal with topics such as: layers, colors, linetypes, and properties; text, Mtext, editing, and style; blocks, Wblocks, dynamic blocks, groups, and purge; importing and exporting data; Boolean operations; Dview, walk and fly, animation, and action recording; and lighting and rendering. Also included is an extensive Appendix for each part, detailing additional useful CAD-related information not often found in other text books. In addition, the book contains supporting graphics (screen shots); a summary with a self-test section at the end of each chapter; drawing examples and exercises; and two running "projects" that the student works on as he/she progresses through the chapters . This book will appeal to beginner through advanced users of AutoCAD; architectural engineers, drafting, civil/construction engineers, and mechanical engineers; and students taking drafting/engineering drawing courses in engineering and engineering technology programs. Strips away complexities, both real and perceived and reduces AutoCAD to easy-to-understand basic concepts Teaches only what is essential to operating AutoCAD first, thereby immediately building student confidence All basic commands are documented step-by-step, meaning that what the student needs to type in and how AutoCAD responds is all spelled out in discrete and clear steps with screen shots added as needed Using the author’s extensive multi-industry knowledge of what is important and widely used in practice versus what is not, the material is presented by immediately immersing the student in practical, critically essential knowledge, with no padding of text or filler material All concepts are explained first in theory, and only then is AutoCAD introduced and the actual "button pushing" discussed. This is one of the key concepts in having students understand exactly what it is they are doing and why, before they do it
