Architectural Drafting and Design  (ISBN-10: 1401867154 | ISBN-13: 9781401867157)

Written to meet the most recent editions of IRC and IBC, this exceptional, full-color fifth edition is designed for beginning, intermediate, and advanced architectural drafters and CAD operators alike. Architectural Drafting and Design, 5E features the basics of residential design through the various types of projects that a designer or architect would likely complete during the actual design process. Coverage begins with an introduction to architectural styles that have dominated the field over the last four centuries, followed by basic design components related to the site and structure. A hallmark of this best-seller is its step-by-step instructions for the design and layout of each type of drawing associated with a complete set of architectural plans, with projects that can be completed using either CAD or manual drawing methods. Readers will come away with the knowledge needed to complete each of the drawings required by most municipalities to obtain a building permit for a single-family residence. Comprehensive coverage also explores the field of commercial drafting, as well as basic materials used for construction, common construction methods, and drawings typically associated with commercial construction.

Civil Drafting for the Engineering Technician  (ISBN-10: 1418009520 | ISBN-13: 9781418009526)

A real life civil design project for site development is recreated through each chapter in this book to prepare readers for what to expect when working in the field. Coverage begins by introducing the basic setups and standards that anyone beginning a civil design CAD project should know, then moves on to the fundamental concepts common to most civil engineering projects such as grading, contours, and surveying. Readers will then explore the process of creating different types of drawings typically necessary for civil design and see how changing parts of a design can affect the entire project process. The book concludes with methods for estimating quantities for the different types of materials and work that will likely be encountered in an actual drafting assignment.

Engineering Drawing and Design  (ISBN-10: 1418029874 | ISBN-13: 9781418029876)

For more than twenty years, customers have relied on Engineering Drawing and Design for its easy-to-read, A-to-Z coverage of drafting and design instruction that complies with industry standards. The fourth edition continues its tradition of excellence with a multitude of actual quality industry drawings demonstrating content coverage, and the addition of new problems to the hundreds already on-hand for real world, practical application. The engineering design process featured in this revision contains all-new material following an actual product design from concept through manufacturing, and a multitude of new design problems for challenging applications or for use as team projects. Other enhancements include updated coverage of Civil Drafting, 3D CADD, solid modeling, parametric applications, and more.

He was an active member of the Canadian Standards Association (CSA) Committee on Technical Drawings. Mr. Jensen has represented Canada at international (ISO) conferences on engineering drawing standards, which took place in Oslo, Norway and Paris, France. He also represented Canada on the ANSI Y14.5M Committee on Dimensioning and Tolerancing. He is the successful author of numerous texts including Engineering Drawing and Design, Fundamentals of Engineering Drawing, Geometric Dimensioning and Tolerancing for Engineering and Manufacturing Technology, Computer-Aided Engineering Drawing, and Home Planning and Design. Before he began teaching, Mr. Jensen spent several years in industrial design. He also supervised the evening courses in Oshawa and was responsible for teaching selected courses for General Motors Corporation apprentices.
