Technical drawing book download

The textbook is organized in three comprehensive parts. Part II Projection Techniques contains various projection techniques used in engineering for technical drawings.

These techniques have been explained with a number of line diagrams to make them simple to the students. The accompanying CD contains the animations using creative multimedia and PowerPoint presentations for all chapters.

In a nutshell, this textbook will help students maintain their cutting edge in the professional job market. Includes chapters on aspects of technical drawing and AutoCAD as a tool. Treats problems in the third angle as well as first angle methods of projection in line with the revised code of Indian Standard Code of Practice for General Drawing.

The three books may be used together or separately to suit a variety of needs. It provides excellent technical detail and motivating real-world examples, illuminating theory with a colorful, highly-visual format complemented with concise text. Designed for busy, visually-oriented learners, this guide expands on well-tested material, fully updated for the latest ASME standards, materials, industries and production processes.

Its up-to-date examples range from mechanical, plastic, and sheet metal drawings to modern techniques for civil engineering, architecture, and rapid prototyping. Throughout, clear, easy, step-by-step descriptions teach essential sketching and visualization techniques, including the use of 3D and 2D CAD. All color visuals are tightly integrated with text to promote rapid mastery. 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 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 provides a solid foundation for students going on to learn advanced CAD concepts and techniques paper space, viewports, xrefs, annotative scaling, etc. In recognition of the diverse career interests of our students, Technical Drawing 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.

Eventually, CAD provided the designer with the ability to perform engineering calculations. During this transition, calculations were still performed either by hand or by those individuals who could run computer programs. CAD was a revolutionary change in the engineering industry, where draftsmen, designers and engineering roles begin to merge. It did not eliminate departments, as much as it merged departments and empowered draftsman, designers and engineers.

CAD is an example of the pervasive effect computers were beginning to have on industry. Current computer-aided design software packages range from 2D vector-based drafting systems to 3D solid and surface modelers. Modern CAD packages can also frequently allow rotations in three dimensions, allowing viewing of a designed object from any desired angle, even from the inside looking out.

Some CAD software is capable of dynamic mathematical modeling. CAD technology is used in the design of tools and machinery and in the drafting and design of all types of buildings, from small residential types houses to the largest commercial and industrial structures hospitals and factories. CAD is mainly used for detailed engineering of 3D models or 2D drawings of physical components, but it is also used throughout the engineering process from conceptual design and layout of products, through strength and dynamic analysis of assemblies to definition of manufacturing methods of components.

It can also be used to design objects such as jewelry, furniture, appliances, etc. Furthermore, many CAD applications now offer advanced rendering and animation capabilities so engineers can better visualize their product designs. CAD has become an especially important technology within the scope of computer-aided technologies, with benefits such as lower product development costs and a greatly shortened design cycle.

CAD enables designers to layout and develop work on screen, print it out and save it for future editing, saving time on their drawings. Computer-aided design is one of the many tools used by engineers and designers and is used in many ways depending on the profession of the user and the type of software in question. CAD is one part of the whole digital product development DPD activity within the product lifecycle management PLM processes, and as such is used together with other tools, which are either integrated modules or stand-alone products, such as:.

CAD is also used for the accurate creation of photo simulations that are often required in the preparation of environmental impact reports, in which computer-aided designs of intended buildings are superimposed into photographs of existing environments to represent what that locale will be like, where the proposed facilities are allowed to be built.

Potential blockage of view corridors and shadow studies are also frequently analyzed through the use of CAD. CAD has been proven to be useful to engineers as well. Using four properties which are history, features, parametrization, and high-level constraints.

The construction history can be used to look back into the model's personal features and work on the single area rather than the whole model. Parameters and constraints can be used to determine the size, shape, and other properties of the different modeling elements.

The features in the CAD system can be used for the variety of tools for measurement such as tensile strength, yield strength, electrical or electromagnetic properties.
