The newly revised 9th edition of Basic Blueprint Reading and Sketching continues the traditions in helping to readers achieve competence in reading and sketching technical drawings. This classic interactive book/workbook will help users develop skills in reading and interpreting industrial drawings and preparing basic to advanced technical sketches. This book will provide them with basic principles, concepts, ANSI and SI Metric drafting symbols and standards, terminology, manufacturing process notes, and other related technical information contained on a mechanical or CAD drawing. Each unit features a basic principle and at least one blueprint and assignment that encourages students to practice newly learned skills. This edition contains coverage of the latest ANSI, ISO, AWS and ASME standards.

Summary

Chapter 1: Introduction to Blueprints

* Defines blueprints and their purpose in construction
* Describes the types of blueprints (architectural, structural, mechanical, electrical)
* Provides an overview of the components of a blueprint, including title block, legend, scales, and symbols

Real Example: A blueprint for a residential home shows the floor plan, elevations, and sections, providing all the necessary information for construction.

Chapter 2: Lines and Symbols

* Covers the different types of lines used in blueprints (object, dimension, center, phantom, etc.)
* Explains the standard symbols used to represent objects on blueprints, such as doors, windows, plumbing fixtures, and electrical components

Real Example: A toilet is represented by a rectangle with a curved top and two smaller rectangles inside for the tank and bowl.

Chapter 3: Scales

* Discusses the importance of scales in blueprints
* Explains how to determine the actual size of objects by using the scale provided
* Covers the different types of scales (full, reduced, enlarged)

Real Example: A blueprint with a scale of 1/4" = 1'-0" means that 1/4 inch on the blueprint represents 1 foot in real life.

Chapter 4: Dimensions and Annotations

* Describes the methods used to dimension objects on blueprints (linear, angular, radius)
* Explains the purpose of annotations on blueprints, such as notes, labels, and specifications

Real Example: A dimension of 8'-0" between two walls indicates that the actual distance between the walls is 8 feet. An annotation might specify that a particular wall be constructed of brick.

Chapter 5: Basic Sketching Techniques

* Teaches the basics of sketching, including line weight, proportion, and perspective
* Provides tips for sketching common objects and symbols used in blueprints

Real Example: A sketch of a door can be made by drawing a rectangle and adding a knob and a hinge.

Chapter 6: Orthographic Projection

* Explains the principles of orthographic projection
* Covers the different views (top, front, side, isometric) used to represent objects in blueprints

Real Example: A blueprint for a cabinet might have a top view, front view, and side view, each showing a different perspective of the object.

Chapter 7: Sections and Elevations

* Describes the purpose and use of sections and elevations
* Explains how to read and interpret sections and elevations on blueprints

Real Example: A section through a wall shows the interior construction, while an elevation shows the exterior appearance from a particular direction.
