Engineering graphics is the process of defining an object graphically before it is constructed and used by consumers. Previously, this process for producing a drawing involved the use of drawing aids such as pencils, ink pens, triangles, T-squares, and so forth to place an idea on paper before making changes and producing blue-line prints for distribution. The basic principles and concepts of producing engineering drawings have not changed, even when the computer is used as a tool.
This text uses the basics of engineering graphics to produce 2D drawings and 3D computer models using AutoCAD and a series of tutorial exercises that follow each chapter. Following the tutorials in most chapters, problems are provided to enhance your skills in producing engineering drawings. A brief description of each chapter follows:
Chapter 1. Getting Started With Autocad
This first chapter introduces you to the following fundamental AutoCAD concepts: Screen elements and workspaces; use of function keys; opening an existing drawing file; using Dynamic Input for feedback when accessing AutoCAD commands; basic drawing techniques using the LINE, CIRCLE, and PLINE commands; understanding absolute, relative, and polar coordinates; using the Direct Distance mode for drawing lines; using all Object snap modes, and polar and object tracking techniques; using the ERASE command; and saving a drawing. Drawing tutorials follow at the end of this chapter.
Chapter 2. Drawing Setup And Organization
This chapter introduces the concept of drawing in real-world units through the setting of drawing units and limits. The importance of organizing a drawing through layers is also discussed through the use of the Layer Properties Manager palette. Color, linetype, and lineweight are assigned to layers and applied to drawing objects. Advanced Layer tools such as isolating, filtering, and states and how to create template files are also discussed in this chapter.
Chapter 3. Autocad Display And Basic Selection Operations
This chapter discusses the ability to magnify a drawing using numerous options of the ZOOM command. The PAN command is also discussed as a means of staying in a zoomed view and moving the display to a new location. Productive uses of real-time zooms and pans along with the effects awheel mouse has on ZOOM and PAN are included. Object selection tools are discussed, such as Implied Windowing, Noun/Verb Selection, Selection Cycling, and the Quick Select command, to name a few. Finally, this chapter discusses the ability to save the image of your display and retrieve the saved image later through the View Manager dialog box.
Chapter 4. Modifying Your Drawings
This chapter is organized into two parts. The first part covers basic modification commands and includes the following: MOVE, COPY, SCALE, ROTATE, OFFSET, FILLET, CHAMFER, TRIM, EXTEND, and BREAK. The second part covers advanced methods of modifying drawings and includes ARRAY , MIRROR, STRETCH, PEDIT, EXPLODE, LENGTHEN, JOIN, UNDO,and REDO. Tutorial exercises follow at the end of this chapter as a means of reinforcing these important tools used in AutoCAD.
Chapter 5. Performing Geometric Constructions
This chapter discusses how AutoCAD commands are used for constructing geometric shapes. The following drawing-related commands are included in this chapter: ARC, DONUT, ELLIPSE, POINT, POLYGON, RAY, RECTANG, SPLINE, and XLINE. Tutorial exercises are provided at the end of this chapter.
