Introduction

• CAD (Computer Aided Design)
• Develop designs and drawings and plot them on
  paper or film
• 3D display

4
AutoCAD Toolbox

• Drawings and models are constructed usign XYZ
  coordinates (Cartesian or rectangular coordinate
  system)
• Angles measured in a counter clockwise direction
• Text annotation and dimensions
• Objects can be given colors, patterns, and
  textures
• Tools to create isometrics, 3D and surface models

5
Applications of AutoCAD

• Construct, layout, dimension, and annotate 2D
  drawings
• Colors and layers convey information
• 2D, 3D, or exploded assemblies
• Wireframe, surface, rendered
• Animation and virtual reality

6
AutoCAD Drawing Method

• Learn the XYZ coordinate system
• Plan your work and organize your thoughts
• Learn and use classroom or office standards
• Save your work often

7
Planning Checklist

• Analyze the problem
• Study all engineering sketches
• Locate and list all available resources
• Determine standards applicable to project
• Sketch the problem
• Decide on the number and kinds of views desired
• Determine the final plotted scale of the drawing
  and of all views
• Determine drawing sequence
• List the AutoCAD commands to be used
• Follow the standard and refer to the resources as
  you work
• See Working procedures checklist

Exercise 1

• Using a piece of paper and a pen or pencil, make
  a sketch similar to Figure 1-4. Label the origin,
  X axis, and Y axis. Sketch a dot located at the
  intersection of three units in the X axis and
  three units in the Y axis.

Exercise 2

• Open the Properties window by pressing the
  Ctrl1 key combination.
• Dock the Properties window to the right of the
  screen.
• Open DesignCenter by pressing the Ctrl2 key
  combination.
• Make the Properties window and DesignCenter
  floating. Move them around on the screen.
• Use the Ctrl key to position the Properties
  window and DesignCenter to the left of the screen
  without docking them.
• Close DesignCenter.
• Set the Properties window to auto-hide.

15
Selecting AutoCAD Commands

Using Help

• Exercise
• Use help to find how to change units and limits
• Use help to draw (via the menu, command, and
  toolbar)
• 4 Lines
• 5 Polygons
• 3 Large Squares
• 2 Rectangles
• Enclose them all in a Revision Cloud
• Set the color of each object to red, green, or
  blue
• Save file as classwork1.dwg and Exit.
• Get into groups of two and use these basic
  shapes, draw one of the following
• House
• Car
• Your Cell phone
• A Clock
• Save this file as classwork2.dwg
