1. Drafting Boot Camp

2. Why Study Drafting?  Drafting is a form of graphic communication  “A picture is worth a thousand words.”

3. Drafting as a Language  Drafting is called a “universal language” Symbols (lines and figures) have specific meaning are used The symbols accurately describe the shape, size, material, finish, and fabrication or assembly of a product

4. Drafting Plans

5. Drafting as a Language  Drafting is also the “language of industry”  Industry uses this precise language because the drawings must communicate the information the designer had in mind to those who produce the product.

6. CAD  Computer Aided Design

7. CAD Plotters  When a design is complete, high-speed plotters or printers turn out hard (paper) copies showing the part or design.

8. Fields of Drafting  Aerospace  Architectural  Automotive  Electrical  Electronic  Printed circuitry design  Topographical  ETC… Yes! IT IS EVERYWHERE!!

12. T-square  Used for horizontal lines & as a guide for other instruments

13. Triangles  Tool for drawing vertical & inclined lines  45° Triangle  30°-60° Triangle

14. Protractor  Used for drawing inclined lines & angles

15. Compass  Tool for drawing circles & arcs

16. French Curve  Also called an Irregular curve  Consists of a variety of curves that can be used when arcs are not satisfactory

17. Divider  Looks like a compass, but both legs have steel pints at the end  Tool used for measurement purposes

18. Templates  Used to help in drawing shapes & symbols  Templates for producing squares, ellipses triangles, etc.

19. Orthographic or Multiview Drawings  Imagine that you have an object suspended by transparent threads inside a glass box, as in figure 3. Figure 3 - The block suspended in a glass box

20. Orthographic or Multiview Drawings, Continued…  Then draw the object on each of three faces as seen from that direction. Unfold the box (figure 4) and you have the three views. We call this an "orthographic" or "multiview" drawing. Figure 4 - The creation of an orthographic multiview drawing

21. Orthographic or Multiview Drawings, Continued…  Figure 5 shows how the three views appear on a piece of paper after unfolding the box. Figure 5 - A multiview drawing and its explanation

22. Orthographic or Multiview Drawings, Continued…  Which views should one choose for a multiview drawing?  The views that reveal every detail about the object. Three views are not always necessary; we need only as many views as are required to describe the object fully.

23. Orthographic or Multiview Drawings, Continued…  For example, some objects need only two views, while others need four. The circular object in figure 6 requires only two views. Figure 6 - An object needing only two orthogonal views
