3. GRAPHICAL COMMUNICATION
• The engineer must be able to create graphical
representations to describe his work
• The engineer must be able to read graphical
representations produced by others
• The intent of the graphical representation
may be to show the general design to a client
( no details )
• Or it may show details ( dimensions,
tolerances, specifications, ….)
4. Types of Graphical Representations
• Sketching :
- is the art of communicating graphical ideas
without using traditional mechanical tools
(hand drawing)
- It is used to show preliminary ideas
- Sometimes are computer drawn, but many
times are hand drawn
5. • Pictorial Representations (3D)
Perspective representations ( one- point , or
two- point perspectives )
- The most realistic to the human eye.
- Useful for describing information to non
engineers
Isometric Representations (30-degree with
the horizontal direction and vertical lines)
6. • 2D Graphical Representations:
- Orthographic Representations ( front, top or
plan, and side views)
- Section Views
- Auxiliary Views

18. THE ENGINEER AS A SPEAKER
• Engineers make many presentations to managers
at department meetings, executives, clients, and
at professional meetings
• In all these presentations, the engineer is the
speaker, and must present his work in a
professional, friendly, clear, brief, complete and
attractive style
• Like public speakers, engineers must prepare their
material carefully, and rehearse their presentations
well to be effective
19. • Speak clearly and distinctly
• Speak sincerely, without hesitation, and with
reasonable deliberation
• Answer questions and explain details in a
pleasant style that would keep the audience
attentive and interested
• Becoming a good speaker is a skill that
requires considerable training & effort
