This document discusses engineering communications, including written, graphical, and oral communications. It focuses on graphical communications, describing types of graphical representations like sketching, pictorial representations, and orthographic representations. It notes that engineers must be able to create and read graphical representations to describe their work. The document also briefly discusses the importance of oral communications and how engineers must prepare and deliver presentations professionally.

ENGINEERING
ENGINEERING COMMUNCATIONS
2/2

2. • Written engineering communications (Lec 9)
Memos, letters, e-mails, reports, journal
papers, specifications
• Graphical communications
Sketching, 3D pictorial representations, 2D
orthographic representations
• Oral communications

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
