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

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, ….)

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

• 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)

• 2D Graphical Representations:- Orthographic Representations ( front, top or
plan, and side views)- Section Views- Auxiliary Views

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
![Page 19: GENN 001 Lec 10](https://reader035.vdocuments.site/reader035/viewer/2022062319/5564ec64d8b42afb268b502c/html5/thumbnails/19.jpg)
• 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
