ENGINEERING COMMUNCATIONS2/2

• 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

• 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
