Engineering Communication
 Communicate - to send information so
  that it is satisfactorily received or
  understood.
 Here is a recording from a training tape
  on how guided missiles locate themselves
  and get to the target. Listen to see if this
  information is communicated as well as it
  could be.
Engineering Communication
 Engineers need to be able to
  communicate thoughts, ideas, and plans
  to many other specialists in many
  different fields.
 Engineers work in teams with people from
  different backgrounds.
 Therefore, it is necessary to have a variety
  of communication skills. (VCSU, 2006)
     Communication Skills
 Interpersonal -
    Do you picture the engineer as the
     nerd in the corner with the pocket
     protector?
    Those days have passed.
    Engineering today means teamwork.
    The Thomas Edison mythology would
     not work on problems like the
     Manhattan Project. (VCSU, 2006)
      Communication Skills
 Written
   It may seem that engineering projects
    would be too technical to have much
    use for composition skills.
   However, in a survey of over 4000
    practicing engineers, 99% listed
    composition courses as important for
    future engineers. (VCSU, 2006)
    Communication Skills
 Why?
   Engineers write proposals. They need to
    convince people to spend money on their
    projects.
   These “shopping lists” may be read by their
    immediate boss, the president of the
    company, a US Senator, the DOD
    (Department of Defense), etc.
   Engineers also write reports when a design
    change is needed or to explain a failure.
    (VCSU, 2006)
      Communication Skills
 Oral and Electronic Presentation -
   For the same reasons as listed for
    written skills, oral and electronic
    presentation skills are needed.
   The use of presentation software and
    hardware can vastly improve the
    effectiveness of an engineer’s report.
   This is especially important with regard
    to concurrent engineering. (VCSU, 2006)
   Concurrent Engineering
 Concurrent means occurring at the same
  time.
 Concurrent engineering is the process in
  which all aspects of the design process
  happen at the same time.
 Effective communication is critical.
 All aspects of design, manufacturing and
  support have to be coordinated. (VCSU, 2006)
  Concurrent Engineering
 Development teams are used to
 complete projects. The team effort:
   Reduces development time
   Produces a faster time to market which
    equals increased market share
   Increases quality
   Increases productivity
   Eliminates costly and timely re-designs
   Lowers implementation risks
      (Berkeley, 1997)
      (VCSU, 2006)
  Mathematical Expression
 Recall from Unit 1 the math
  requirements for an engineering
  major.
 Math is an important tool that
  engineers use to determine design
  solutions.
 Math is also a method to express
  design solutions. (VCSU, 2006)
  Mathematical Expression
 A mathematical expression can be
  written in the form of a statement that
  can be translated into a formula and
  then tested.
 A simple example:
   d = distance, v = velocity, t = time
   v=d/t
   A train travels 50 miles in 30 minutes. What is
    the velocity of the train? (VCSU, 2006)
  Mathematical Expression
 “A picture is worth a thousand words”
 Which is easier to interpret? The following
  table or graph?

                                                    Time
  Mathematical Expression
 The information is the same in both the
  table and the chart.
 The chart clearly shows that during 10:00
  and 2:00 the measurements increase.
 This is a replica of a situation in which the
  machine operator was leaning against his
  CNC machine during coffee break
  throwing his machining out of tolerance.
 The change in measurements were not
  associated with the change in time until it
  was put into chart format.
  Mathematical Expression
 As an engineer, it is critical to use
 the best expression of mathematics
 to clearly communicate with others.
2-Dimensional Drafting & Sketching
 Formerly referred to as drafting or
  engineering drafting (VCSU, 2006)
 (OCIW, 2003)
2-Dimensional Drafting & Sketching

 This form of communication has been an area of skill
  to engineers and architects for hundreds of years.
  (VCSU, 2006)
2-Dimensional Drafting & Sketching

 A drafting course would teach
 students to:
   Print clearly and uniformly
   Create accurate and uniform
    dimensions
   Make object lines of uniform thickness
    to make center lines, dimension lines,
    hidden lines, etc. distinguishable. (VCSU,
   2006)
2-Dimensional Drafting & Sketching

 The next objective was to represent
  objects with top, front, and side
  views.
 This is called orthographic
  projection. (VCSU, 2006)
2-Dimensional Drafting & Sketching

 The next step was to teach isometric
 projection.
          Perspective Drawing
 1 point perspective




 2 point perspective




 3 point perspective
   (Anime-by-Example,1998).
         2 Point Perspective




 (Anime-by-Example,1998).
         3 Point Perspective




 (Anime-by-Example,1998).
2-Dimensional Drafting & Sketching

 The idea behind teaching these skills (that
  is still valid today) is that many great
  inventions and products are first put down
  on paper on a napkin or the back of an
  envelope.
 Engineers are required to keep dated
  logbooks, including sketches to
  document who created an invention first.
 The award of patents are often
  dependant on these logs. (VCSU, 2006).
2-Dimensional Drafting & Sketching
 Even in 1987, engineering students at
  NDSU had to take a minimum of 2
  quarters of engineering drafting
  producing drawings like the ones just
  shown with front, top, side and isometric
  views.
 The drafting course was one of the most
  challenging and often seen as a test of
  engineering determination - referred to as
  the “weed out” class. (VCSU, 2006).
   3 Dimensional Modeling
 Today (2006) the class offered at NDSU is:
  Fundamentals of Visual Communications
  for Engineers A visual communications for
  design and manufacturing, computer-
  aided drawing and design, three-
  dimensional modeling and orthographic
  projections, geometric dimensioning and
  tolerancing… (NDSU, n.d.)
   3 Dimensional Modeling
 3-D modeling software is more productive
  at communicating a design concept.
 Technology has drastically changed the
  way we can communicate design ideas.
 Not everyone that engineers are selling
  their idea to can read a mechanical
  drawing. (VCSU, 2006).
   3 Dimensional Modeling
       Characteristics
 Modeling provides a means of visually
  and virtually representing ideas.
 The term computer model describes a
  computer-generated perspective
  drawing. They are not physical models,
  but their realism allows them to play
  similar roles. (VCSU, 2006).
   3 Dimensional Modeling
       Characteristics
 Model building is a skill and process
 to translate designs into a visual form
 to be used for discussion, analysis,
 development, and testing. (VCSU, 2006).
   3 Dimensional Modeling
       Characteristics
 By creating a model on the computer,
  companies can save a great amount of
  time and money in development and
  redesign phases.
 The model can be designed, modeled,
  and tested on the computer before the
  first one is manufactured. This speeds up
  production. (VCSU, 2006).
   3 Dimensional Modeling
       Characteristics
 After a model is created virtually, an
  actual physical model can be made
  through a computer controlled process
  called stereolithography.
 This uses lasers to “trace” out a part from
  a liquid polymer. Where the lasers
  intersect, the polymer hardens and forms
  the solid part of the model.
 Another process that sprays on layers of
  polymer is called Rapid Deposition
  Modeling (RDM). (VCSU, 2006).
         Activity Sample
 Hand out Unit 3 Activity
 For your assignment, you will be in
  teams of two.
 Put together a power point
  presentation that you will give to the
  class per the handout provided.
 A sample of what you will put
  together is as follows:
        Activity Sample
      1 point perspective
 Perspective is the geometrical
 technique in drawing that creates
 the illusion of three-dimensional
 space on a two-dimensional plane
 (your paper). It is a technique that
 uses overlapping, objects receding
 in space, horizon lines and vanishing
 points to create a feeling of depth.
        Activity Sample
      1 point perspective
 There is 1 point perspective, 2 point,
  3 point, multi point, and no point.
 1 point perspective has all lines
  converging on one vanishing point.
        Activity Sample
      1 point perspective
 The following is an example of an
 artists drawing from one point
 perspective that gives the feeling of
 looking into another room. It was
 painted by Santa Maria Novella
 circa 1428 and titled Trinity.
