Engineering Graphics, AutoCAD and Programming, CE20

1
Engineering Graphics, AutoCAD and Programming,
CE20

• Kurt McMullin, Ph.D., P.E.
• San Jose State University

2
Course Goals from CE Faculty

• To introduce the students to engineering
  graphics, both computer and manual.
• To learn basic skills in AutoCAD to be used in
  upper-division CE classes.

• To gain additional skills in computer programming
  through the use of Visual Basic for EXCEL.
• To be introduced to the types of projects that
  civil engineers design and build.

3
Who we are not?

• Not artists. Their work transfers emotions.
• Not architects. We will not work with shading,
  perspectives, or texturing.

4
Who we might be

• Drafters. Most times we produce work for
  drafters to perform.
• We may be called upon to draw production quality
  drawings when the drafting people are overloaded.

5
Who we will probably be

• Civil Engineers.
• Most of our time will be involved in the design
  and the calculation of engineering projects.
• Usually we will produce small working drawings of
  our result.

• As part of the calculations, we often will use
  spreadsheets (such as EXCEL) that we might
  create, or that another engineer may have made
  before.

6
Teaching Style

• A recent study listed the methods of classroom
  instruction that Civil Engineering students
  prefer.
• The list shows the favorites

• Lecture/Discussion/ Problem Solving.
• Working in teams, group interaction.
• Visual presentations by instructor (Mmedia,
  video)
• Computer assignments.

7
And the Losers!

• And it also listed those least preferred.

• Homework, especially ungraded.
• Formal chalkboard lecture.

8
Our Course

• Project-based learning students learn the
  material to meet the course objectives by
  completing a project that requires use of the
  skills learned.
• Cooperative learning students work in small
  teams, sharing their knowledge and learning from
  their fellow team members.

9
Drafting Engineer A

• Someone who can produce a wide variety of
  drawings with minimal guidance.
• Exams and projects show that engineer can analyze
  information and make rational decisions.

10
Drafter B

• Can produce drawings on a wide variety of
  projects but needs assistance in understanding
  the layout, orientation, and/or other pertinent
  information.
• Can choose the appropriate drawing view for a
  project.
• Can scale and layout drawing.

11
Tracer C

• Can reproduce the changes marked by another
  engineer.
• Is unable to evaluate the project and make
  decisions about views, scale and/or layout.

12
Beginner D

• Can use some commands of AutoCAD but is unable to
  complete the drawings assigned.
• Shows potential but needs to improve in
  productivity.

13
Unemployed F

• Is not able to contribute to completion of
  project.
• Is more of a liability than asset.

14
Professionalism

• Does not require close supervision.
• Regards their supervisor as their peer, and vice
  versa.
• Takes full responsibility for their actions.
• Avoids rumors.

• Continual self-improvement.
• Loyal to fellow workers and employers.
• Does not advance at the expense of others.
• Proud of profession.

15
Extra Credit for CE20

• I will allow up to 5 of the course grade for
  students to receive extra credit.
• This extra credit is awarded for extracurricular
  activities where the student participates.
• Credit is received after a paper explaining the
  work is written and reviewed.

16
Rules for Extra Credit

• Activity must be related to civil engineering.
• Student must play an active role in the activity.
  Officer of a club, attendance at seminars and/or
  presentations.
• Student is not compensated credit for CE105,
  class field trips, paid internships.

17
Acceptable Ideas?

• A wide variety of activities and/or ideas will
  qualify for this extra credit.
• Please talk to the instructor about what you are
  involved with, how it could be used for extra
  credit, and how much extra credit the activity is
  worth.

McMullins Law of Plotters

• Theorem 1
• Plotters and printers work 99 of the time.

19
Corollary 1

• 1 of the time, printers and plotters dont work.
• This always occurs before deadlines.

20
Corollary 2

• Your clients schedule is NOT dependent upon the
  operation of your computer, printer or plotter.

21
Therefore

• We must learn to schedule our work so that an
  inoperable computer, printer, or plotter will not
  cause a crisis.
• Keep hardcopies of works-in-progress. Remember
  that you may need to substitute the draft for the
  final document.
• Know of additional facilities for emergency.
  Campus computer labs, Kinkos, CAD Services.

22
Civil Engineers sometimes work in less than ideal
situations

• Civil Engineers often work in situations without
  support equipment.
• Sometimes even with no power and no electricity.
• Earthquake response, accident investigation.

• We cannot become so dependent upon computer
  facilities that when we lose them we cant
  continue our work.
• Lives sometime depend upon our immediate response
  to all types of disasters.
