Catalog Description: Multiview, graphs, isometric and oblique projection; sectional views and dimensioning; concepts of descriptive geometry.

I. OBJECTIVES:

  1. To provide the student with a comprehensive knowledge of the fundamentals, principles, and techniques used in engineering graphics.

  2. To provide an accepted universal mode of technical communication, a mode for self expression and a mode for spatial problem solution and analysis with the aid of graphical procedures.

  3. To develop within each student an ability to mentally visualize and conceive spatial delineation of technical problems.

  4. To develop a logical and sequential attack process in analysis and solution to technical problems.

  5. To provide a firm, basic foundation on which the student may build advance courses.

  6. To familiarize the student with computer—aided design/drafting.

III. GENERAL CONSIDERATIONS:

There will be opportunity for lab work outside regularly scheduled classes. Please refrain from asking other instructors to provide a place for you in their classes. Open lab is from 8 to 5 Monday through Friday except when a class is in session. The classroom schedule is posted at the entrance. Please check schedule before entering.

Students who miss class are not permitted to make-up tests unless an excused absence is received from the Dean of Students, Student Personnel Services. Workbook assignments are not accepted past the due date established except for emergency accident or serious illness reasons. Strict punctuality and efficient use of class time is expected. Five points are deducted from the total accumulated lab points for each unexcused absence.

STUDENTS ARE NOT ALLOWED TO LEAVE CLASS UNTIL DISMISSED.

Unless otherwise notified, all problem assignments will be due on Friday of each week by five o'clock p.m. No late drawing assignments are accepted. Staple worksheets together in order from lowest sheet number to highest. Handouts are placed last.

IV. PERSONAL STORAGE FACILITIES

Hall lockers are available on a first come first serve basis. You claim a locker by attaching your personal padlock. You must share a locker with another person. Use the lockers for storing coats, backpacks, other personal belongings.

V. TEXT AND REFERENCE BOOKS

Secure a copy of the textbook and workbook promptly. The student will be expected to study and become familiar with the material assigned before the lectures and demonstration and before the process or procedure is attempted through assigned lab worksheets.

TEXTBOOK: Earle, J. H. Engineering Design Graphics, 8th edition. Reading, Massachusetts: Addison Wesley, 1987.

WORKBOOK: Earle, J. H. Graphics and Geometry 1. College Station, Texas: CreativePublishing Company, 1986.

VI. DRAFTING INSTRUMENTS AND SUPPLIES

Purchases of equipment and materials will be made from sources outside the classroom except for print and sketch paper. Students will be provided print paper at a charge to cover cost.

The following equipment and materials are needed for this course. They may be purchased at the University Book Store or at most office supply stores.

  1. Ames lettering guide
  2. Erasing shield
  3. Ruby red eraser
  4. Drafting or masking tape
  5. Compass
  6. Dividers
  7. Two scales: Engineers Scale and Architects scale
  8. Pencil(s) mechanical or thin line
  9. Two grades of pencil leads
      H grade
      4H grade
  10. Pencil pointer
  11. Problem book
  12. Print Paper (provided by instructor)
  13. Cross-section paper (provided by instructor)

VII. BLUEPRINT ROOM

Use of the blueprint room is limited to students enrolled in drafting classes. This room is open to students by instructor permission only. Drafting students can use the reproduction equipment in this room only after a demonstration and permission by the instructor to complete scheduled assignments.

VIII. EVALUATION SYSTEM

Evaluation will come from three primary areas. These areas and their contribution towards the final grade in the course is as follows:

    I. Fourteen problem assignments to be completed in the laboratory The first assignment is a written report. 40%

    II. Five tests at approximately two week intervals 40%

    III. Final examination 20%

The letter grade is derived from a percentage as follows:
    90 - 100% = A
    80 - 89% = B
    70 - 79% = C
    60 - 69% = D
    0 - 59% = F
*NOTE: Five points are deducted from the total accumulated lab points for each unexcused absence.

IX. STUDENTS WITH DISABILITIES

If you have a documented disability and wish to discuss academic accommodations, please contact the coordinator of the Office of Disability (581-6583) as soon as possible.
