COURSE DESCRIPTION: Introduction to the principles of drafting to include terminology and fundamentals, including sizes and shape
descriptions, projection methods, geometric construction, sections, auxiliary views, and reproduction process.
TEXTBOOKS:
“Technical Drawing” by Frederick E. Giesecke, 13rd Edition, published by Prentice Hall, Perason
Education Inc. [required]
REQUIRED COURSE MATERIALS: See attached Drawing Equipment List
LEARNING OUTCOMES: Demonstrate an understanding of geometric construction, various view selections, and principles of working
drawings, competency in drafting principles in plane geometry, technical sketching, orthographic projection theory and practice, auxiliary
views, and competency in sectioning, dimensioning, and tolerance.
SCANS SKILLS: The Department of Labor has identified skill sets that U.S. employers want most in entry level employees. It is our
commitment to prepare every student with the knowledge and skills needed to succeed in today’s dynamic environment. Toward this end,
the following skills will be included in this course

Listening: receives, attends to, interprets, and responds to verbal messages and other cues such as body language in ways
that are appropriate to the purpose; for example, to comprehend; to learn; to critically evaluate; to appreciate; or to support
the speaker.

Seeing with Minds Eye: Organizes and processes symbols, pictures, graphs, objects or other information.

Time management: Selects relevant, goal-related activities, ranks them in order of importance, allocates time to activities
and understands, prepares and follows schedules.
The student will be given a verbal description of a 3D geometric object that is to be drawn, The description will applicable
dimensions and required annotation. It will prepare and follow a schedule to develop a three view orthographic projection of the object
based on their visualization of the object from its description and their evaluation of the supplemental data provided them.
Evaluation of these skills will be assessed by the timely completion, completeness and accuracy of the finished assignment. The
assignment will carry the same numerical value as any other assignment.
COURSE CONTENTS
 Understanding the drafter's role in industry
 Using the various manual drafting instruments to produce technical drawings
 Producing free-hand sketches
 Identifying the various lines used on an engineering drawing
 Demonstrating good free-hand lettering
 Defining common geometric shapes
 Creating views of an object using orthographic projection
 Drawing isometric, oblique and perspective views of objects

Note: Refer to the "Course Outline & Assignment" document for scheduled weekly activities - Refer to the "Drafting Equipment
& Supplies" list for drafting equipment requirements.) The student should bring the textbook and drafting instruments to class
every day, unless otherwise instructed.
COURSE EVALUATION PROCEDURE: The student will be evaluated and receive a final grade based upon the following
criteria:
 Laboratory work consisting of assigned technical drawing problems.
 A minimum of 2 tests: (a mid-term and a final examination): NOTE: - Individual instructors may schedule more tests if
desired
 Class and laboratory attendance, active participation in class, professional attitude and growth in terms of
technical skill development and teamwork within the laboratory environment shall be taken into consideration.
GRADING PROCEDURE:
A = 90 –100
B = 80 – 89
C = 70 – 79
D = 60 – 69
F = below 59
The drawing portion of the above evaluation criteria shall be based on the layout, dimensional accuracy, neatness, and timely
completion.
LATE ASSIGNMENT POLICY: Students are encouraged to turn assignments in on time if at all possible. This allows the
instructor to grade the work, return it to the student and the student use the feedback as a learning tool.
MAKE-UP TEST/PROJECT POLICY: The student must request a make-up test and it should be scheduled at the earliest
possible date following the quiz (or mid-term) missed. NO make-up test is given for the final examination.
EXTRA CREDIT: Extra credit work is offered only to assist students that that have a grade range of “D” or “F” at the mid-term
break. This work cannot be substituted for regular assignments and can only raise the final grade to a maximum of a “C”.
STUDENTS WITH DISABILITIES
Any student with a documented disability (e.g. physical, learning, psychiatric, vision, hearing, etc) who needs to arrange
reasonable accommodations for the classroom and/or testing must contact the appropriate HCC Disability Support Service
(DSS) Counselor at the beginning of each semester. Faculty is authorized to provide only the accommodations requested by
the Disability Support Services Office.
Students who are requesting classroom and/or testing accommodations must first contact the DSS office for assistance prior
to the beginning of each semester: Disability Support Services Offices: Northwest: 713.718.5422
CLASS ATTENDANCE: You are expected to attend all lecture classes and labs. You are also responsible for all
materials covered in either lecture or lab. In the case of your absence, you must contact the instructor to obtain make-up
assignments or arrange make-up testing, either of which can be distributed at the instructor’s discretion. Class attendance is
checked daily.
The instructor has the authority to drop you from the class for excessive absence. You may be dropped from the class
and get an F grade if you are absent more than 12.5% of the instruction hours (lecture and lab). For example: A 12.5%
of 96-hour course, meeting twice per week for 3 hours per class meeting equals 12 hours. If you are absent more than 4
class meetings, you may drop.
WITHDRAWAL - It is your responsibility to withdraw from the class if you cannot complete it. Failure to do so will result in an
F grade. Check calendar for the official last day to withdraw.
Note: Although it is your responsibility to officially withdraw from a class, please discuss with your instructor first.
Consistent class attendance is very important. However, if you have to miss a class for a valid reason, you instructor
may be able to help you catch up with the class. Please let your instructor knows as soon as possible if you have to
miss a class. Valid reason is decided on a case by case basis.
Departments and programs governed by accreditation or certification standards may have different attendance policies.
RELIGIOUS HOLIDAYS: If you observe a religious holiday and miss class, you must notify your instructor in writing two
weeks in advance to arrange to take a test or make up an assignment. A religious holiday is "a holy day observed by a religion
whose place of worship is exempt from property taxation under Section 11.20, Tax Code."
SCHOLASTIC DISHONESTY: Students are responsible for conducting themselves with honor and integrity in fulfilling course
requirements. College System Officials may initiate penalties and/or disciplinary proceedings against a student accused of
scholastic dishonesty.
 "Scholastic dishonesty" includes, but is not limited to, cheating on a test, plagiarism, and collusion.
 "Cheating" on a test includes:
 Copying from another student's test paper;
 Using materials during a test that are not authorized by the person giving the test;
 Collaborating with another student during a test without authority;
 Knowingly using, buying, selling, stealing, transporting, or soliciting in whole or part the contents of an un-administered
test;
