Revised Aug 25.2013
PREREQUISITE: DFTG 1305
COURSE DESCRIPTION: An intermediate course covering detail drawings with proper dimensioning and tolerances, use of sectioning
techniques, common fasteners, isometric and oblique drawings, including bill of materials.
TEXTBOOKS:
 “Technical Drawing with Engineering Graphics” by Gieseck, 14th edition.
COURSE MATERIALS: Same as DFTG 1305 Technical Drafting. However, students are allowed to submit their assignments by a PDF
file of the CAD software.
LEARNING OUTCOMES/OBJECTIVES:
This course is designed to be a continuation of DFTG 1305 Technical Drafting, and to prepare the student for entry into any one of the (4)
specialization areas within the AAS degree curriculum.
KNOWLEDGE:
a. Identify the various lines used on an engineering drawing
b. Define common geometric shapes
c. Application of the basic rules of dimensioning for part manufacture
SKILLS: a. Produce free-hand sketches
b. Create views of an object using orthographic projection
c. Create isometric drawings with dimensions from given orthographic views
d. Draw and dimension moderate mechanical parts from given isometric views
e. Draw isometric, oblique and perspective views of objects
f. Draw sectional views of an object
g. Draw auxiliary views and revolutions of inclined surfaces
h. Determine the characteristic of fasteners.
LAB REQUIREMENTS: Student can use computer at the labs or at home of his/her choice. The labs to be opened if there is a class in
session. If the lab is being used by other class, student is encouraged to ask the instructor before using the available computer. Lab
assistants, if any, are also available for technical help.
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 two 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.
Note: Students are required to initial his/her name on the provided form (Green Form) upon showing up to the class.
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. Reduction of points could be applied to late
submissions. In general, a minus 5% would be applied to every late week.
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 are 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”.
PROGRAM ACCESSIBILITY (ADA): The Houston Community College, Drafting and Design Technology Program is committed to
making all aspects of the program accessible to individuals with disabilities. Students with disabilities, as defined by the American with
Disabilities Act (ADA), are required to obtain certification of their impairment through the College ADA Certification Office. For
information contact the front office of the campus.
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 absences, that is, you may be dropped from a course after
accumulating absences in excess of 12.5 percent of the total hours of instruction (lecture and lab).
For example: - A 3 credit hour lecture/lab class meeting 6 hours per week – 2 absences (12 hrs.) is 12.5% of the class.
- A 3 credit hour lecture/lab class meeting 3 hours x2 times per week – 4 absences (12 hrs.) is 12.5% of the class.
Administrative drops are at the discretion of the instructor. It is your responsibility to drop a course, should you choose not to complete it.
Failure to withdraw officially will result in you receiving a grade of “F” in the course.
Note: Although it is your responsibility to officially withdraw from a course, it is always a good idea to discuss any attendance problems with your
instructor first. Class attendance is very important, but your instructor may be able to help you catch up. If you become ill or know you are going to miss class
for some reason, tell your instructor as soon as possible.
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;
 Bribing another person to obtain a test that is to be administered.
"Plagiarism" means the misuse of another's work and the deliberate incorporation of that work into work you offer for credit.
"Collusion" means the unauthorized collaboration with another person in preparing work offered for credit.
Determination of scholastic dishonesty will be at the discretion of the instructor.
Reference the following web link for additional information: http://northwest.hccs.edu
*The Final Examination Date & Time:
Will be notified by the instructor.
“Notice: Students who repeat a course three or more times may soon face significant tuition/fee increases at HCC and other Texas public
colleges and universities. If you are considering course withdrawal because you are not earning passing grades, confer with your
instructor/counselor as early as possible about your study habits, reading and writing homework, test-taking skills, attendance, course
participation, and opportunities for tutoring or other assistance that might be available.”
EGLS3 -- Evaluation for Greater Learning Student Survey System (since Fall.2011)
At Houston Community College, professors believe that thoughtful student feedback is necessary to improve teaching and learning. During a
designated time, you will be asked to answer a short online survey of research-based questions related to instruction. The anonymous results
of the survey will be made available to your professors and division chairs for continual improvement of instruction
