COURSE DESCRIPTION: Examination of the graphical solution to problems involving points, lines, and planes in space.
TEXT: Applied Descriptive Geometry, newest ddition. (2nd), by Kathryn Holliday-Darr.
Published by Delmar Cengage Learning.
MATERIAL REQUIRED:
French Curve(small)
Scale, metric (triangular)
Set of drawing instruments (minimum set)
3 Drafting pencils, 4H, 2H, and F or B hardness recommended or
Mechanical lead holders (with leads listed above)
or Pentel type pencils (with leads listed above)
Protractor (180 degrees)
30-60 Triangle with 8” legs
45-90 Triangle with 8” legs
Isometric ellipse template
6” bow compass & 6” dividers
COURSE OBJECTIVES: Demonstrate the ability to visualize spatial relationships; develop sequential thinking; set patterns of analysis;
and spatial visualization through problem solving.
1. KNOWLEDGE: a.
b.
c.
d.
e.
Find the point view of a line
The true length view of a line
The edge view of a plane d. the true shape view of a plane
Measure the angle between an oblique line and a plane and between two planes
Determine the slope, bearing, grade, strike, and dip in typical civil engineering, oil field exploration
and mining application problems.
2. SKILLS: a. use graphical techniques for analysis of forces and velocities in structural,
machine design and motion system.
b. determine the piercing points and intersections between lines and planes.
c. construct developments of geometric shapes.
d. to solve typical engineering spacing problems.
3. ATTITUDES/BEHAVIORS:
a. The student will learn to follow instructions as presented in classroom.
b. The student will demonstrate patient.
c. The student will show respect for others.
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
 Knowing how to learn: Uses efficient learning techniques to acquire and apply new knowledge and skills.
 Reasoning: discovers a rule or principle underlying the relationship between two or more objects and applies it when solving a
problem.
 Arithmetic/mathematics: performs basic computations and approaches practical problems by choosing appropriately from a
variety of mathematical techniques.
The student will be presented learning techniques that can be applied to orienting oneself in space in order to ascertain specific data from
geometry and will apply those techniques based on the involved relationships to attain both visual and mathematical solutions to the problem.
Their understanding of these techniques of acquiring data will be measured as a part of the assignments involved in this program
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.
Revised 6/29/2016
Page 2 of 3
 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 or missing more than 4 sessions (3 for Summer).
I (Incomplete) = Fail to submit final project or fail to show up at the final exam
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”.
PROGRAM ACCESSIBILITY (ADA): The Houston Community College, Drafting and Design Technology Program are 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 Northeast College ADA Certification Office,
located in the Northline Mall Campus. For information call Barbara Morris at, 713-718-8148.
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 can not 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 know 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;
 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.

“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.”
