Course Description:

 

An emphasis will be placed on techniques of computer aided drafting and design, construction of straight and curved lines; orthographic and axonometric views and sections; dimensions, tolerances, and notes; as well as an introduction to the nomenclature associated with CAD.  Basic computer operations involving move, copy, delete, and save are included, and the student will be exposed to drawing manipulation involving translation, rotation, zooming, panning, and windowing.

 

Prerequisites:

 

DFT-102 or DFT-112 or consent of the instructor

Objectives:

 

1.      Construct drawings of primary auxiliary views

2.      Construct drawings of secondary auxiliary views

3.      Construct and solve problems using descriptive geometry

4.      Construct revolution drawings

5.      Construct intersection drawings

General Education Competencies:

In addition to the specific course competencies listed above, students are expected to have, and continue to develop the following general education competencies:

1.      Writing: to communicate effectively using standard written English

2.      Reading: to analyze, summarize, and interpret a variety of reading materials.

3.      Integrated Learning: to think critically and make connection in learning across the disciplines.

4.      Creative Thinking: to elaborate upon knowledge to create new thoughts, process, and products.

5.      Ethics/Values: to demonstrate an awareness of ethical considerations in making value choices.

 

Evaluation of General Education Competencies:

1.      Writing: Students will complete written assignments and possibly answer essay questions in which he/she will demonstrate effective written communication skills using standard English.

2.      Reading: students will be responsible for reading assignments from the text and other sources. Student will be expected to participate in an in-class discussion and answer questions in writing over the reading assignments.

3.      Integrated Learning: Students will utilize the knowledge they acquire throughout this course to make connections between the various disciplines of drafting by applying certain skills such as analysis, discussion, interpretation, and problem solving.

4.      Creative Thinking: students will elaborate on acquired knowledge to create thought processes, and products that are new to the student. This can be

demonstrated raising/answering hypothetical questions and contributing to the

learning process in various ways.

5.      Ethic/Values: Students will demonstrate an understanding of ethical values and consideration by:

a.       Showing commitment and responsibility for their own academic pursuit.

b.      Respecting opinions in contradiction to their own.

c.       Subscribing to a code of courtesy and etiquette in dealing with others.

d.      Understanding what constitutes cheating and plagiarism and avoiding such conduct.

e.       Showing and understanding of ethics as related to Computer Aided Drafting.

f.        Discussing other ethics/values issues.

 

Mandatory Placement Policy:

Students taking the Compass Exam that fail to obtain the minimum required scores as required by the College must take the required remedial courses. Those results that are waived are listed below with requirements listed.

 

Math                30-34   Waived            Supplementary math through Adult Basic Education

Reading            38-41   Waived            Supplementary reading through Adult Basic Education

English 38-69   Waived            Supplementary English through Adult Basic Education

 

Attendance Policy:

All students are expected to attend class. Chronic absenteeism will result in a failing grade. Students with perfect attendance will be given the opportunity of not having to take the final exam.**

 

Work Policies:

All work must be turned in the same week it was assigned.  Work will not be accepted late and there will be no make-up unless the student has an extenuating circumstance, which will be reviewed on an individual basis.  All written work must be typed according to present writing standards.  Students may withdraw 1 week after midterm and still receive a “W”, after that all withdrawals will result in a failing grade.

 

Evaluation:

1.      Lectures are worth 15% (You cannot make this up)

2.      Classroom assignments are worth 30% of the overall grade

3.      Project assignments or writings are worth 15% of the overall grade

4.      Tests are worth 20% of the overall grade

5.      Final exam is worth 20% of the overall grade**(See note above)
