CATALOG DESCRIPTION: Introduction to the basic capabilities of a computer-aided drafting (CAD) system. Includes appropriate hardware, software, and applicable commands.

Time: The class is a fully articulated college class in which a student can earn three credits. There are basic requirements to earn such credit. The class requires three 50-minute instructional periods each week for the 15-week semester. Also, an exam period is scheduled during the 16th week. Most people find that at least 3-6 hours of drawing and study outside of class are necessary to be successful with this complex program. Background in engineering, surveying, manual drafting, or previous versions of AutoCAD will probably decrease the time necessary. Skills in keyboarding, Windows, and computers are recommended.

Course Objectives: Knowledge of AutoCAD commands and drawing setup, knowledge of the basic concepts and applications of AutoCAD, an intermediate efficiency using AutoCAD, ability to solve drawing problems of intermediate difficulty using the appropriate tools (commands, help, text, and other references), development of techniques to improve efficiency of drawing, and ability to use a computer system that has the appropriate hardware and software.

Course Objectives for Program Review—Spring 2006: At the end of the course, grades should reflect each student’s attainment of the following skills and concepts:

 Identify a number of applications for AutoCAD’s use. \a,b,c  Explain Cartesian coordinates and that in the AutoCAD Drawing Editor, one draws objects in true size from tiny objects to maps of the whole world. \a,b,c  Use most of the draw and modify commands to input coordinates using several methods of entry and all command syntaxes to solve a variety of drawing problems accurately. \a,b,c  Know the main features of a recent version of AutoCAD. \a,b,c  Create layers and text, simple dimensions, hatches, and blocks. \a,c  Set up a drawing using accepted standards and conventions for mechanical, civil, and architectural drawings. a,c  Define the word VARIABLE and use the command line and dialog boxes to change variables in the drawing session. a,c  On a network, use and store several formats of AutoCAD files. \a  Use options, help, toolbars, shortcut commands, and references in the AutoCAD interface to decrease learning time and increase efficiency when producing drawings. \a,c

Instruction: Instruction is delivered using lectures, discussion, demonstration, handouts showing drawing techniques, hands-on help from the instructor in class and the labs where practical and as time allows, lab aides in the Computer Labs, and occasional student presentation of applications from which the other students can learn. Communication with the instructor is important for all purposes. I believe students learn best when the instructor uses an interactive approach and that much drawing by the student is necessary to learn AutoCAD. Don't fall behind.

Computer Labs: Students using the Computer labs must abide by the Computer Lab Rules. These rules are posted. Students not abiding by the rules may be asked to leave. Times are posted, but keep in mind that classes take precedence over lab use and lab times may change. Over holiday weekends, the open lab is usually closed, so keep this in mind when planning your lab time. CADD lab aides are not available all the time and cannot have long tutorials with one student. Allow plenty of time for technical difficulties. My office hours are posted outside my door.

Grading: Reading, written assignments, and drawings are scheduled on a weekly basis. For weekly classes, assignments are due the next class meeting date at the beginning of class. For Tues./Thurs. or Mon./Weds. classes, assignments are due at the beginning of the first meeting day of the week. Each day the work is late and not approved there will be a 5-point penalty to a maximum of a 25 point penalty. All drawings not turned in will receive a “0” grade. Drawings with a grade of 85 or less may be submitted for redraw. All redraws will be graded on a Redraw/Full Credit/Late basis. If a student receives a "Redraw" grade, the corrections should be made within one week of grading by the instructor. Full credit will be given for perfect work completed on time or for perfect work redrawn within the one-week redraw period. Students are expected to use the labs/tutors as necessary on a consistent basis for help with drawings and redrawings; however, lab aides are not private tutors and cannot assist individual students for long periods of time. For successful completion of the course, it is expected that all class time and at least 3-6 drawing hours outside of class will be necessary.

All drawings and redrawings not completed within the time frame will be graded as a 0-75% depending on quality and overdue time. Also, sets of take-home or class questions will be assigned. To receive a final A grade the student must complete all drawings in a perfect or near- perfect manner within the time allowed (unless otherwise arranged with the instructor), must complete all other assignments in an excellent manner, and must exhibit competency on a final take-home review. Final grades will be weighted based on this scale:

80% - The average of all drawings and written assignments 10% - The final review 10% - Class attendance and participation

At the instructor's discretion and approval, a drawing of medium complexity or a drawing from a person's work may be substituted for the long take-home review. The student will make a

A = 90-100 D = 60-69 B = 80-89 <60 = F C = 70-79 W = Official withdrawal from class by the 13th week Please refer to the catalog for other letter grades possible and for specifics on grade point averages. There are rules governing academic integrity. Punitive measures are described in the Rules and Disciplinary Procedures for Members of the University Community.

Attendance: Attendance is very important to receive all the information necessary to complete the work well and within the time allowed. Approximately forty-five hours of instruction is the standard college requirement to receive three credits. If you need to be absent, call the instructor or send an email message to receive an excused absence. More than two unexcused absences will cause the student's grade to be dropped by one letter. GBC's catalog states that an instructor may drop a student or may apply a punitive grading policy as established by the syllabus. Those who cannot abide by this policy should communicate with the instructor; we like to work with students so students may reach their educational goals. It is the student’s responsibility to make up work missed and to find out what was missed.

If you must withdraw or otherwise change your student status, please do so officially at Student Services. The college catalog specifies rules, regulations, and rights governing student life at GBC.

A grade sheet will be used for feedback on drawings, but assignments are on the following course guide. Study the chapters referenced and complete the exercises as given. Be certain to follow this guide rather than the grade sheet, which is used for redrawing suggestions only.

Evaluation Procedures: Outcomes will be evaluated using a combination of measures:

a. During the course of a semester, weekly increasingly difficult drawing problems which are corrected using instructor comments, redrawn as necessary, and graded.

b. In Week 8 for a Midterm assessment, draw a flow diagram with no dimensions that requires use of all basic draw and modify commands learned.

, AutoCAD Course Outline c. The final assessment is a thorough take-home, open-book exam. Because students’ levels span beginning students to engineers with degrees, with instructor approval, students may substitute one of the following:

o A drawing application of intermediate difficulty that demonstrates competence in the course objectives and goes beyond. This must be submitted both on disc and on a plotted sheet no smaller than ANSI E. We ask permission to display these

o Drawing(s) from the work environment which go far beyond class objectives and from which others may benefit. We ask permission to display these, also.

o Drawing a complex set of mechanical drawings and successfully answering a set of questions about the drawing that require drawing accuracy to several decimal places.

, AutoCAD Course Outline Course Guide

This is a course guide ; assignments and topics may be changed from time-to-time if the instructor feels it would benefit instruction. Selected AutoCAD 2002 features will be introduced as we complete the work. If you miss class, you are responsible for finding out what was covered and assigned. Readings, explanations, and written exercises will be given regularly; however, to benefit instruction, expect variation from the scheduled assignments from time- to-time.
