Course Rationale:

Study of detail drawings with dimensioning and tolerances, sectioning techniques, orthographic projection, and pictorial drawings.

Topics covered include: Geometric Dimensioning and Tolerancing techniques, the ASME Y14.5M-2009 dimensioning standard, pictorial drawings, auxiliary views, sections, fasteners, and the creation of assembly and detail drawings.  Students will use Inventor to create .IPT, .IAM, and .IDW file types.

Course Description:

Introduction to the principles of drafting to include traditional and CAD techniques, drafting standards, multiview drawing, dimensioning, isometric drawing, sections, auxiliary views, mechanical working drawings, architectural working drawings, and 3D modeling basics. This class serves as the A&E CAD department's introductory CAD class.


Required Text, Materials, and Prerequisites

Text:     Student guide and or handouts furnished by instructor.

Tools/Materials:    Sketching pencil, highlighter pen, and 3-ring binder is recommended.

Prerequisites:  DFTG 1405 or departmental approval.


ACC Email and Blackboard

ACC Email

All communication to students will be sent solely to the student’s ACCmail account, with the expectation that such communications will be read in a timely fashion. ACC will send important information and will notify you of any college related emergencies using this account.  Students should expect to receive email communication from their instructor using this account unless other arrangements have been made.  Likewise, students should use their ACCmail account when communicating with instructors and staff.  Instructions for activating an ACCmail account can be found at http://www.austincc.edu/accmail/index.php.

Blackboard (Bb)
Blackboard will be used for major portions of this course to include but not limited to:

  • Distribution of handouts and readings
  • Submissions of assignments and activities
  • Grading

As instructed by your professor, students will be required to access instructional materials via Blackboard.

Student Learning Outcomes/Learning Objectives

 Course Outcomes:  At the completion of this course, the student will have demonstrated the ability to:

  • Prepare free-hand multiview sketches of objects assigned by the instructor.
  • Create 3D models of machine parts utilizing Inventor software
  • Utilize Inventor to prepare and print mechanical detail and assembly drawings derived from 3D part files.
  • Fully dimension detail drawings in a manner that is in compliance with the ASME Y14.5-2009 dimensioning standard.
  • Prepare section views of  machine parts that comply with the ASME Y14.3-2003 standard.
  • Prepare auxiliary views of machine parts with Inventor that comply with the ASME Y14.3-2003 standard.
  • Utilize Inventor to prepare multi-sheet working drawings for a mechanical assembly that comply with the ASME Y14.34-2008 standard.
  • Apply Geometric Dimensioning and Tolerancing techniques to machine parts in a manner that complys with the ASME Y14.5-2009 standard.
  • Specify and depict threads, fasteners and other hardware in a mechanical assembly.
  • Design and document a consumer product (as defined by the instructor) that follows the classical design model (problem identification, ideation, analysis and refinement, decision and implementation) from conception through working drawings.

Learning Objectives:

Introduce students to the principals of mechanical drawing employing Computer-Aided-Drafting techniques. Demonstrate and explain the theory and practice of dimensioning and tolerancing. Explain the importance of standards (ASME and ISO) in the modern engineering graphics environment.   Demonstrate the creation of 3D geometry and solid modeling techniques using parametric solid modeling software (Inventor). Demonstrate the techniques of specifying threads and fasteners.

Describe the theory and techniques for creating detail and assembly drawings of complex machines. Present a model for the design process (problem identification, ideation, analysis and refinement, decision and implementation) from conception through working drawings.


Grading and Attendance Policy

Grade Determination*

Daily Work 60%

Drawing assignments, quizzes, class participation (see departmental policy on absences), etc.

Design Project 15%

Students will plan and document the design of a simple device or object within the parameters and instructions presented by the instructor.

Capstone Project 25%

Students will create a portfolio-quality set of detail and assembly drawings for a complex machine as assigned by instructor.

Note:  *The final course average will be reduced by 1 point for each unexcusedabsence.

ATTENDANCE:

Regular and timely class participation in discussions and completion of work is expected of all students.  If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class. Students accruing more than two (2) UNEXCUSED absences may be withdrawn from the course at the instructor's discretion.  Students may make-up absences by attending other classes.  It is the student's responsibility to inform instructor when circumstances prevent him/her from attending class.   An instructor may lower a student’s final grade for a course due to excessive absences.

In the event the college or campus closes due to unforeseen circumstances (for example, severe weather or other emergency), the student is responsible for communicating with their professor during the closure and completing any assignments or other activities designated by their professor as a result of class sessions being missed.


Open Labs and Instructional Methodology

INSTRUCTIONAL METHODOLOGY

This course is taught in the classroom in a lecture/laboratory format. The lecture will generally introduce concepts and skills, which will then be developed and applied in the laboratory.

 

OPEN LABS

Hours for the open lab will coincide with the tutoring schedule which will be posted during the first week or two of the semester. You may not be able to complete all the assignments in class, so the open lab is one of your best opportunities to get help in finishing the lab exercises.
