Course Objectives:

This course is an exposure to computer-aided drafting (CAD) that uses a commercial CAE package to demonstrate the various concepts.

The specific application that will be emphasized in this course is drafting. Drafting techniques allow the engineer to communicate detailed creation and/or assembly information in a recognized, unambigous and standard manner. The course will begin with students sketching three-dimensional objects and will end with a demonstration of parametric feature-based solid modeling and 3-D printing of a mechanical object. Although there will be lectures and assignments on three-dimensional modeling, the core of this introductory course will be on generating two-dimensional drawings of mechanical components.

By the end of the course, each student should be able to:

  • describe the difference between computer-aided engineering and computer-aided drafting;
  • generate sketches of three-dimensional objects;
  • define the parts to an engineering drawing;
  • explain the difference between assembly, layout and detailed engineering drawings;
  • create orthographic projections of three-dimensional mechanical objects;
  • create isometric and perspective views of three-dimensional mechanical objects;
  • create section views of three-dimensional objects;
  • apply basic dimensioning and tolerancing to an engineering drawing;
  • be able to recognize geometric tolerancing on an engineering drawing;
  • explain the physical necessity for tolerances;
  • learn to apply drafting techniques on a commercial CAE package:
    • opening and saving,
    • setting up a template,
    • use absolute and relative, Cartesian and polar coordinate systems,
    • explain and use World and User drawing coordinates,
    • create precision drawings,
    • create drawing entities,
    • edit a drawing,
    • create multiple views: orthographic and isometric,
    • add dimensions and tolerances,
    • recognize geometric tolerances,
    • create a drawing package for a particular mechanical object = assembly, layout and detailed engineering drawings,
    • create a solid model,

Prerequisites:  A basic course in drafting.


Homework:

Homework assignments will be given periodically, and will be assigned during class on Wednesdays.   All assignments will be due the following Wednesdays at the beginning of class.  Late assignments not handed in at the beginning of class will be accepted, but will be penalized 25% per day.
