Xue  \nDepartment of Mechanical and Manufacturing Engineering, University of Calgary  \nCalgary, Alberta, Canada T2N 1N4  \nE-mail: xue@enme.ucalgary.ca  \nAbstract  \nThis paper introduces our experience of teaching a CAD course in mechanical and manufacturing engineering programs at University of Calgary. Three aspects of the CAD knowledge, including computer graphics theory, practice of CAD systems, and applications of CAD in engineering design and manufacturing, are discussed based on the requirements for the mechanical and manufacturing engineering programs. The various components of a CAD course at University of Calgary, including lectures, laboratories, textbooks, assignments, and course projects, are provided at the end of this paper.  \n1. Introduction  \nDevelopment of CAD tools was started by the pioneer work of the SKETCHPAD project at the MIT for designing an electronic drafting board to replace the conventional mechanical drafting board [1] . In 1970s, considerable theoretical results have been achieved in computer graphics, such as solid modeling, free form curve and surface modeling, and visualization of 3-D geometric objects. In 1980s, commercial CAD systems, such as AutoCAD by Autodesk for 2-D drafting and Pro/Engineer by Parametric Technology Corporation (PTC) for 3-D modeling, were introduced. Today CAD systems are widely used in engineering design and manufacturing, including geometric modeling, structure analysis, motion analysis, CNC machining, rapid prototyping, and so on.  \nThe CAD courses were introduced to mechanical and manufacturing engineering programs in 1980s with the advances of computer hardware and software technologies. Due to the limited functions of CAD systems in late 1980s and early 1990s, most of the efforts in these CAD courses were devoted to the CAD  \ntheory, primarily computer graphics, for satisfying requirements in engineering design and manufacturing. Since many advanced functions, such as finite element analysis (FEA), motion analysis, CNC simulation and machining, and computational fluid dynamics (CFD), have been added to the CAD systems in the past decade, focus of teaching CAD courses has also been shifted from computer graphics to applications of CADin engineering design and manufacturing.  \nPresently CAD is considered as a fundamental component in mechanical and manufacturing engineering programs. CAD is usually introduced through the following three types of courses.  \n• Junior undergraduate course in engineering graphics: to use a CAD system as an electronic drafting tool to practice engineering graphics knowledge.  \n• Senior undergraduate course and junior graduate course in CAD/CAM/CAE: to use a CAD system asa tool for engineering design, manufacturing, and analysis.  \n• Senior graduate course for special purposes: to use and to develop specialized CAD systems for complex shape modeling, customized finite element generation, computer animation, and so on.  \nIn recent years, the following questions are often raised due to the improvement of CAD functions.  \n(1) Should a CAD course be offered in mechanical and manufacturing engineering programs? Two issues are usually considered to decide whether a course should be offered. First the topics in the course have to be essential for the program. Second the materials of the course take systematic approach to learn. For a good CAD system, it takes only days, if not hours, to learn the fundamental functions of 3-D modeling and 2-D drafting.  \nTherefore questions are raised on whether a CAD course should be offered. In other words, are we satisfied if the students have some fundamental knowledge on 3-D and 2-D geometric modeling?  \n(2) What should be offered in a CAD course? Suppose we agree that a CAD course should be offered in the mechanical and manufacturing engineering programs as what has been well accepted by most p","cbCaimoKgqBw01Lc","https://ap.wps.com/l/cbCaimoKgqBw01Lc","pdf",896138,"English","# Abstract\n# 1.
