Introduction

The material is carefully developed with the use of industry experts' insights in the presentation. Since CAD has dominated the workplace in the last decade, it became a challenge to academia to provide an engineering graphics class that will prepare the student in both traditional and computer aided drafting methods. The determination of the break point of the topics has been planned to introduce the new technology and at the same time continue the use of traditional parallel technique to further improve the student's skills.

This Course Schedule contains unit-by unit instructions for how to complete the essential course activities. The readings listed for each unit are from the textbook, as are the assigned plates. Review Questions are located in the EGR115 Assignment Materials forum of the EGR 115 Online Conference, and there are also materials related to AutoCAD.  (Click here for instructions on how to log on to the conference)

You are expected to download graphics plates assignments from the Online Conference (Allaire Forums) as noted in the Course Schedule. You may use the Online Conference to submit your Review Questions, or you can submit them to the instructor via e-mail in Word or HTML format. Additional instructional material, answers to frequently asked questions, or other material helpful to your studies may also be developed and available on the Online Conference as the course progresses.

This segment of Engineering Graphics traces the evolution of graphic language. The historical overview will facilitate the learning of graphic communication as an effective means of communicating technical ideas about product designs and processes. This segment also presents the different terms, conventions and standards as applied to engineering graphics.
 

In order to fully understand the importance of engineering graphics, it is necessary to discuss its role in the design process. In this segment of coursework, students will become familiar with the engineering design process. The discussion will describe the use of engineering graphics as a vital link between different engineering and non-technical disciplines.

In this segment of the coursework, students will be exposed to the uses and functions of different drawing instruments including peripherals and components that comprise a CAD system. Though computer aided design and drafting will eventually dominate the production of engineering designs and documentation, the importance of acquiring vital skills using the traditional drafting instruments will be the focus of this unit.
 

The importance of freehand drawing or sketching in engineering and technology cannot be ignored, for it provides a clear picture of the idea. Verbal communication at times becomes cumbersome, while providing a simple sketch on the other hand eliminates miscommunication and ambiguities. Though drawings bridge the communication gap, timeliness is also an important factor. The development of freehand drawing as a skill will be essential to meet the time constraints and further becomes the input for both traditional board drafting and CADD.

The proliferation of CADD at times becomes an excuse to dismiss the importance of developing proper penmanship. This lecture will include traditional lettering conventions, using ANSI Y14.2 as the guide.

The ability to visualize 3D objects from 2D drawings and vice versa will be the focus of this chapter. This chapter will lay the foundation for recognizing different geometric features of 3D objects and their appropriate 2D representations.
 

This part of the lecture series is the cornerstone of engineering graphics. In this segment, graphics primitives will be discussed in detail. The lecture will focus on the different methods of constructing geometric entities, and the major categories of geometric entities. The lecture will conclude with a discussion of the engineering application of geometry.

After learning visualization techniques from the previous chapters, this segment of the lecture series addresses the principles and applications of translating 3D graphics into different 2D graphics. Major topics includes orthographic and multi view projections. It is recommended that students read the materials presented in Chapter 7, Three Dimensional Modeling. The material will be presented in a way that the student will begin to develop skills in creating multiview projections of 3D graphics and also generate a 3D model from the different combinations of multiview projections.

The lecture will use both techniques of drafting to achieve the same drawing. Students will begin to complete the assigned plates using AutoCAD software.
 

This segment of the coursework determines the breakpoint from the traditional board drafting to computer aided design and drafting. The introduction of CADD at this point allows the students to keep their focus on the fundamentals of engineering graphics and learn the basics of CADD. The ability to have the feel and total control in the board drafting shall have given the student enough confidence to venture to different technology in graphics presentation. Students should also be reminded that CADD will not supplant their instrumental drawing practices. Just like the drafting instruments, it is only a tool!

The course will present AutoCAD software as the CADD package for this course. Videotape lectures will include demonstrations and actual generations of drawing. Students are encourage to familiarized themselves with software menus and screen layout provided in the AUTOCAD Reference.

In the segment about multiview projections, students have learned that the regular graphic views are generated parallel to the projection plane. These methods of creating multiview drawings limit the objects that have the principal shape non-parallel to the projection plane. To resolve such a problem, it becomes necessary to create a projection plane parallel to the desired side or surface. Auxiliary views are created to complement external features that are non-parallel to the projection plane.

This segment of the lecture series will present the science of graphical representation and the solution to spatial relationships of different graphics primitives. Knowledge of this subject will facilitate learning engineering mechanics and dynamics.
 

The limitations of multiview drawing should not be ignored. At times, providing three-view drawings will give the user enough understanding of the object being described. In manufacturing, it is essential that each facet of the part being considered for fabrication be described without ambiguity. The multiview drawings are normally complemented with several sectional views. The intent is to describe the part by avoiding the use of hidden lines. Textures are defined by passing section lines in appropriate places.

After learning the different methods of creating drawings it becomes essential to add notations on them. This segment will provide students the proper guidance for adding notations on their drawings. It is essential to follow the conventions, since the drawings are used by different technical personnel.

As part of this lecture series, discussions will focus on the degree of accuracy in manufacturing and the functional requirements and how they are incorporated in drawings. Geometric tolerancing allows the designer to influence the selection of the manufacturing processes.
