The text concentrates on the concepts and skills neededto sketchand create 2-D drawings and 3-D CAD models.Engineering graphics hasgone through significantchanges in the last decade as a result ofthe use of comput-ers and CAD software. It seems as if some newhardwareor software development has an impact onengineeringgraphics every year. Although these changes areimpor-tant to the subject of technical graphics, there is muchaboutthe subject that has not changed. Engineers still findit necessaryto communicate and interpret design ideasthrough the use ofgraphical methods such as sketches andCAD drawings and models. Aspowerful as todays com-puters and CAD software have become, theyare of littleuse to engineers who do not fully understandfundamentalgraphics communications principles and 3-Dmodelingstrategies, or who lack high-level visualizationskills.
Technical Graphics Communication Bertoline 4th Pdf Download
Graphics communications using engineering drawings andmodels isa languagea clear, precise languagewithdefinite rules that must bemastered if you are to be suc-cessful in engineering design. Onceyou know the lan-guage of graphics communications, it willinfluence theway you think, the way you approach problems.Why?Because humans tend to think using the languages theyknow.Thinking in the language of technical graphics, youwill visualizeproblems more clearly and will use graphicimages to find solutionswith greater ease.
In engineering, 92 percent of the design process isgraphicallybased. The other 8 percent is divided betweenmathematics andwritten and verbal communications.Why? Because graphics serves asthe primary means ofcommunication for the design process. Figure1.1 shows abreakdown of how engineers spend their time. 3-Dmodelingand documentation, along with design model-ing, comprise more than50 percent of the engineers timeand are purely visual and graphicalactivities. Engineeringanalysis depends largely on readingtechnical graphics,and manufacturing engineering and functionaldesign alsorequire the production and reading of graphics.
Technical graphics can also communicate solutions totechnicalproblems. Such technical graphics are producedaccording to certainstandards and conventions so theycan be read and accuratelyinterpreted by anyone who haslearned those standards andconventions.
The precision of technical graphics is aided by tools;some arethousands of years old and still in use today, andothers are as newand rapidly changing as computer-aideddesign/drafting (CAD). Thisbook will introduce you to the
Engineers are creative people who use technical meansto solveproblems. They design products, systems, devices,and structures toimprove our living conditions. Althoughproblem solutions begin withthoughts or images in themind of the designer, presentation devicesand computergraphics hardware and software are powerful toolsforcommunicating those images to others. They can also aidthevisualization process in the mind of the designer. Ascomputergraphics have a greater impact in the field ofengineering,engineers will need an ever-growing under-standing of and facilityin graphics communications.
Figure 1.1 A Total View of Engineering Divided into ItsMajorActivitiesGraphics plays a very important role in all areas ofengineering;for documentation, communications, design, analysis,andmodeling. Each of the activities listed is so heavilyslantedtoward graphics communications that engineering is 92percentgraphically based. (Courtesy of RealD Stereographics)
Just as the graphics language has evolved over the years intoasophisticated set of standards and conventions, so have thetoolsused to graphically communicate technical ideas.Tools are used toproduce three basic types of drawings:freehand sketches, instrumentdrawings, and computerdrawings and models. The tools have evolvedfrom pencils,triangles, scales, and compasses to computer-aided
Toolsdevices used to create engineering drawingsand models,including both handheld and computertools.Applicationsthe varioususes for technical graphicsin engineering design, such asmechanical, electrical,and architectural.
Learning to communicate with drawings is very similarto learningto write or speak in a language. For someoneinexperienced intechnical drawing, the learning process isvery similar to learninga new language. There is a set of rules that must be learned inorder to communicategraphically or when learning a new language.You willsoon find out that graphics is a very effective methodofsupporting the design process.
Figure 2.4 Shaded SketchThis rendered sketch is an example ofthe amount of detail thatcan be used when creating sketches. Thistype of sketch ismore appropriate for technical illustrations thanfor designcommunications. (Irwin drawing contest winner TimBrummett, PurdueUniversity.)
Most projection methods were developed to address theproblem oftrying to represent 3-D images on 2-D media(Figure 2.22).Projection theory and methods have takenhundreds of years toevolve, and engineering and technicalgraphics is heavily dependenton projection theory.
Another way of classifying projections relates to whethertheyuse parallel projection or perspective projection.Multiview,isometric, and oblique multiview projections useparallelprojection, which preserves the true relationships ofan objectsfeatures and edges. This type of projection is thebasis of mostengineering and technical graphics. Perspectiveprojection distortsthe object so that it more closely matcheshow you perceive itvisually.
