COURSE OBJECTIVE:-
Drawingissaid to be the language of engineers.All material objectshave ashape and
form,whichcan be representedbyacombinationof knowngeometrical figures.Any
constructionor fabricationbe itbe a building,afactoryor a machine hasto beginwith
a drawingwhichformsthe basisand guide toget the workdone.
Drawingiscommonlyusedmode of communicationinthe engineeringindustry.Proper
exposure todrawinghelpsthe studentstotranslate differentideasintopractice.
Withthese objectives inview the followingtopicshave beenprescribed:
