EachdrawingtaskrequiredmanycommonAutoCADcommands.Buteachwasselectedbecausecertain

aspectsofthedrawingwouldexposethepotentialtimesavingsthatcouldbeachievedbyusingfeaturesand

DrawingTask#1

Thefirstdrawingrepresentsatypicalthree‐dimensionalmechanicalpartthatmightbeproducedusing

AutoCAD—awheelhub.Althoughrelativelysimpleatfirstglance,thewheelhubisactuallyquitecomplexand

includesanumberofcomplexshapesthatwouldrequireextrusions,lofts,chamfersandfilletsaswellasthe

use

ofmultipleBooleanunionandsubtractoperationsandmultipleusercoordinatesystemsorworkplanes.

Oncetheactualthree‐dimensionalmodelwascreated,thetaskscenariorequiredthecreationofapaper

spacelayoutonwhichtraditionaltop,front,andsideviewswouldbecreatedandproperlyorientedand

displayed

atastandardscale,alongwithanisometricviewofthemodel.Oncethisstepwascompleted,

dimensionsandnoteswereaddedtothewheelhubdrawing.Then,severalelementsofthethree‐dimensional

modelwererevisedandthevariousviewsupdatedtoreflectthosechanges.Figure1showsthecompleted

BecauseofthenewfeaturesavailableinAutoCAD2011comparedtoAutoCAD2008,Ianticipatedproductivity

improvementsinanumberofareas:

• SettinguplayerswouldbefasterinAutoCAD2011becausetheLayerPropertiesManagerisanon‐

modalpalettecomparedtoadialogbox

inAutoCAD2008.

• Actualdrawingandeditingtaskswouldbefasterbecausetheribboninterfaceismoreintuitiveand

putscommandswherethey’remoreeasilyaccessed.

• Navigatingwithinthe3DmodelwouldbemuchfasterandmoreintuitiveinAutoCAD2011thanksto

theavailabilityoftheViewCube,which

isnotavailableinAutoCAD2008.
