Therefore, thesoftwarehasalltherequiredfeaturesforcreatingaMechanical,Electrical,andPlumbingsystem.Inthischapter,youwill learn tostartAutoCADMEPandusevariouscomponentsdisplayed in theAutoCADMEPinterface.GETTINGSTARTEDWITHAUTOCADMEPWhenyou installAutoCADMEP2015on your system, three shortcuts pointing to theAutoCADMEP2015 - English (Global), AutoCADMEP 2015 - English (US Imperial), and AutoCADMEP 2015 -English(USMetric)willbecreatedonthedesktop.YoucanstartAutoCADMEPbydouble-clickingonanyof these three icons. Ifyoudouble-clickonAutoCADMEP2015-English (US Imperial), theunitsavailable in drawing will be in Inch, Feet, andMile. If you double-click on AutoCADMEP 2015 -English(USMetric), theunitsavailableinthedrawingwillbeinMillimeter,Centimeter,andMeter.Ifyoudouble-clickonAutoCADMEP2015-English(Global),AutoCADMEPwillstartusingtheglobaltemplate.

NoteIn this textbook, the global unit system is followed, so you need to start AutoCADMEP 2015 bydouble-clickontheAutoCADMEP2015-English(Global)iconfromthedesktop.AUTOCADMEPINTERFACECOMPONENTSTheinitialAutoCADMEPinterfacecomprisesofdrawingarea,commandwindow,menubar, titlebar,severaltoolbars,modelandlayouttabs,andStatusBar,refertoFigure1-1.Thetitlebarislocatedonthe

In this area, you can drawobjectsandusethecommands.Todrawtheobjects,youneedtodefinethecoordinatepoints.Positionofthepointingdevice isrepresentedonthescreenbythecursor.There isacoordinatesystemiconat thelowerleftcornerofthedrawingarea.Thedrawingareaalsohasthestandardwindowsbuttonssuchasclose,minimize,andmaximizeonthetoprightcorner.Thesebuttonshavethesamefunctionsasforanyotherstandardwindow.CommandWindowThecommandwindowatthebottomofthedrawingareahasthecommandbarwhereyoucanenterthecommands.Italsodisplaysthesubsequentpromptsequencesandthemessages.Youcanchangethesizeofthe window by placing the cursor on the top edge (double line bar known as the grab bar) and thendragging it. This way you can increase its size to see all the previous commands you have used. Bydefault, the command window displays only three lines. You can also press the F2 key to displayAutoCADTextwindow,whichdisplaysthepreviouscommandsandprompts.

In thisdialogbox, enter thedurationafterwhich the filewillbe savedautomatically in theMinutesbetweensaves textboxintheFileSafetyPrecautionsareaof theOpenandSave tab.Thisduration depends on the power supply, hardware, and type of drawings. AutoCAD MEP saves thedrawingwith the file extension .sv$. You can also change the time interval by using theSAVETIMEsystemvariable.

Tip.Althoughtheautomaticsavefeaturesavesyourdrawinguptoacertaintimeinterval,youshouldnotcompletelydependon itbecause theprocedure forconverting thesv$ file intoadrawing file iscumbersome. Therefore, it is recommended that you save your files regularly using theQSAVE orSAVEAScommands.BACKUPFILESIf a drawing file already exists and you use Save or Save As tool to update the current drawing,AutoCADMEPcreatesabackupfile.AutoCADMEPtakesthepreviouscopyofthedrawingandchangesit from .dwg to .bak.

INTRODUCTIONAutoCAD MEP, a software based on AutoCAD platform, is used to design, draft, and documentelectrical,mechanical,andpipingsystemofbuildings.Thefirststepwhilecreatingsuchasystemis tocreate a project.Thereafter drawings are added to this project to represent various components of thebuilding like electrical system, ducts, and so on. These drawings are then arranged according to theworkflowoftheproject.WORKFLOWWorkflowisasequenceofconnectedstepsrequiredtocreateaspecifictypeofsystem.Itisdependentonthesystemtobecreated.Forexample,foranHVACsystem,theworkflowisshowninFigure2-1.Thestepsinvolvedinthisworkflowarediscussednext.

Figure2-1WorkflowforanHVACsysteminAutoCADMEP

SpecifyingtheHVACParametersIn this step, you need to specify all the parameters required to create an HVAC system. Some of theparameters are duct size, duct rise and drop, flow rate, cut length, and so on. On the basis of theseparameters,thehierarchyofdrawingsinprojectwillbedecided.StartingaProjectInthisstep,youneedtocreateaprojectfiletolinkthedrawingsofasystemtoeachother.Forexample,thedrawingsrelatedtoHVACsystemwillbeinterlinkedandwillbeinthesameproject.Asaresult,youcaneasilymanipulatetheparametersofthesystem.LinkingSystemFiletotheArchitecturalPlanTocreateanHVACsystem,youneedtohaveanarchitecturalplan.Inthisstep,youwilllinktheHVACsystemfiletothearchitecturalplanfileusingthePROJECTNAVIGATOR.Afterthecompletionofthisstep,youcanreroutetheHVAClinesaccordingtothearchitecturalplan.SpecifyingSpacesandZones

In this step, you need to create spaces and zones using the tools available in AutoCADMEP. Thesespaces are used for exporting the building information related to the heating and cooling loads. Thespacesarefurtherdividedintozoneswhichrepresenttheactualheatingandcoolingloads.CalculatingLoadsInthisstep,youneedtocalculatetheheatingandcoolingloadsforthebuilding.ThesecalculationsareperformedbyusingtheanalysistoolsavailableinAutoCADMEP.NoteInthistextbook,theglobalunitsystemisfollowed,thereforeyouneedtostartAutoCADMEP2015bydouble-clickingontheAutoCADMEP2015-English(Global)iconavailableonthedesktop.
