OverviewAs manu ac urers rapidly ransi ion rom D o D CAD in oday’s digi al world, designers are demanding D o enhdesigns and improve communica ion. From websi es o rapid pro o yping, cus omers, designers, and engineers now dep

he la es D modeling ools.

In his paper, we highligh he advan ages o designing wi h SolidWorks® D CAD so ware as well as explaining how oleverage your exis ing D CAD da a once you have decided o go D.

BRIDGING THE WORLDS OF 2D AND3D CAD DESIGN

W H I T E P A P E



Advantages of 3D CAD

As you work wi h D CAD so ware, you will quickly discover ha D enhances noonly he design process, bu also communica ion wi h your cus omers and design

eam. Following are he main advan ages o using SolidWorks D CAD so ware:

Enhance visualization and communicationCAD is all abou communica ing ideas. We live in a D world, so we visualize objec sin he same way. When i comes o communica ing a design, we na urally pre era D image, model, or anima ion over a D echnical drawing. In he D world,designers mus be able o look a hree or our views o a design and men allycombine hem in order o visualize wha ha design will look like in D.

By moving rom D o SolidWorks D design, HSG discovered how improved visualiza ion os erscollabora ion and innova ion.

While engineers and dra ers can unders and a D drawing, your cus omers,salespeople, buyers, and suppliers may nd i much more di cul o comprehend.Looking a a design in D versus D elimina es he need or viewers o havemas ered his echnical knowledge.

Wi h SolidWorks Pro essional so ware, Mul iquip has improved e ciencies in vir ually everydowns ream unc ion in he produc developmen process.

Bridging the Worlds of 2D and 3D CAD Design 2




Rick Morse, owner o Pearce Processing Sys ems in Glouces er, Massachusets,says ha being able o presen his proposals and nished designs in D o hiscus omers makes communica ion much easier han providing hem D drawings.

Morse also makes ex ensive use o D anima ion. The abili y o show his cus omersa “movie” o he machine in ac ion no only communica es how he machine will

unc ion, bu also gives him an edge over o hers who are submiting D drawingsin he quo ing phase. Wi h D images and D anima ions po en ial cus omers eelmore con den in wha Morse will be delivering as a nished produc . Combine his

wi h he abili y o add pho orealis ic nishes o D models, and you can o en ndi di cul o ell i you are looking a a CAD model on a pho ograph o he ac ualphysical machine.

Vermeer uses SolidWorks so ware o check or in er erences and collisions in large assemblydesigns, which range rom 5 o 4, par s.

In addi ion o presen a ion bene i s, D assembly models can be quickly and easily “exploded” o crea e exploded views or echnical illus ra ions and assemblyins ruc ions wi hou requiring any ur her dra ing. And when D drawings areneeded or manu ac uring, D CAD provides au oma ic view crea ion or any Dview needed, including sec ion views and de ailed views.

The abili y o genera e D images and anima ions also makes i easier ocommunica e wi h o hers besides cus omers. Sales, marke ing, ield service,opera ions s a , inancial personnel, and managemen may also ind i challenging

o in erpre a D drawing. Ye hey will readily unders and he design whenpresen ed in D where you can ro a e, zoom, measure, anima e, and even “walk

hrough” your designs.




D CAD so ware allows you o horoughly explore an assembly wi h explode, unexplode, and hidepar s rom views capabili ies.

Eliminate manual updates

In D, you have o manually upda e every drawing view whenever a change occurs.Change one par and you no only have o include ha change in each o he hreedrawing views or he par , you mus also change every view o every assembly inwhich ha par is used.

Rick Morse says he wonders how hey ever made a machine in he pas in D CAD.He spen much o his design ime jus rying o keep all his drawing views up o da eas his designs evolved. Morse rela es ha in designing complex ood processingmachines, his company incorpora es many design changes or bo h machine

unc ion and manu ac uring cos reasons. Because he had o manually con rol hecoordina ion be ween hundreds o drawing views in D CAD, here were housandso oppor uni ies or mis akes. So, elimina ing he need o in erpre he design is oneo he ways ha working in D saves ime.

Consider how many views need o be upda ed manually in D each ime a simplechange is made o your design. A minor change o a dimension on a par riggers aseries o upda es. Firs consider he drawing o he par —all he views, usually aleas hree, mus be modi ed. Then, drawings o he assemblies ha con ain hapar —again, mos likely hree views, mus be upda ed. And wha happens i hapar exis s mul iple imes in an assembly? Also, how can you be sure you upda ed all

he drawings in which ha par is used?

Luckily in SolidWorks so ware, you don’ have o worry abou any o his. En er heconcep o associa ivi y. In SolidWorks so ware, when you change a par model,such as he leng h o he par or hole diame er, or even add a new ea ure o a par ,

he change is au oma ically rippled hrough o every drawing view, every assembly,and anywhere else ha par is used. And when you wan o know wha o her leswill be a ec ed by he change, SolidWorks so ware also provides he abili y oau oma ically rack and iden i y where he par is used—wha subassembly, whahigher level assembly, and wha drawings, so ha you can make sure you aremodi ying only les and designs ha you really wan o modi y.




D drawing views are au oma ically crea ed rom he D model and upda ed whenever he modelis changed.

Reduce errors with interference and collision checkingOn a D drawing, par in er erences are di icul o ind, especially when he designbecomes large and complica ed. In addi ion, because upda es o D ake so much

ime, many users o en ake shor cu s, like changing a dimension on a par wi houupda ing he ac ual size o he model. How many imes have you heard ha “ hedrawing is no o scale”? Add o his he ac ha mul iple designers will be sharing

he assembly design du ies, and he po en ial or in er ering par s almos becomesa cer ain y. Checking D drawings o iden i y possible in er erence issues isex remely ime-consuming, and in er erences inevi ably all hrough he cracks, evenwi h he mos diligen checkers. In SolidWorks so ware, you can elimina e in er erence be ween par s. In er erencechecking is au oma ic, and every par can be checked o see i i in er eres wi hany o her par . In er erence problems are highligh ed, and even he amoun o hein er erence is repor ed. Wi h SolidWorks so ware you can also au oma e heprocess o hole alignmen checking.

Checking in er erence in an assembly ha is s a ic is di icul enough in D, bu ibecomes almos impossible when you are dealing wi h a design ha moves, likea packaging machine, or a piece o au oma ion equipmen . There are vir ually anin ini e number o possibili ies or a collision o occur in designs ha move. In D

here is really no prac ical way o check or a collision. For una ely, SolidWorksso ware has a solu ion or collisions also. In SolidWorks so ware you can “move” your design hrough i s ull range o mo ion while con inuously checking orcollisions be ween par s. When a collision is de ec ed, he mo ion will au oma icallys op, and he in er erence will be highligh ed. SolidWorks so ware even providesan audible sound o le you know when par s in er ere. I you make designs wi hin ernal moving componen s, Collision De ec ion is an invaluable ool o check he

unc ion o your design.




In er erences also resul rom olerancing problems. SolidWorks so ware provideshe abili y o au oma ically check maximum and minimum olerance condi ions wi h

i s TolAnalys ™ unc ionali y, so you can ensure he olerances you are applyingo your par s are appropria e. I even iden i ies which olerances are he larges

con ribu ors o he olerance s ack-up problem, hereby saving you ime in rying oigure ou which olerances o igh en, or which dimensioning schemes o change.

When i and unc ion errors go down, e iciency goes up, and you reduce ime,labor, and ma erial cos s.

SolidWorks so ware checks hole alignmen au oma ically.

Au oma ic Sys ems Inc. (ASI) in Kansas Ci y, Missouri, manu ac ures a wide rangeo indus rial ma erial-handling equipmen o move every hing rom coal o carbodies. Wayne Ti any, senior machine designer, explains hey o en deal wi h

large machine designs ha require complica ed ma erial handling pa hs. He s a esha here is no reasonable way he can valida e ha his designs will oge herand unc ion properly i he is using D. Ca ching and correc ing in er erences andcollisions in D is invaluable. I hese in er erence and collision problems were nopicked up un il nal assembly and es , i could cos he company or imesas much o x he problem, and o course i would mos likely impac delivery o

he machine o he cus omer. Ul ima ely, says Ti any, “SolidWorks so ware savesour company subs an ial money and ime by ca ching problems be ore hey go omanu ac uring— hese are problems ha we had di cul y nding be ore in D.”




Reuse existing designsTwo unique aspec s o SolidWorks so ware allow you o make easy and ex ensivereuse o exis ing designs: associa ivi y and modi abili y. As discussed earlier, “associa ivi y” means when you change a design model, he change au oma icallyripples hrough o all he o her places where ha model is used— he drawings,higher level assemblies, and more. By “modi abili y” we mean you can change apar by clicking and changing a dimension and all o her geome ry on ha parresizes appropria ely and au oma ically. For example, i you have modeled a ve-inch-long pla e wi h holes dimensioned one inch rom ei her end, and hen click on

he ve inch dimension and change i o inches, he hole loca ion would upda e,bu he holes would s ill be one inch rom ei her end o he par . As you can seerom his example, SolidWorks so ware also allows you o cap ure your design

in en , ano her very impor an aspec o designing in D. The design “in en ” in hisexample is ha you always wan he holes o be one inch rom he ends o he parno mater how long he par is.

Wi h SolidWorks so ware you can speed he crea ion o mul iple con igura ions.

Associa ivi y and modi abili y le you reuse exis ing designs o crea e new versionsor con gura ions easily. You can readily crea e mul iple new con gura ions o asingle par by varying par icular dimensions and ea ures. As an example, you couldmake one socke head cap screw and hen make every leng h and diame er varia ion

rom ha one design jus by changing dimensions. Likewise, you could make anen ire ca alog o screws rom one par by also varying hread pi ch, head ype, andma erial as well as leng h and diame er.

Accelerate development cycles with virtual testing and optimization

Speeding up a design cycle depends on more ac ors han simply s reamlininghe ini ial par or assembly design. Ano her major bene i wi h D modeling is heinsigh i o ers hrough vir ual es ing, analysis, and op imiza ion, which akemany orms.

Ti any apprecia es ha working in SolidWorks so ware allows him o apply mo iono he par s o an assembly and quickly evalua e many di eren designs agains

opera ional requiremen s. Designers can assign a ma erial ype o a par andiden i y he mass proper ies, including weigh and cen er o gravi y.

SolidWorks so ware provides an array o simula ion and op imiza ion ools o help you calcula eorces due o mo ion, par s ress, and de lec ion as well as vibra ion, low, and e ec s oempera ure.




In addi ion he mo ion simula ion capabili y ound in SolidWorks so ware allowsyou o evalua e he e ec s o di eren mo or per ormance curves, ric ion, springs,gravi y, and o her physical charac eris ics o a design. So ra her han jus runningan anima ion o he machine in mo ion, you can simula e wha really is happeningin your design. The mo ion simula ion au oma ically calcula es orces on cri icalcomponen s, like bearings, bushings, and linkages. This in orma ion is hen used ocalcula e par s reng hs, defec ion, a igue, and sa e y ac ors. Thermal, vibra ion,and fow analysis are also provided direc ly inside SolidWorks so ware so ha yourdesign can be op imized. In his way, SolidWorks so ware can be used o solve

ypical design problems, such as: How much weigh can I remove rom his par yes ill have i unc ion wi hin a cer ain ac or o sa e y? Will he par bend oo muchi i is made rom a di eren ma erial? In an elec ronic enclosure, will a speci ccomponen overhea rom lack o airfow?

Design for manufacturingMany o he new manu ac uring echnologies rely on he availabili y o a D CADmodel as a s ar ing poin . For example, hree-axis and up NC programming, rapidpro o yping, mold design, and even shee -me al manu ac uring now require Dmodels ha can be re erenced o crea e NC oolpa hs, SLA models, and shee me al

More and more companies are urning o rapid pro o yping and manu ac uring oreduce he urnaround ime or bo h pro o ype par s and cus omized inal par s,such as hearing aid shells. These rapid sys ems opera e rom D modeling inpugenera ed in s andard empla e library (STL) orma —a ile orma ha you canou pu rom your D CAD model by simply saving your model in ha orma .

I a manu ac urer has o “rebuild” your D design in D, wo problems arise. Firs ,he remodeling is adding an ex ra s ep o he manu ac uring process, which akes

ex ra ime. Many shops ha require D CAD models will pu D jobs a he back ohe queue because o he work required o conver your D design o D. To mos

manu ac urers his is jus addi ional prep work be ore geting o he manu ac uringprocess. Manu ac urers wan heir shops running a capaci y, prep work cos s hemmachining ime, and hey will charge you, he cus omer, or ha ime los o prep.The second problem ha arises is ha he person making he D model can makea mis ake in conver ing your D design o D; his means he par delivered o youmay no mee your design requiremen s, which can ul ima ely a ec he delivery oyour produc . By working in D rom he s ar , you can genera e les ha are ready

o go direc ly o manu ac uring opera ions ha require D CAD models.

In many cases, D drawings are no even required or manu ac uring. For example,SolidWorks so ware can ou pu he D model comple e wi h de ailed dimensioningand olerancing in orma ion as well as no es. In his way, all he da a and no esneeded o manu ac ure he par are included direc ly in he D CAD model.

SolidWorks so ware’s DimXper (dimensioning exper ) au oma ically dimensionsand olerances he D model so ha i is ready or manu ac uring. The buil -in

in elligence o DimXper allows users o au oma ically dimension models per heASME Y 4.5M- 994 s andard or “Dimensioning and Tolerancing,” as well as displayhe dimensions in D per ASME Y 4.4 - , “Digi al Produc De ni ion Da a

Prac ices.” DimXper even has a check o ell he designer when he model is ullydimensioned and oleranced and ready or he shop. Botom line— D par s anddrawings go o he shop foor more correc and more comple e, and machinis sspend less ime asking engineers and designers ques ions abou incomple emanu ac uring drawings, and more ime machining.




Wi h SolidWorks so ware you can au oma ically dimension D models according o indus rys andards.

Wi h SolidWorks so ware, design- or-manu ac uring (DFM) becomes more han

Buil -in manu ac uring in elligence (called DFMXpress) direc s heso ware o check or ea ures ha are expensive or impossible o manu ac ure.These ea ures are highligh ed, and he user is provided an in erac ive lis o heproblems uncovered. Communica ion be ween manu ac uring and engineering is alsogrea ly improved hrough he use o D.

There is a wide range o D digi izing and inspec ion equipmen ha also requiresD CAD models. Wi h he comple e de ails a hand in he D CAD model, you can

Conclusion

As ou lined in his paper, D CAD design has many inheren bene s over workingin D. Produc visualiza ion and presen a ion are improved, par s and drawingviews upda e au oma ically and accura ely, and in er erence and collision checkingprovides an au oma ed, error- ree way o check or in er erences and collisionsbe ore manu ac uring he produc . In addi ion, D does no have o be an all-or-no hing process. You can keep exis ing designs in D, and hen ransi ion hem asneeded in o he D sys em.

However, wo ac s are clear: Firs , he world o design and manu ac uring isde ni ely ransi ioning o D; and second, cus omers and designers are alldemanding D o enhance design and communica ion. Organic shapes, so prevalenin he design o consumer produc s, rom cars o cell phones, are much easier

o model and manu ac ure in D. And wi h he olerances expec ed rom oday’sconsumer produc and au omo ive designs, D sec ions are now unaccep able orde ning hese organic shapes because D does no provide enough sur ace con rolbe ween sec ions.

For una ely, colleges, echnical schools, and high schools are responding o he needor engineers and designers rained in D CAD. For more han 5 years, reques sor D CAD raining have been ou pacing reques s or D CAD raining. This has

resul ed in a large pool o new and experienced designers and engineers amiliarwi h D CAD, who can be ound anywhere in he world. For your exis ing employees,raining op ions are available in all orms, rom book- o web-based o classroomraining. You can pick he ime, orma , and leng h o raining you wan , and a course

will be available o your schedule and budge .

Finally, D modeling brea hes new li e in o your curren design process, atrac sand re ains designers and engineers eager o use he la es design ools, and evenimproves your company image o cus omers and vendors. I is a rare business oday

ha can unc ion produc ively wi hou email and websi es— D design is ano her bigs ep o opera ing ully in his increasingly digi al world.
