CaddyStep1 Beginbysketchingaline, snappedtotheorigin.

CaddyStep2 Dragthelineupwardand snapALONGY.

CaddyStep3 Createanotherline, startingattheorigin. HittheTABkeytotoggle totheYZplane. SnapthislineALONGZ.

CaddyStep4 Addathirdline. Snaptotheorigin. HittheTABkeytotoggle totheZX(orXY)plane. SnapALONGX.

CaddyStep5 Addafourthline Startfromtheendpointof theexistingline. SnapALONGX. Makeitapproximatelythe samelengthasthe previousline.

CaddyStep6 Sketchafifthline. Snapfromendpointto endpointoftheexisting lines.

CaddyStep7 Addarelation. SetthislinetobeALONG Z. Thisensuresthebaseis rectangular.

CaddyStep8 Sketchanotherline. Snaptotheendpointof theexistinglines. HittheTABkeytotoggle totheXYplane. SnapALONGY.

CaddyStep9 Continueasecondline segment. CreateitintheXYplane, atanangleasshown.

CaddyStep10 Continuewithanotherline segment. SnapALONGY.

CaddyStep11 SketchaTangentArc. Beginattheendpointof theexistingline. Makesureyouarestillin theXYplane. Createanarcabout90 degrees,ending approximatelyabovethe origin.

CaddyStep12 Draganddropthe endpointoftheexisting linetoclosethecontourto thearc. Ifnecessary,dragthefree endpointofthearctoget itcloser. Youcouldalsoselectboth endpointsandadda MERGErelationship.

CaddyStep13 Addarelation. Makethecenterpointof thearcCOINCIDENTtothe line.

CaddyStep14 Selectthefirstthreelines drawn,andmakethem intoConstruction Geometry.

CaddyStep15 Addonefinallinetodefine theshape. Beginattheinsidecorner ofthetwoexistinglines. Snaptheendpoint COINCIDENTtothetall constructionline. SnaporaddanALONGX relationshiptothisfinal line.

CaddyStep16 Adddimensionstofully definetheshape. Wherepossible,dimension toalineinsteadofa vertex,tobettercontrol theorientationofthe parameter.

CaddyStep17 UsetheSketchFillettool toaddR3.00filletstotwo corners.

CaddyStep18 UsetheSketchFillettool toaddtwomorefillets, thistimeR0.75,totwo morecorners. Notethatthefilletsdonot needtolieinthesame plane.

Example2:Handlebars WorkingwithSketch Points. Addingdimensionsto referenceplanes. Workingwithrectanglesin 3D. Creating3Dconstructions tocapturedesignintent. DimensioningtoSketch Filletsina3DSketch. UsingtheSelection Managerforchoosinga sweeppath.

HandlebarsStep1 Createanewpart. Insertanew3DSketch. SwitchtoIsometricview. CreateaSketchPointat anyrandomlocation. Edittheparametersinthe PropertyManagerto positionthepoint precisely: X=14in. Y=12in. Z=6in.

HandlebarsStep2 Toproperlyconstrainthe point,adddimensions. The3DSketchallowsyou todimensionfrom referenceplanestosketch points. Thismethodlocksinthe desiredorientation. Createthreedimensions, onetoeachofthethree defaultreferenceplanes (Front,Top,Right). Keepthevaluesthat appear,sincetheyare correct.

HandlebarsStep3 SwitchtoaTopview. Noticetheworkplane automaticallyswitchesto XZtomatchtheview. SketchalineALONGX, about3incheslongfrom theorigin.

HandlebarsStep4 Sketchanotherlinewhile intheTopview. Beginatthe3DSketch Point. Anglethelineslightly towardtheorigin.

HandlebarsStep5 SwitchtoaFrontview. Grabtheendoftheline youjustdrew,anddragit upwardabit. Nextwewillhavetofigure outhowtoconstrainthe compoundangleofthis line.

HandlebarsStep6 Addonemorelineto connecttheendpointsof thetwoexistinglines. Noticetheyellow wireframeboxthathelps indicatethatthislineisat acompoundanglethrough 3Dspace.

HandlebarsStep7 Toconstrainthe handlegrip,wewillmakea constructionbox. BeginwithalineALONGX.

HandlebarsStep8 TurnontheRectangletool. Starttherectangleatthe endpointofthelineyou justdrew. Asyoucreatethe rectangle,youcantoggle theTABkeyuntilyouare workingintheYZplane.

HandlebarsStep9 Selectthefourlinesofthe rectangleandmakethem constructiongeometry.

HandlebarsStep10 Createtwomore constructionlines,toform thediagonalsofthe constructionbox. OnelineisintheXZplane. TheotherlineisintheXY plane. Wewillbeableto dimensiontheanglesthese linesform,inthecorrect 3Dorientation.

HandlebarsStep11 Noticethattherectangleis madewithPerpendicular andParallelrelationships. ThelocationintheXZ planewasnotcaptured automaticallyby SolidWorks. Selectthebottomsideof therectangleandsetit ALONGZ. Selectanothersideandset ittobeALONGY.

HandlebarsStep12 Nowwecanadd dimensions. Constraintheangleinthe XYplanetobe10degrees.

HandlebarsStep13 Constraintheangleinthe XZplanetobe20degrees.

HandlebarsStep14 Selectthefarcornerofthe constructionboxandmake itCOINCIDENTtothe angledlineofthe handlegrip. Thiscapturesthedesired designintentofthe handlegripscompound angle.

HandlebarsStep15 AddR3.0filletstothetwo sharpcornersofthe handlebar. SwitchtoaFrontview.

HandlebarsStep16 Todimensionthestraight portionneartheorigin, youmustselectthe endpointsoftheline. Ifyouselecttheline,the dimensionwouldbe createdtothevirtual sharp,whichisnotwhat wewantinthiscase. Makethestraightportion 1.00long.

HandlebarsStep17 Usinga3DSketch,its easytodeterminethe locationofa12in. crossbar. Createanotherline, beginningatthelarge slantedlineofthe handlebar,snapping ALONGX. Endthelineabovethe origin.

HandlebarsStep18 Selecttheendpointofthe lineandtheRight referenceplane. AddanONSURFACE relation. Thisissimilartoa coincidentrelationship.It isusedtokeep3Dsketch entitiesconstrainedtoa planeormodelface.
