Entering the Generative Shape DesignWorkbenchThis first task shows you how to enter theGenerative Shape Design workbench and opena wireframe design part.Before starting this scenario, you should be familiarwith the basic commands common to allworkbenches. These are described in theInfrastructure User's Guide.1.Select Shape-> Generative Shape Designfrom the Start menu.The Shape Design workbench is displayed.The New Part name dialog box mayappear depending on the way youcustomized your session. It provides afield for entering the name you wish toassign to the part, an option thatenables hybrid design an two otheroptions to insert a geometrical setand/or an ordered geometrical set inthe part to be created.If you select Enable hybrid design, thecapability then applies to all the bodiesyou will create in your CATIA session(and not only to the new CATPartdocument you are opening).Consequently, if your session containsCATPart documents already includingtraditional bodies, the new bodies youwill create subsequently in thesedocuments will possibly includewireframe and surface elements.To facilitate your design, It is thereforerecommended that you do not changethis setting during your session.For more information, refer to the PartDocument chapter in Customizingsection of the Part Designdocumentation.2.Select File -> Open and navigate to thesamples directory.3.Select theGettingStartedShapeDesign.CATPartdocument.A wireframe design part is displayed:o Y ou canaddtheGenerativeShapeDesignworkbenchto yourFavorites,usingtheTools->Customizeitem.Formoreinformation,referto theInfrastructureUser'sGuide.o If youwish tousethewholescreenspacefor thegeometry,remove thespecificationtree byselecting theView->Specificationsc ommand orpressing F3. Lofting, Offsetting and IntersectingThis task shows you how to create amulti-sections and an offset surfaces as well as an intersection.1.Click the Multi-sections Surface icon.The Multi-sections Surface Definitiondialog box appears.2.Select the two section curves.3.Click within the Guides window thenselect the two guide curves.4.Click OK to create the multi-sectionssurface.5.Click the Offset icon.6.Select the multi-sections surface.7.Enter an offset value of 2mm.The offset surface is displayed normal to the multi-sections surface.8.Click OK to create the offset surface.9.Click the Intersection icon.The Intersection dialog box appears.10.Select the offset surface then the firstplane (Plane.2) to create theintersection between these twoelements.11.Click OK in the dialog box.The created elements are added to the specification tree:12.Splitting, Lofting and FilletingThis task shows how to split surfaces then create a multi-sections surface and two fillets.1.Click the Split icon.The Split Definition dialog box appears.2.Select the offset surface by clicking onthe portion that you want to keep afterthe split.3.Select the first plane (Plane.2) ascutting element.4.Click OK to split the surface.5.Repeat the previous operations byselecting the multi-sections surfacethen the second plane (Plane.3) todefine the intersection first, then to cut the surface.6.Click OK to split the surface.7.Click the Multi-sections Surface icon.The Multi-sections Surface Definitiondialog box appears.8.Select the intersection edges of the twosplit surfaces as sections.9.Click OK to create the multi-sectionssurface between the two split surfaces.10.Click the Shape Filleticon.The Fillet Definition dialog box appears.11.Select the first split surface as the firstsupport element (Split.3).12.Select the multi-sections surface youjust created as the second supportelement (Multi-sections Surface.3). 13.Enter a fillet radius of 3mm.The orientations of the surfaces areshown by means of arrows.14.Make sure that the surface orientationsare correct (arrows pointing down) thenclick OK to create the first fillet surface.15.Repeat the filleting operation, clickingthe icon, then selecting the second split surface as the first support element.16.Select the previously created filletedsurface as the second support element.17.Enter a fillet radius of 3mm.18.Make sure that the surface orientationsare correct (arrows pointing up) thenclick OK to create the second filletedsurface.The created elements are added to the specification tree:Sweeping and FilletingThis task shows how to create swept surfacesand fillets on both sides of the part.You will use the profile element on the side ofthe part for this. In this task you will alsocreate a symmetrical profile element on theopposite side of the part.1.Click the Swept Surface icon.The Swept Surface Definition dialogbox appears.2.Click the Explicit sweep icon.3.Select the profile element (Corner.1).4.Select the guide curve (Guide.1).5.Select the central curve (Spline.1) asthe spine.6.Click OK to create the swept surface.7.Click the Symmetryicon.The Symmetry Definition dialog box appears.8.Select the profile element to betransformed by symmetry.9.Select the YZ plane as referenceelement.10.Click OK to create the symmetricalprofile element.11.Click the Sweep iconagain.12.Select the profile (Symmetry.3) andthe guide curve (Guide.2).13.Select the central curve (Spline.1) asthe spine.14.Click OK to create the swept surface.15.To create a fillet between the sideportion and the central part click theShape Filleticon.16.Select the side sweep element and thecentral portion of the part, then enter a fillet radius of 1mm (make sure thearrows are pointing up).17.Click Preview to preview the fillet, thenOK to create it.18.Repeat the filleting operation betweenthe other sweep element and thecentral portion of the part, and enteringa fillet radius of 1mm (make sure thearrows are pointing up).19.Click OK to create the fillet.The created elements are added to the specification tree:20.Using the Historical GraphThis task shows how to use the Historical Graph's commands and contextual commands.Open any .CATPart document.1.Select the element for which you want to displaythe historical graph.2.Click the Show Historical Graph icon. The Historical Graph dialog box appears.In this case, you can examine the history of events that led to the construction of the Multi-sections surface.1 element. Each branch of the graph can be expanded or collapsed depending on the level of detail required. The following icon commands are available:Add Graph Adds a selected element to the graphRemove Graph Removes a selected element from the graphReframe Centers the graph in the windowSurface or Part graph represen tation Gives a horizonta l or vertical represen tationParamet ers Displays any paramet ers associate d with the elements in the graphConstrai nts Displays any constrain ts associate d with the elements in the graph3.Right-click anywhere in the historical graph todisplay the contextual menu:Hide/Show Hides or shows an elementProperties Displays the properties of an elementReframe graph Centers the graph in the windowPrint whole Allows you to obtain a print of the graphGraph All Displays the whole graph of the part (as well as the roots and their first parents)Clean Graph Clears the graph from the windowRefresh Refreshes the graph displayExpand All Displays the parents of the elements in the graph (but not the roots)Selecting andright-clicki ng an element enables the user to add the children to the selected element.4.Transforming the PartThis task shows you how to modify the part byapplying an affinity operation.1.Click the Affinity icon.The Affinity Definition dialog box appears.2.Select the end section profile to betransformed by the affinity.3.Specify the characteristics of the axissystem to be used for the affinity operation:o point PT0 as the origino plane XY as reference plane o X axis as the reference axis.4.Specify the affinity ratios: X=1, Y=1 andZ=1.5.5.Click OK to create the new profile.6.Edit the definition of the multi-sectionssurface (Multi-sections Surface.1), bydouble-clicking it, then select the secondsection, click the Replace button and select the new profile.7.Click OK in the dialog box.8.If needed, click the Update iconto update your design.Multi-selection isavailable.Refer toSelectingUsingMulti-Output to findout how todisplayandmanagethe list ofselectedelements. 9.。
