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.
