Chapter 7 - Feature CreationC HAPTER 7Feature CreationParts are modeled by creating features. Features are individual 3D shapes representing commonmechanical design elements, like bosses and holes, which either create material or remove materialin a part. Many features, such as extrude boss and revolve boss, require an associated sketch todefine the 2D profile of the 3D shape. Other features, such as fillet and edge chamfer, can becreated without a sketch and are applied to existing edges and faces.In This ChapterThe Part Modeling Interface .................................................................................... 148Feature Terminology ............................................................................................... 149Extrude Boss and Extrude Cut ................................................................................ 150Revolve Boss and Revolve Cut ............................................................................... 155Loft Boss and Loft Cut ............................................................................................. 158Sweep Boss and Sweep Cut ................................................................................... 162Helical Boss and Helical Cut ................................................................................... 166Fillet ......................................................................................................................... 169Chamfers ................................................................................................................. 172Shells....................................................................................................................... 174Draft Faces .............................................................................................................. 175Holes ....................................................................................................................... 176Catalog Features ..................................................................................................... 178Copying Existing Features....................................................................................... 180Design Boolean Features ........................................................................................ 184Scaling Parts ........................................................................................................... 187Managing Features in the Design Explorer ............................................................. 188147
