Chapter 7 - Feature CreationC HAPTER 7Feature CreationParts are modeled by creating features. Features are individual 3D shapes representingcommon mechanical design elements, like bosses and holes, which either creatematerial or remove material in a part. Many features, such as extrude boss and revolveboss, require an associated sketch to define the 2D profile of the 3D shape. Otherfeatures, such as fillet and edge chamfer, can be created without a sketch and areapplied to existing edges and faces.In This ChapterThe Part Modeling Interface ............................................................ 158Feature Terminology ...................................................................... 159Extrude Boss and Extrude Cut ......................................................... 160Revolve Boss and Revolve Cut......................................................... 165Loft Boss and Loft Cut .................................................................... 168Sweep Boss and Sweep Cut ............................................................ 172Helical Boss and Helical Cut ............................................................ 177Fillet ............................................................................................ 181Chamfers...................................................................................... 184Shells........................................................................................... 186Draft Faces ................................................................................... 187Holes ........................................................................................... 188Catalog Features ........................................................................... 190Copying Existing Features............................................................... 193Design Boolean Features ................................................................ 198Scaling Parts ................................................................................. 201Managing Features in the Design Explorer......................................... 202157
