These tutorials explore solid modeling by: Material ♦Extruding ♦Revolving ♦Sweeping A number of additional parametric, feature-based modeling possibilities and formulations are demonstrated in this chapter. Copyrighted 1-2 INTRODUCTION Solid modeling can be accomplished in a number of ways, and one favorite method Material involves starting with a two-dimensional shape and manipulating it to create a solid. That is the approach we will use for many of the object models created in this book. Figure 1-1 shows an L-shaped cross section that has been variously extruded, revolved, or swept along a curve to produce the solid object models shown.
