3 Features, equations, lights, views, physical properties

4 Feature-Based Solid Modeling Parts modeled by adding features to a base part Material can be added or subtracted Features can be created by extrusion, sweeping, revolving, etc.

5 Feature-based Modeling Process Create base part Add features until final shape is achieved Extruded BaseExtruded Cut

6 Extrusion Sweep Hole Revolution Loft Extruded cut Sample of features
