ACIS is a solid modeler that can combine wireframe, surface, and solid models. A wireframe model defines an object only by its edges and vertices. A surface model is similar to a wireframe model, but defines an object by its visible surfaces, including faces. A solid model defines an object in terms of its size, shape, density, and physical properties (weight, volume, center of gravity, etc.).
In the preceding sections, only the functionality of wireframe and surface models were exercised. In this section, solid models are explored. ACIS provides a variety of ways to create solids. The examples in this chapter create solids by:
	Using solid primitives
	Enclosing a void
	Sweeping a surface
