Exam 2: Wireframe and Surface Modeling in AutoCad

Solid models are used more frequently than surface models or wireframes because they

An analytic surface is one that

To create a revolved solid, use the

All of the following objects can be extruded except a(n)

The disadvantage of solids created using pure primitive instancing is that

All of the following are surface primitives except the

By default, AutoCAD displays all kinds of models in wireframe format. To find out which type of solid a specific model is, use the

Surface models are used mostly in

To store and display modeling information, AutoCAD uses

Spatial occupancy enumeration is rarely used in CAD applications because it

To control the type of surface created using the Smooth surface option of the PEDIT command, use the

The Spline option of the PEDIT command

The ISOLINES system variable specifies

Surface models are considered to be more advanced than wireframe models because

A surface primitive is a(n)

To avoid surprises when you create a wireframe model, it is a good idea to

Compared with surface and solid models, wireframe models take

The number of segments in a tabulated surface is controlled by the

To create an approximation of a Coons patch in AutoCAD, use the

A fillet surface is used to
