b. / Material Manager / d. / Primitive palette

____ 10.

The upper figure shows ______.

a. / hyper Object / c. / Loft object
b. / Bezier Object / d. / Lathe Object

____ 11. In the bellow figures, top and bottom figures represent the______.

a. / (Top) Object Coordinate
System; (Bottom) World Coordinate System
b. / (Top) World Coordinate System
System; (Bottom)Object Coordinate

____ 12. To move the spline along only the X axis, choose the ______.

a. / World Coordinate System / c. / Object Coordinate System
b. / Move Tool / d. / Scale Tool

____ 13.

In order to create the above shape you need______.

a. / Hyper NURBS / c. / Sweep NURBS
b. / Bezier NURBS / d. / Extrude NURBS

____ 14.

Rounded blub can be adjusted by using______.

a. / Hyper NURBS / c. / Bezier NURBS
b. / Lathe NURBS / d. / Sweep NURBS

____ 15.

You can create Stage Curtains shape by using______.

a. / Hyper NURBS / c. / Bezier NURBS
b. / Lathe NURBS / d. / Sweep NURBS

____ 16. To play animation press______

a. / F1 / c. / F4
b. / F3 / d. / F8

Matching

a. / Hyper NURBS / d. / Loft NURBS
b. / Extrude NURBS / e. / Sweep NURBS
c. / Lathe NURBS / f. / Bezier NURBS

F____ 17. Is a surface defined by x and y curves with control points. This is the only NURBS tool that requires no child objects.

E____ 18. Moves a profile spline along the path of another spline, the profile may be scaled as it moves along the path, and the path may be animated to grow.

D____ 19. Stretches a surface over profile splines or ribs. A single spline will create a flat object, while any number of multiple ribs will create 3D surfaces that change according to their profiles.

C____ 20. Revolves a profile spline in a rotation around the Y axis to create surface.

B____ 21. Extends a shape as an extrusion, using a 2D object to create a 3D object.

A____ 22. Rounds off an object placed inside it into a more curvilinear, organic version of the geometric original.
