Answers to the Joystick Tutorial quiz

1. (d) Four CVs. You created a default degree 3 curve, which requires a minimum of 4 CVs before it is created. To learn more about CVs and curve degree, see Mathematical representations of curves.
2. c) Two or more curves can be used to build a skin surface. If only two curves are used, a ruled, straight, surface is created between them. If more curves are used, use the shift key to select the third and subsequent curves. The surface is blended smoothly through all the curves.
3. c) The Pick > Hull tool. A whole row of CVs can also be selected using Pick > CV and carefully dragging a pick box around the required CVs. The Pick > Hull tool is often easier to use, and it is often good practice to modify a whole row of CVs together, to have more control over the final shape of a surface.
4. e) All of the options listed can be displayed using the Hardware Shade tool. This tool has been significantly enhanced in Alias and can be used very effectively to present and visualize your designs.
5. d) The Transform > Local > Center Pivot tool. This tool can be used with all objects, curves, surfaces, and groups of CVs.
