Answers to the Joystick
Tutorial quiz
- (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.
- 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.
- 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.
- 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.
- d) The Transform > Local
> Center Pivot tool. This tool can be used with all
objects, curves, surfaces, and groups of CVs.
