As with splines, if you click over the curve’s
initial point, a Close Curve dialog (page 1–1235)
is displayed. This dialog asks whether you
want the curve to be closed. Click No to keep
the curve open or Yes to close the curve. (You

initial point is displayed as a green circle, and a
green tick mark indicates the curve’s direction.

Rendering rollout
Lets you turn on and off the renderabilit y of the
curve, specify its thickness in the rendered scene,
and apply mapping coordinates.
Render parameters can be animated. For example,
you can animate the number of s ides.
