3 CURVE allows you to create a spline mesh that is defined
by either two generator curves and a director curve, or by
one generator curve and two director curves. The mesh
approximates the blending of the two, two-curve surfaces.

Define the sweep of the profile by choosing from the
following options:


TRANSL   (translate) - to maintain the generator curve's
         orientation relative to the world coordinate 
         frame as the generator curve is moved along 
         the director curve.

ROTATE - to maintain the generator curve's orientation to 
         the director curve as the generator curve is 
         moved along the director curve.


Select the line, arc, conic, or spline to be used as the
first generator curve.

Select the line, arc, conic, or spline to be used as the
second generator curve (if you want to select two director
curves rather than two generator curves, press <Enter>).

Enter the number of segments that the generator curve(s) 
are to be broken into.

If you are using two generator curves, select the line, 
arc, conic, or spline to be used as a director curve. If 
you are using one generator curve, select the two lines,
arcs, conics, or splines to be used as the two director
curves.

Enter the number of segments that the director curve(s) 
are to be broken into.

A temporary mesh is displayed, along with a NO/YES menu. 
If the curves are connected correctly, choose YES. If the
curves are not connected correctly, choose NO and select
another generator curve.

Indicate whether to group the entities. Choose NO to
continue without grouping. Choose YES to create a group,
and enter a group name.

The mesh is created.
