This dialog converts a curve to a point curve on
surface (page 1–1176)
or CV curve on surface
(page 1–1174)
. The Make C OS button that
displays it is enabled only for the following types
of curves:
•
U iso cur ves (page 1–1170)
• V iso cur ves (page 1–1170)
• Normal projected curves (page 1–1171)
• Vector projected curves (page 1–1172)
• Surface-surface intersection curves (page
1–1167)
• Surface edge curves (p age 1–1178)
• CV curves on surfaces (page 1–1174)
• Point curves on surfaces (page 1–1176)
If the curve is already a curve on sur face, this
dialog lets you change its type.
Inter face
CV Curve on Surfa ce—Converts the curve to a C V
cur ve on surface.
Number of CVs —SpecifiesthenumberofCVsin
the new curve.
Point Cur v e on Su rf a ce—Converts the curve to a
point curve on surface.
Number of Points —Sp ecifies the number of points
in the new curve.
Prev iew—When on, previews the effect of the
conversion in viewports. Default=on.
Convert Surface Dialog
Modify panel > Select NURBS surface sub-object. >
Sur face Common rollout > Convert Surface button
This dialog provides a general way to convert one
kind of a surface to another or to adjust a surface’s
parameters.
Interf ace
Loft tab
If the surface isn’t already a loft, this tab converts it
to the kind of loft you indicate.
The controls are comparable to those in the
Make
Loft dialog (page 1–1235)
.
Fr o m U I s o Li n es—Usescurvesalongthesurface’sU
dimensiontoconstructaUloft.
Fr o m V I so Li n e s —Uses curves along the surface’s
V dimension to construct a U loft. If the surface
was already a U loft, set this to change the lofting
dimension.
