Inter face
From U Iso Lines—Usescurvesalongthesurface’sU
dimension to construct a U loft.
Fr o m V I so Line 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.
From U a nd V Iso L ines—Uses curves from both the
UandVdimensionstoconstructaUVloft.
UCurves—Sets the number of curves in U.
VCurves—Sets the number of curves in V.
Use Point Curv es—When on, constructs the loft
from point curves instead of the default CV curves.
Default=off.
Ex tra Points per Segment—This control is enabled
only for UV lofts (From U and V Iso Lines). Lets
you increase the number of points in each segment.
Fuse P oi nt s—This control is enabled only for UV
lofts (From U and V Iso Lines). When on, fuses
points at curve intersections to ensure that the
U and V curves continue to intersect when you
edit the surface, and that the surface remains
coincident with its parent curves. UV lofts
constructed f rom intersecting curves behave more
predictably. Default=on.
Delete Original Loft Curves—This is available only if
the surface was already a U loft or UV loft. When
on, Make Loft deletes the original loft curves when
you click OK. When off, the orig ina l cur ves remain
where they are. Default=off.
Prev iew—When on, displays a preview of the new
loft surface. Loft creat ion is faster w hen Preview
is off. Default=off.
Mak e Point Dialog
Modify panel > Select NURBS surface sub-object. >
Sur face Common rollout > Make Point button
This dialog converts a CV surface sub-object to a
point surface sub-object.
Interf ace
Number i n U—Sets the number of columns.
Number in V—Sets the number of rows.
Prev iew—When on, your changes are previewed in
viewports. Point surface conversion is faster when
Preview is off. Default=off.
