Inter face
Tolerance—Rebuilds the surface according to
accurac y. T he lower the Tolerance value, the more
accurate the rebuild. Increasing Tolerance enables
the surface to b e rebuilt using fewer CVs .
Number—(The default.) Lets you alter the number
of CVs in t he surface. Number in U specifies the
number in the U dimension, and Number in V
specifies the number in the V dimension. These
values default to the numbers that already exist in
the surface.
Prev iew—When on (the default), your changes are
previewed in viewports.

This dialog rebuilds the texture sur face and lets
you change the number of CV rows or columns.

Number i n U—Sets the number of CV columns.
Number i n V —Sets the number of C V rows.

button
The Reparam. button for CV cur ves and surfaces
displays this dialog. Reparameterizing a CV
sub-object changes its
parameter space (page
3–1082)
to provide a better relation between
control point locations and the shape of the
sub-object.
Tip: It is a good idea to reparameterize after you
have added CVs to a curve or surface by refining
or inserting.
