1232 Chapter 9: Surface Modeling
Remove Animation—
Removes animation
controllers from the selected texture points.
Reset to Defaults—Resets user-defined mapping
to the default.
Rebuild—Displays the Rebuild Texture Surface
dialog (page 1–1236), which rebuilds the texture
surface and lets you change the number of CV
rows or columns.
Insert R ow, Insert Col., Insert B oth—Click one of
these buttons to insert a row or column of points,
or both at once, in to the surface. Insertion adds
points without moving other rows and columns.
While you refine the surface, the operation is
previewed the same way Inser t is previewed in 3D
viewports.
Delete Row, Delete Col., Delete B oth—Click one of
these buttons to delete a row or column of points,
or both at once.

Inter face
ZIP tab
This tab chooses the zip algorithm. Zipping
concatenates the CV lattices of the two original
curves. Zipping can change the shape of the
original curves, but usual ly it produces a better
result than joining.
By default, the ZIP tab is active.
If both curves are untrimmed point curves, the
result of zipping is a point curve. In all other cases,
the result is a CV curve.
Tolerance—Adistancein3dsMaxunits. Ifthe
ends of the two original curves are closer than this
distance, zipping deletes one of the points or CVs
in order to avoid creating coincident points or CVs
in the new zipped curve.

Tension 2—(Disabled.)
Join tab
This tab chooses the join algorithm. Joining first
creates a blend curve between the two original
curves, a nd then makes all three i nto a single
cur ve. Joining does not change the shape of the
two original curves.
If b oth curves are point curves, the result is a point
curve. If one or both curves are CV curves, the
result is a CV curve.

than this value, the join is c reated by first creating
a blend curve and then joining the three parts. If
the gap is less than this value, or if the curves are
overlapping or coincident, the software doesn’t
create the blend.
Creating a blend and then joining the three curves
into a single curve is the better technique. The
result matches the parent curves well. Without the
