Tangent adds
new isoparms to the extended surface.
Extrapolate rebuilds the surface
according to the direction and distance specified, but without adding
new isoparms.
Distance
Sets
the length of extension.
Extend Side
Specifies
the sides that will be extended; the start is the U0 and V0 location
on the surface. This option is available in the Channel
Box after you extend the surface. Select the extendSurfacen
node to display the option.
Extend Direction
Specifies
the U, V, or U and V directions for the extension to be built. This
option is available in the Channel Box after
you extend the surface. Select the extendSurfacen node to display
the option.
Join to Original
You
can turn off this option only when the Extend Side and Extend
Direction options are not set to Both. Maya disables
the selection of Both for Extend
Side and Direction, and causes Extend
Surfaces to create an unattached and separate surface.
Keep Original
This
option causes Extend Surfaces to keep the original
surface when it builds the new one. Turn this off if you prefer
to discard the original surface.
