Procedure
To unlock interior edges:
When you move an outer or boundar y edge of
a patch, the adjacent interior edges are normally
“locked” s o that they move in paral lel with the
boundary edge. This is often useful, because it
provides a uniform transition across the patch.
This default is known as Auto Interior.
•At
Patch level (page 1–971) ,youcanchange
the default on a patch-by-patch basis by
right-clicking a patch and choosing Manual
Interior from the Tools 1 (upper-left) quadrant
of the quad menu. Thereafter, when you move a
boundar y edge, interior edges are affected in a
nonlinear way. The interior edges are no longer
locked to the boundary edge.
Wa rni ng: If you return a patch to the default,
changes caused by Manual Interior are lost.
