Condition
You see an error on the subdivision feature, or some sort of unexpected bump, ripple, or a
shadow on the surface.

Cause
The control cage might be intersecting itself.

Solution
-
Turn on the control cage by selecting Show cage only in the
subdivision toolbar.
-
Inspect the cage to ensure that the elements are not intersecting. If they are,
move the vertices in that area until the cage is no longer intersecting itself.
