Hi Burr, even if another app automatically applies shrinking (which if it's important to you maybe you can ask them to have a setting to turn it off), that will only affect the outer boundary. Any interior holes of the surface will always have the full underlying surface under them since shrinking only goes down to the outer boundary.

Also the outer boundary will only get shrunk down to an isoparm cut, something like a saw tooth cut like my example above will still be restorable to an even non-sawtooth boundary edge even if shrinking has been applied.

So anyway, even if shrinking is applied it does not totally negate the ability to recover areas of the surface.
