Hi Warren,

It kind of depends on the particular circumstance. But it can make things easier for filleting if you have larger pieces because a single large non-segmented curve or large surface piece will be all smooth inside of it. So that can tend to avoid ending up with things meeting up at some slight shallow angle.

Slight shallow angles between pieces will tend to cause problems with filleting.
