I've been repairing some surfacing models, and I end up in situations where a filled surface, boundary surface, and lofted surface would probably all work equally well.

Are there situations where one feature is more desirable than the others?

Does one affect performance more than the others?

The one I understand the least is boundary surface. What makes this different from a lofted surface?

Sorry I'm not more specific, I'm just kind of looking for rough general guidelines.
