I've been trying to recall this tip for several months nowand owe a handful of people some info on it. I finally asked theright people so I'm putting it out here for posterity...

The Split Line feature only allows face splitting with a singleclosed curve. This can be extremely frustrating if you want tosplit with a pattern of closed curves.

An alternate technique is the use the Insert > Feature > Wrapwith the "Scribe" option. This allows a sketch with many closed,non-intersecting curves to split a face.

Hope you find this useful!!
