sketch fill pattern

[multicaduser]

I'm looking to:

1. create a sketch on a flat face of undetermined shape and size
2. face may or may not contain one or more holes (openings)
3. create a boundary with said face edges
4. fill boundary with a pattern of curves that stay within
5. use sketch to create 3d geometry as a representation of needed feature

Since the face is flat a 3d geometry pattern can be created externally as a feature and applied to the face using a sketch to trim/limit the pattern scope but I'm looking for something a little more self contained. Has anyone done this or something like it?

Update, decided to use pattern feature with a linear definition and a boundary using a face to control the feature. This makes the most flexible and stable feature for a shape which can change dramatically.
