It looks like a design patent application can satisfy both enablement and definiteness with a single drawing.

I know, you were on the edge of your seat about this one. Yet, it is a significant case for what is sufficient for a design application. In In Re Maatita, The Federal Circuit found: “[T]he fact that shoe bottoms can have three-dimensional aspects does not change the fact that their ornamental design is capable of being disclosed and judged from a two-dimensional plan- or planar-view perspective – and that Maatita’s two-dimensional drawing clearly demonstrates the perspective from which the shoe bottom should be viewed.”

Some interesting commentary can be found here.
