No, for planar surfaces it is normally best to use Planar and get a simple plane that is trimmed like you did already.

Network has the requirement that you have to give it a regular criss-crossing grid of curves, you can't just grab any set of random curves and use Network on them, they have to have a grid pattern which can be bending or compressed in different areas, but still needs to have the same kind of grid thing as longitude and latitude lines on a map. Basically there has to be a rectangular pattern to the curves to be networked.
