Select all your surfaces.

Go to Window > General Editors > Attribute Spreadsheet.

Click on the Tesselation tab.

Turn on "Explicit Tesselation" for all your nurbs surfaces. You may also want to turn all your surface's curvature tolerance to High Quality and if you scroll to the right, turn "Use Chord Hieght Ratio" off.

Experiment with some of these tessellation settings to get the result you want. The Attribute Spread Sheet lets you make changes to all your patches at once.
