The Surface Approximation utility lets you change approximation and display settings without going into the NURBS model, and is especially useful for changing settings on multiple NURBS objects at once.
It has two rollouts, one for surface approximation and the other for surface display controls:
To use the Surface Approximation utility:
Utilities panel, click the More button, and choose Surface Approximation from the list.
Select the NURBS objects to apply the settings to.
The controls in the Surface Approximation rollout are the same as the surface approximation controls for NURBS surface objects, with two additional buttons: Set Selected and Reset.
The controls in the Surface Display rollout are the same as the display controls for NURBS surface objects, with two additional buttons: Set Selected and Reset.
