CV surface sub-objects are similar to object-level
CV surfaces (page 1–1105) .

Procedure
To create a CV surface sub-object:
1.
InaNURBSobject,turnonCVSurf
ontheCreateSurfacesrolloutorCreateCV
Surface in the toolbox.
2. In a viewport, drag to specify the initial area
of the CV surface.
3. Adjust the CV surface’s creation parameters.
Interf ace
The p ar ameters that appear when you create a CV
surface sub-object differ from those you see when
you modify it as a sub-object.
