To move CV normals

1. In the Tool Palette, select Transform > Modify > Move CV Normal or click the Move CV Normal icon. The system prompts you to select surface CVs.
2. Click a CV to select it. To select several CVs, hold down the Shift key as well. You can also click a hull line to select an entire row of CVs at once. The system prompts you to use the mouse buttons to move CVs.
   
3. You can drag the active CVs using the mouse:
   • left mouse button drags along the normal and back again
   • middle mouse button drags along a U curve of the surface (the height of the CV above the surface is maintained)
   • right mouse button drags along a V curve of the surface (the height of the CV above the surface is maintained)

   You can type values for CV displacements in the N (normal), U, and V directions (in ABS or REL mode).
