Adds control vertices in the U or V direction, or adds points directly on a surface or spline. This illustration shows a row of control vertices added in the V direction.
The following prompts are displayed.
Select a valid NURBS surface or curve and press Enter.
Select a valid NURBS surface or curve and press Enter.
Turns off the display of control vertices and allows you to place a point directly on a surface. This option only displays if you select a surface; it does not display for splines.
Turns off the display of control vertices and allows you to place a point directly on a spline. This option only displays if you select a spline; it does not display for surfaces.
Specifies whether to add control vertices in the U or V direction. This option only displays if you select a surface; it does not display for splines.
