Insert additional edit points or isoparametric curves into a curve or surface

Inserts edit points into a curve, or isoparametric curves into a surface. This results in additional spans/patches and accompanying CVs. Also creates a curve-on-surface at a specific U or V value.

1. Choose Object Edit > Insert ❒.
2. For surfaces, choose in the option box if you want to insert an isoparametric curve or a curve-on surface. Click Go.
3. Click the curve or surface.

   For surfaces, click an isoparametric curve (U or V) in the direction you want to insert.

4. Drag the locator to the position at which you want to insert. You can also type a parameter value in the prompt line.
   Tip:

   Press + (Windows) or + (Mac) and click to snap to a patch edge or curve.

   Press (Windows) or (Mac) and click to snap to the halfway (in parametric distance) points between edit points/isoparametric curves.

5. Click Go.
