formZ SDK | 5.0 API Reference | System | Nurbs Surface
Description
Adds a control line to a NURBS surface in the U or V direction after the nth control line. The new control line is added in between the (n)th and (n+1)th lines at a distance interpolated by the specified ratio. For instance, a ratio of 0.5 would add a control line exactly in between the (n)th and (n+1)th lines. A ratio < 0.5 would make a new control line closer to the (n)th line than the (n+1)th line while a ratio > 0.5 would make it closer to the (n+1)th line.
