Connect 3-D Curve to 3-D Point
3-D FFS > Via connection > Connect 3-D curve to 3-D point 
Use this function to create a freeform surface by connecting a curve with an individual point.
- Identify the boundary curve.
- Determine the apex via specification of a point.
The resulting freeform surface is a surface of the NURB type.
