Create a rail curve using "conic" rectangle from center
Create a profile curve (vertical to Cplane) using "conic" rectangle from center
Use "Rail Revolve" to develop the basic surface which will become the spoon
Create a control cage for the surface. Use bounding box option is easiest.Here i set my control cage parameters to be X=7, Y=4, Z=2.
Manipulate the control cage points with basic transformations. I only needed to use Move, Scale1D, Rotate, and Rotate3D to get the points were I needed them.

Hi, I don't understand how you get the nice clean soft surface from just a sweep one rail. I tried it and my surface get all twisted.
I know how to get this surface using 3-4 steps but I want to know how you do it in one single step.
Can you elaborate the first step?
