Non-Uniform Scale - "ease-in" or "ease-out"

Does anyone know of a way to apply something like an "ease-in" or "ease-out" function to a scale in a single direction. I've already tired X-forming certain poles of a surface into the desired height, but continue to have a uniform result when using global shape by surface.

Try Global Shaping. Simplist methof would be "by surface" and use the edit poles option.

Thanks Steven,

 

The Global Shape by surface by using the single base surface and edit poles does offer a good solution.  I am trying to tak it to the next stage where as % of change to the poles differs based on the size.

 

Is there a way to parametrically control the base surface with the same percent of change to the poles between largest to smallest size.

you could try gobal shaoing using difference between two surfaces with the surfaces being constructed from sketches. It will probalby not be precise but at least close to predictability of most processes and controlable.

In the first post you say "scale in a single direction".
NX has a scale feature which can scale in a single axis, is this not what you look for ?
Search for Scale body then set type to General.
