Thicken surface by varying amount

[sdar79]

I am modeling a wing skin which has the outer surface defined by loft data that I have a surface model for in NX. Some areas of the skin have a tapered thickness, ie, tapering linearly from say .180 thick at one point to .120 thick further outboard. What's the best way to model this? I am trying to use the "thicken" command and see that I can set the offset value to be the output of a formula. Can this formula include say an "x" coordinate, from which I could write an equation to vary the thickness based on the x value at that location in the model? If so, how can I do this?

Could You show a picture about the surface?

Thank you very much. The "variable offset" in your file is the tool I was looking for, but I did not know I had to enable it to show in the menus. I found it using the command finder.
