Triple taper solids

[ohiocad]

I'm hoping someone can help. I've tried without success to creat a tapered solid, using AutoCAD 2000. It is supposed to end up looking almost like an ellipse, that tapers in length, and height as it is extruded, almost like an airplane wing, with a varying ratio between the height/width. (i.e. starts at 12 long and 3 tall, and ends at 4 long and 2 tall, and the back edge tapers forward twice as far as the front tapers back) Any hints?

I've tried to create the geometry you describe without having any luck myself. It is relatively easy to create a surface model, as opposed to a solid model, of your geometry. Will a surface model suffice?
