Can someone help me out with this?

I need a surface area profile (x,y plot) of a simple loft as I move along the axis of the loft. In other words, the surface area profile
would start out at zero, and at the end of the x axis, it would equal
the entire surface area of the loft (without the start and stop
shapes). Note that I am after the surface area of the loft as I sweep
through the loft, not the cross-sectional area of the loft.

I can do it manually by sweeping a section view through the loft and using measure at each step, but this would take FOREVER to do.

If this is too hard, can I do the same with the cross section perimeter as a function of x?

Thanks much in advance
