I suspect that your curve is free form and not a clearly defined function or a multiple of seperate curves...

So one approach may be to use TNB-Frame to follow the principal curve and create adjacent curves as a function of the primary .

The example that comes to mind uses parametric form for the curve is easy to manipulate.Then new spacecurves allow you to use polygon plot to lay out surfaces. Stick with TNB-Frame and you will have all the ability to examine Tangents Velocity and Acceleration . The archives have some example sheets.You will probably find the frame useful for locating the side rails and then the center rail. I used it to wrap multiple pipes around Tower like structures.

My code is very large and not posted but i have a Sky Drive site for examples.

If you can not find the example sheets i may still have a copy.

Look at this video but unfortunately I think the code is Long Lost in an Accident.

When you wish to build surfaces you will use the ops to extract the points.

But I may have some bits left I will look in my archives.

TNB-Frame with spacecurves

I might have screwed up somehow. But visit my site

And there still exists one remnant worksheet in my archive that should help.

This is new for me, sorry.
