Doing something very difficult

Hi there,

Although I am new I am trying to do some incredibly complicated stuff for uni. 

I have a vertical surface which is a lofted rotated tower and I want to create ribs for it so that I can laser cut it.i.e.

So I have vertical and horizontal elements to my model, to basically create a mesh.

I have this definition from our tutor but have no idea how I would adjust it to make it work for such a complex geometry.

see attached definition and screen shot of geometry

Any ideas

Regards

Stuart
