New to Grasshopper/Rhino need design advice

Hi All,

Looking for advice on how to perform something of the sort seen below. It involves an array of a member with variables in (a) + (b) that consecutively compound through (y) - so that the position of the fold increases in height through a revolution.

I work a lot in Revit but thought this a good opportunity to start learning a very interesting program. The least I am after is some vocabulary/terms to start researching where to start with a process like this. This is one study of many further complicated examples I need to develop.

i am sure there are easier ways to do it especially with some math, but this is the first thing came to my mind, manually

its a bit messy, but it works

u can see that from the helical curve

Wow! Thanks Mohamed for the reply, conceptually that's what I'm after. Not sure if I understand the document though. Is there a way of doing it with a 'polar array' and changing the definition (x,y,z) of the control point at the fold / your helical curve?

Having familiarized myself with the definition I have added an extrusion of the surface. Having trouble getting a perpendicular extrusion. Expecting the driving definition (x,y,z) should be replaced with (u,v).

Not quite sure how to define this however, help please.
