Complex triangulated tower (Problem making surfaces)

Hello,

A classmate and I have recently be affected to an assignment of a parametric structure design.

Our choice was to modelise a tower wich is defined by an ellipse that rotates and scales itself depending on the floor level.

Concerning the structure, it is not based on a curved surface but a triangulated one. Each ellipse is segmented in 10 points that will be connected to the next 10 points of the next level. We have modelise theese connections by polylines that links theese points together.

Our problem is that we don't manage to create a surface (or mesh ?) from this simple closed polyline wich could be represented like that : /\/\/\/\/\/\/\/\/\/\

Attached you will find our grasshopper file, if somebody has a minute to look at it and find a solution it will be perfect.

In the file two solutions on the right :

-1up that generates the whol structure of the tower

-1down that generates 3 polylines for a single floor (more interesting for us and the post production, unfolding surface and model creation)

Thank you for your time and patience !

Rémi

Hey,

Actually we are trying to change the ellipses in segments ( 10 per floor ) because we will make a model with a laser cut.
The problem was to connect each floor by a triangulation ( floor by floor because of the construction phase ). We managed to have this triangulation by floor (may be not with the most simple way ) but the problem is to make each triangle becoming a surface because after the printing with the laser cut, we are going to glue each floor together with little strips.

How can we get a surface from each level trianguated by our parameters ( parameters have to be conserved ) ?

I have joined a picture which show you the result we are trying to have.

By the way thank you very much for your time ( your way seems to be simpler than our )

Hello again,

here you have it. It's a bit sloppy and it has some problems. When the "etages" is an odd number it doesn't work right. Also the last step I just copied all the components four times instead of merging because it also didn't work right. I bet you can work out the quirks.

Hey !
Thank you very much this is what we were looking for !
Now we have to understand how you managed to have it and work out the quirks.
Thank you again
