Turns a surface into a bleacher

Hi, i know almost nothing about grasshopper and rhino, but i have this feeling that this project could easelly be done with these programs. I have these half elipitical(?) surfaces which i want to transform into a huge bleacher. about 10 (?) curves must have 0.50cm of high and as it goes to the top i want them to softly decrease of high. it is important that the curves always leave from the ellipse, so that when the project is viewed from the front, the ladder does not appear. i dont know with you guys will understand, i have this bad english, but i'll leave here some photos of my project and one photo of the bleacher made by jaja architects. i wanna do the same, but applied to my volume.

Sounds like you could use the Contour component to slice your pre-existing surfaces at the desired elevations, then operate on the resulting curves. Maybe an offset and extrude is enough to create your shapes?

i'm pretty sure i have no idea about what i'm doing hahaha
please, could you help me? maybe do you have some archive that fits my need?

1. how can i do to make the 10 firts curves with 0.50cm of high and make the rest softly decrease?
2. also, for exemplo, make the 10 first steps with width of 1m to 0.50cm and also the rest softly decrease?

i hope you really understand my logic. this is a project with deadline. i'm really desperate ))):
