Parametric Rectangular Ramp

Hi,

I'd like to create a parametric rectangular ramp where the ramp gradually moves up like a cake(or like the Empire State Building). So, the bottom will be wider than the top.

I have been trying to use the definitions of a spiral ramp that I found here, but having a hard time because of my lack of knowledge of grasshopper. I only know very basic stuff. I managed to create a multiple floor using divide? division? But I got lost trying to combine it with the spiral ramp definitions.

Thank you very much and I hope that you can help me with this.

Hi Ann,

I am afraid your explanation is not very clear...

Could you post a sketch of what you are trying to do?

Hi Nikos,

Thank you very much for trying to help me with this.

Attached is the sketch. Basically it's just a basic rectangle ramp, but I want it to be parametric that the ramp gradually gets smaller in size as it gets higher.

Hi,

A friend tried to help, but we couldn't get the cull pattern right. We know that it would be easy to loft the surface once the pattern is right.

Thanks,

Ann

I gave it a try.

It came out too complicated (I bet there is a much faster way to do this) but it works:

You can control the overall size of the ramp, start and end width, elevation between steps and total number of turns.

Hope this works for you!

Cheers, Nikos

Hi Nikos,

Thank you very much for the help. You have been such a blessing for me.

I have a question though, why does the definition only works with square? I thought that if I add another number slider, I can play with the rectangle. Is it hard if I want the shape to also be parametric?
