How to make a gradient scale in Grasshopper?

[sweezy_AFK]

Hi everyone,

I’m trying to create a gradient scale effect in Grasshopper. I already have the base geometry (rotation, extrusion, etc.), but I need to scale it so that the bottom is larger and it gradually decreases (or increases) towards the top.

I tried using sine/π functions to control the scaling, but it feels too complicated. Is there a simpler way to achieve a smooth gradient scaling of curves or geometry (for example, from factor 2 at the bottom to 1 at the top)?

Thanks in advance!
