Grasshopper Alternative to RailClone for Automatic Pattern Generation

Hi everyone,

I’m looking for a way to replicate in Grasshopper the functionality of RailClone (I’ll link a video for reference). The key feature I’m interested in is the ability to select polylines or surfaces along with a modular geometry, and automatically generate a repeating pattern that adapts to the selected input.

A particularly useful aspect of RailClone is how it handles irregular surfaces —even if a surface is trimmed or non-rectangular, the generated pattern automatically clips and adjusts to fit perfectly within the surface boundaries.

Is there a way to achieve this in Grasshopper?

Thanks in advance.
