Need help Generating Stairs on a Non-Planar Surface in Grasshopper

[Joseph_Oster]

This thread reminds me of another one four years ago, long and complex with parametric landings, max steps between landings, etc. I don’t recall it going up and down though.

Generative staircases on terrain

This one is not too shabby! The path is projected onto the terrain surface and contoured, then projected to the ‘World XY’ plane along with the contour points. The Anemone loop proceeds through the points and starts a new flight of steps when the horizontal distance from start point to current point is greater than the sum of (numSteps * ‘going’ (tread “length”)) + ‘Landing (minimum)’. I don’t bother counting steps to force breaking a flight. There is one flight of 23 steps at the steepest p…
