I am trying to write a Grasshopper script for Stairs made out of two curves. I loft the 2 curves then divide the curves and use the points to get lines which split the surface. After that i want to move the single surfaces with a series along the Z vector. But somehow the order of the Surfaces got messed up after the Surface Split so the series doesn’t work well. I tried a lot of shifting and culling but couldn’t get a good result - Would be realy nice if you guys could help me fixing the order
I have done it like that befor and it works well for a lot of different stairs but when you got a inner circle sourrended by a square both are divided in equal length with the konsequent that the stairs aren’t perpendicular to the circle - thats why i want to use lines to divide.
For the lines which divide to loft i used offset and and closest point to get those perpendicular lines on the loft.
Johannespetersen7,
So I approached it a little differently. Because the lines are in order, I picked line index 0 and index 1, then index 1 and index 2 etc. I then used those pairs to loft a surface which you can then move in the Z directions as needed. Not the cleanest solution, however it appears to work. Hope this helps.

That works well for this particular situation but it would be nice to have a more general solution. I could probably creat such a solution with more operation for curves…
Do you guys know a plugin with more curve operation beside pufferfish?
