Randomly array objects along a curve, but with fixed distances

[Pieter_van_den_broek (Pieter van den broek | MVSA)]

Hey, I’m making a frame in Grasshopper and I want to array the vertical frame along a curve, but the distances between are fixed (200, 600, 800, 1000, 1200) but randomly chosen. How is this possible.

Randomly rotate the rectangle by 0 or 90 degrees

my general approach for this concept of constrained randomness. have a bank of values (eg a list of numbers, 0 and 90 in your case, in a text panel) that you then duplicate many times (~at least twice as many values as you have objects) jitter the duplicated values to get the randomness cull the excess duplicated and jittered values to match the number of objects you have

also, you may find it easier to use PFrame with a range of random points in the curves domain instead of ArrCurve to locate the frames.

Hey, thanks for your solution. I only have a little problem when measuring the distances between the vertical elements, because the don’t correspond to the input distances. Do you know how to solve this?

Is that okay?

Almost, if i bake it and measure it than the measurement from the list aren’t corresponding with the dimension between the vertical elements. I want to place panels of a certain measurement in between the vertical elements. So the distance between the vertical elements should to be the same as the input distances.

I hadn’t taken into consideration the length of the curve which is much greater than the sum of the distances between the elements.
This is exactly how the position of the elements should be.
To fill the entire curve, many more would be needed.
