[image] The objective is to pack as tight as possible, and randomly the irregular curves into the rectangle shape, without using OpenNest as the algorithm leaves many gaps, and sorts the shapes from largest to smallest, which we don’t want. No overlapping with the rectangle or each other. curves…

Hi, One possible way to do that could be the classic and simple bottom left to top algorithm. import Rhino import scriptcontext import rhinoscriptsyntax as rs def NestingAlgorithmBFD(): rectangle_id = rs.GetObject("Select a rectangle", rs.filter.curve) if rectangle_id is None: ret…

When running this through opennest, it sorts from largest to smallest, which is not randomized.

Maybe this change help you: import random import rhinoscriptsyntax as rs def NestingAlgorithmRandom(): rectangle_id = rs.GetObject("Select a rectangle", rs.filter.curve) if rectangle_id is None: return rectangle_curve = rs.coercecurve(rectangle_id) curves_ids = rs.Ge…

As you put this in the Kangaroo section, I’m guessing you’re after something like this [image] curves into rectangle.gh (37.2 KB) CurveCollide accepts passive curves for the active ones to collide with, but note that these are always taken as exterior boundaries (we can’t make a rectangular hole…

I tried to adapt one of your definitions earlier today but couldn’t do it.

Here’s your solution from above with an automated slider:
