How to simulate Relaxed Roman Shade curtain, fixed along perimeter

[michaelvollrath]

Hi @blakeaitken02 ,

Take a look at this post where Daniel shares a horizontal drawn curtain script.

How can I create a simulations of a curtain? Grasshopper

Here’s a version for the curved rail that moves all the attached points along the rail simultaneously curtain_rail2.gh (21.4 KB)

If you extrapolate the logic to have the points start at the bottom and pull up on the Z instead of the example shown with a horizontal approach I believe you will get a close result to what you seek.

Hope that helps!
