# 2- Wavy Facade 2

In this Paracourse lesson, we are going to model a wavy facade in Grasshopper. First, we are going to model the strips and then by using the curve attractor technique and some data management tricks we will model the louvers.

1.jpgHi there! I have a question on making wavy facade on a looped surface (like the attached image) instead of a plane surface.

Since the attractor attracts all points at one direction (say either x or y-axis), how can I define the closest points go to the closest points??

Thank you!

Hi Angie

Please watch this tutorial for more info

For the distance, you can use the Geodesic component to find the shortest path on the surface and use the curve’s length for your rotation but be aware it’s a slow process
