Hi Rajesh!

Kangaroo can be helpful in various cases. Mainly, I believe if you want to have your design follow and adapt to physics based rules. Like forces of gravity, tension, forces between members etc. For instance if you have a pavilion, you could use Kangaroo to find the 'perfect' shape for the forces to go down and thus minimizing individual member sizes. Another method is to relax panels on a surface to have them conform to a set of forces you specify so they maintain similar shapes. I recently made course using a bit of Kangaroo to do this, see here: https://thinkparametric.com/course/panel-clustering-using-machine-learning-soumaya-museum

Good luck!
