Hello everyone,  
would like to ask some help achieving the following

 ![Idea](https://global.discourse-cdn.com/mcneel/uploads/default/original/3X/5/0/50a2a69c8f4142c6b0519bec3d2db313b9388138.jpeg) ![Code](https://global.discourse-cdn.com/mcneel/uploads/default/original/3X/8/9/894248ad32cc8d2f3ee09ec2a9fc2d40d71e4a2b.png)  
I thought to use If then else statment to filter objects with same X coordinate, but this doesnt seem to work. Any ideas would be very much appreciated  
thanks in advance

One of many options is to create set from flattened pool of points (x-coordinate) and then branch them per same x. Later you just need to sort them on fitted circle for example and join them via polyline.

Thanks Jakinta,  
could you be a bit more specific? I am relatively new to grasshoper (not to programing though) i am not yet so familiar with its data structures. Trees and branches are kind of novelty for me.
