Study of Fiera di Milano's node using Generative Components

I begin to describe the node:

on the pictures we can see that consist of two disk shaped elements where are four principal beam and two other secondary, the angles between those are variable.

 I tried to create this node with GC:

the first thing is to place a point, the center of the node, and then to create 2 circles

the model has six global variables wich describes the beam's positions, the radius of the node and the space between the two disks.

we can change the values of the node.
