Into the world of Kangaroo.......

I've been learning the basics of Kangaroo recently. I revisited my uni project in which vaults were created in Grasshopper by lofting a number of catenary curves. I have watched a few helpful tutorials and have created a vault like form using a basic set up,  involving springs, anchor points and a force in the Z direction. In principle it is similar to physically hanging chains, but with the force being applied upwards in the z axis.
