Hello,
I am currently struggling with designing shells in Kangaroo. I have the basic form and some grasp of using Kangaroo, but i would like to stretch the mesh out to planar arches, as seen in the picture below which is a top view:
The shape of the arch is of course only known after running the Kangaroo solver in the first place. Is it possible to lock the naked mesh vertices along some arbitrary axis, so that it doesn’t collapse inward?
Another view:
Many thanks in advance.

You can use the anchor goal if you know the target position of the naked vertices. If not, there’s the OnCurve goal.
Thank you very much, OnCurve works like a charm
Bear in mind that this constrained shape is no longer a true catenary. The vault will now be partly supported by ““false” foundations along each arc. The arch in plan is there to transmit horizontal forces into the true foundations. By making the edges straight, it’s like you’ve swapped arches for unsupported beams in a load bearing wall. If you built it, you’d find the edges would fall outwards and the vault would collapse.
