Hi Adam,

I was wondering if you could help me by telling me what component you have used to control the points at the top of your 'structure' please?

Thanks.

I think what you are talking about is a combination of the Evaluate Surface componenten in combination with a MD-Slider (set to 0.5, 0.5, 0). Afterwards move that point in any direction you like (In my case in the direction of the Normal-Vector produced by the Evaluate Surface component) .... I guess its kind of complicated to explain it in writing so here is part of my GH script.

Hope it helps

Thanks for the GH script and the explanation Adam.
