I would like to achieve the following intersection between 3 pipes:
The final goal is to then extrude the centre triangle face outwards, and apply a subdivision modifier to get a smooth spike shape:
My question is: How do I create such a Y-shaped intersection with an ico sphere and geometry nodes?
So far, I've created an ico sphere and applied a square curve profile along the edges. Next, I would like to somehow merge the intersecting profiles to create the desired intersections shown in the image above, but I have no idea how to do so.
