Hi, I already submitted this post some time ago and eventually ended up with a pretty interesting result modifying an already scripted version. See links [image] Balloon restricted by strings Grasshopper Hi, I have been interested in creating a balloon like geometry whi…

Here’s an example which is quite close to my scan above: [image] Note the base brep is a revolved section of the ballon which is split into 4 pieces and then joined again. It is split so the mesh later on has vertices exactly on the symmetry planes. Without vertices and edges along the symmetry p…

But to clarify my concern it not necessarily factually proven, but only from what I can see looking at the model. In the 3D print aswell as the GH/RH model th…

[image] Ester: an inherited factor That is just a mesh un-welded edge. Weld your mesh. Then run “RebuildMeshNormals” command. Or… you can just use the “Combine&Clean” component (from kangaroo tab) on your mesh, which will have the same result. Anyway, yes, I think it’s impossible to have a …

By the way, I was wrong about the mesh sphere ex! It indeed has some naked edges, which it shouldn’t. This might be an issue with the component? Here’s how you can build something similar from scratch that is watertight: [Screenshot 2022-02-19 at 10.19.18] You’re also right that a triangulated m…

Which Rhino version are you using? That error looks related to a bug which was fixed a while ago, so updating to a current service release should fix it.

Thanks for the advice, I downloaded the newest rhino but still have the same errors unfortunately e

Did you change a parameter or delete any of the input geometries? [image]

This one is ceramic, but the real one is about 10’ tall and made (somehow) from 1/2’ steel plate. It looked like magic to me, but I guess he knows how to do that.
