The cluster could not be created

I have a problem with creating my cluster I don’t know why… ( it’s the first time that it happens)


Cluster.gh (20.1 KB)

I could imagine its because of the component with the panel which has an output out of the cluster and goes back in

Yup, if the selection isn’t fully ‘convex’, then clusters cannot be created from it.

convex? I don’t undersand what do you mean… :frowning:

Just also insert the component in the bottom left (after the panel, like Baris mentioned already) in the cluster and it should work

But I want this component outside the cluster, because I need to change it in every single re-use :confused:

A selection set in Grasshopper can be either Convex, Concave or Disjoint (ignoring the trivial cases of None and Singular). If a selection contains two objects A and B, and there is a third object C which is a (potentially indirect) recipient of A and a (potentially indirect) source for B then the selection is either concave or disjoint. Only convex selections can be turned into clusters.


Convex: travelling along wires, the only way from any object in the selection to any of its selected recipients is through selected intermediate objects.



Concave: travelling along wires, there is at least one way to travel from an object to one of its selected recipients entirely within the selection and at least one way which exits and then re-enters the selection.



Disjoint: there exists at least one object/recipient pair for which it is not possible to travel between them without leaving the selection.

Still don’t get why the component needs to be outside, all you need is access to the input. You should be declaring cluster input and outputs with the Cluster Input Component and the Cluster Output Component before making the cluster.
