What determines whether a group of objects can be clustered or not?

I have a very large definition which is stable and I’d like to start using clusters to clean up the canvas and hopefully reduce the frequency of Grasshopper throwing up drawing errors from too many components.

I’d like to be able to cluster large groups of component groups together under one topic, but I’m having a hard time understanding why the cluster command is available when I have some selections chosen, but on others the cluster command is greyed out.

Is there any reference documentation for the cluster command? Google searches have not been helpful so far.

The selection set has to be convex. Meaning it may not be the case that a selected object has a source which is itself unselected but which in turn has another source which is selected again.

Aha that makes sense.

Thanks David!
