How to get a model Nested Component(group) tree Information

[Nick_G]

From a selected element, you can get the definition of a component instance, and then get that component’s entities. You can then enumerate that to find child components.

@ChrisDizon

model = Sketchup.active_model
ss = model.selection

find the definition of the component instance ss[0]. ss[0] is the 1st selection in the selection set
definition = ss[0].definition

#Get the entities within the component definition.
internal_ents = definition.entities
