Can’t wait for attributes to be supported in SketchUp!
But here, I’m not talking about a standard attribute belonging to a dictionary, but Sketchup layers/tags!
In Sketchup the structure of a Live Component is hidden and you cannot assign a layer/tag to the sub-entities of the component. Except by detaching the definition Live!
It must therefore be possible to do this from the graph via a “Layer/Tag” node.
