Ok I understand, thank you. I have just been reading about objects (a collection of raw geometry) vs components vs groups. And I have discovered Outliner
Two further questions if I may. Firstly how do you explode and create a component? I’ve tried to do that with my first model, but it retains the file structure.
Secondly, how did you do your square array? Was it with an extension, or did you create a linear array, and then multiply it?
