I realise that abbilden and nachbilden mean something similar, i.e. to copy or to reproduce. However, is there a specific context in which it is more appropriate to use one or the other?
"Abbilden" means more like making a picture of something. "Nachbilden" means more to build something as close to the original as possible.
The result of "Abbilden" is something else that shows the original object, the result of "Nachbilden" is something that should look or feel as close to the original object as possible.
