For starters a quick example and probably needs a better example and description, but something I see is people take drawings received from others copy, paste, rotate, and combine together to get result wanted.
Adapter
Convert the interface of a drawing into another interface clients expect. Adapter lets drawings work together that couldn't otherwise because of incompatible interfaces.
Example:
Adaptee drawing - a one to one drawing file with layer properties updated and blocks redefined of drawings received from a client.
Adaptor drawing - a drawing that references all the Adaptee's drawing and applies the transformation and changes are only done by updating the adaptee's.
