To convert a patch into an internal patch, select the patch box and press
The copy of the blue patch that is created is fully autonomous from the master.
Converting a red patch into a blue patch amounts to assigning it a reference in the workspace.
To copy and convert an internal patch into a global – blue – patch, drag and drop the red patch in the workspace.
Once the conversion is done, the abstraction as well as its reference will be equally affected by possible modifications.
