Cubical maps and their associated data can be easily duplicated in one of three ways. When duplicating a cubical map a new cubical map is created as a copy of the original. The new cubical map will be created in the same category as the original with "Copy of" appended to its name. For example a cubical map named "Original Map" would be duplicated as "Copy of Original Map".
Select a cubical map in the Navigation Tree and from the Main menu choose Edit → Duplicate.
Right-click on a cubical map in the Navigation Tree and choose Duplicate from the context menu.
Select a cubical map in the Navigation Tree and press the keyboard shortcut Ctrl+D.
