Dictionaries
Each drawing contains one root dictionary, the named-objects dictionary.
Within the root dictionary, you can create dictionaries, which can also contain
dictionaries. This allows you to create a hierarchical structure of
dictionaries.
Dictionaries:
- contained in the root dictionary form the first level.
- in the first level contain objects and can contain dictionaries that
form the second level.
- in the second level typically contain only objects, but can also contain
dictionaries that form the third level, etc.
The number of levels of
dictionaries is unlimited.
