You can change the interface language, the language for Help, and the language for models all at the same time.
Procedure
The language is changed.
If content such as Help or model content is not available in the selected language, it is displayed in the alternative language. The alternative language is the database language in which database content is displayed if attribute values are not specified in the database language used. Using this, for example, you prevent names from being displayed as (Untitled) if they have not been specified in the relevant database language. When you create a database, English (United States) is selected automatically.
