How could I set the classes' default language

[jordanliu]

I need create a lot of classes in c++. But the default language is java and it is not possible to change multiple classes' default language. To change them one by one is a nightmare.

Could I set c++ as default language or could I select all of them to change the language?

Thanks

The default language (for a model) can be set either in the code generation toolbar, or in the Code Datatypes dialog.

You can change the languages for all classes in a package from the Project Browser.  (Context menu | Code Engineering | Reset Options for this Package.)
