Hi,

Go to the Apps menu, select the Modules for which you need to get the information from the Apps Tree View, click on Print - > Technical Guide.

In the Report, you will get information like Models and Fields, Views, Menus etc.

See: Print Modules Technical Guide in Odoo

If this is not okay for you you can go to Models Menu, in Settings -> Technical -> Database Structure -> Models, in the field "In Apps" you can see in which all modules the models has been used.

Thanks
