Displaying the Main Menu
The Main Menu is displayed when the 3di opens, and cannot be closed or minimised. If the Main Menu has become hidden behind other objects on the screen, you can bring it to the front in two ways:
click the Main Menu button on the 3di toolbar
or press <Ctrl + Shift + M> (think of M-enu)
The main menu with the Training5 backend loaded The main menu shows the name of the current backend or 'no backend' if none is loaded.
Using the Main Menu buttons
Select and open backend

Recall from frontend and backends that patient cases are stored in a backend, and that each backend subfolder lives in a backends source folder.
To select a backend from the Backends folder already shown in Current source of backends:
select the backend in Backends in source
click the button Open selected backend
To select a backend from an existing but different backends source (for example, a folder on a removable drive):
click the button Browse for new source
navigate to the required existing Backends folder and ensure it is highlighted
click OK in the browse dialog
notice that the new Backends folder is now displayed in Current source of backends, and that there is a new list of available backends in Backends in source
select the desired backend in Backends in source
click the button Open selected backend
Create and open backend

The exact procedure depends upon where you wish to create your new backend: you will need to choose one of the possibilities numbered i) to iii) below.
However, naming your backend is a part of all three procedures, and should take account of the following:
the name may have up to 10 characters drawn from A-Z, a-z, 0-9
the name must not be amongst any listed in Backends in source
although different Backend sources can contain identically named backends, the potential for confusion is minimised if backend names are unique
If your chosen procedure is successful, the Main Menu will display the name of your new backend; otherwise error messages will suggest possible problems and the Main Menu will display ‘no backend’.
Choose whichever one of the following three possibilities matches your need:
i) If you wish to create your new backend in the Backends folder already shown in Current source of backends:
enter a name for your backend in Enter name for new backend
click the button Create (and open) backend in current source
ii) If you wish to create your backend in an existing but different Backends source folder (for example, a folder elsewhere on your hard disc or on a removable drive):
click the button Browse for new source
navigate to the required existing Backends folder and ensure it is highlighted
click OK in the browse dialog
notice that the new backends folder is now displayed in Current source of backends, and that there is a new list of backends in Backends in source
enter a name for your backend in Enter name for new backend
iii) If you wish to create your backend in a newly created Backend source folder (for example, a folder elsewhere on your hard disc or on a removable drive):
click the button Create new source
navigate to the folder which is to contain your new Backends folder and ensure it is highlighted
click OK in the browse dialog
notice that the new backends folder is now displayed in Current source of backends, and that there is an empty list of backends in Backends in source
enter a name for your backend in Enter name for new backend
note that in the example above, a Backends folder will be created in the Research folder, and within that will be created the folder for your new backend
Add and interview patients

This button opens the Case Manager form. Refer particularly to:
Routes: create and manage

Using the Close 3di5 button leaves Microsoft Access running, but with no file open. You may prefer to close the 3di simply by closing the application window by clicking the Close icon at the top-right of the window – just as you would close down Microsoft Word or Excel.
