[AccessD] Visio File Mappings

It is quite easy to do however, only certain versions of Visio support it.

If you can't find the following commands your version probably doesn't
support it:

On the File menu, point to New, point to Database, and then click Database
Model Diagram. 
On the Database menu, click Reverse Engineer. 
On the first screen of the Reverse Engineer Wizard, do the following: 
Select the Microsoft Office Visio database driver for your database
management system (DBMS). If you have not already associated the Visio
database driver with a particular 32-bit ODBC data source, do so now. 
Select the data source of the database you're updating. If you have not
already created a data source for the existing database, do so now.
