It doesn't work quite like that. ACad generates a GUID (Globally Unique ID)
and actually builds a database in code. Every object in the ACad drawing has
a GUID. The database is an MDB, but ACad won't recognize any file that it
doesn't generate. ACad also can build an Excel file to get the room areas
and perimeters.
