External Database Links
Databases are commonly used to store large amount of data, such as equipment specifications, catalogue data,
and maintenance manuals.
You can connect to external databases directly from your Navisworks files, and create links between objects in
the scene and fields in the database tables to bring through extra properties.
Any database with a suitable ODBC driver is supported, but the properties for the objects in the model must
include unique identifiers to the data in the database. For example, for AutoCAD-based files, entity handles can
be used.
You can have as many database links as you want, but they all should have unique names. To use a database
link, you need to activate it first.
Database links can be saved inside Navisworks files (NWF and NWD). You can also save database links globally,
making them persistent across all Autodesk Navisworks sessions. The global connection information is saved on
the local machine. If the associated database is available on loading the NWF/NWD file, the link automatically
establishes itself when an object is selected. On selecting an object, if the database is available, and there is data
associated with the object, Autodesk Navisworks adds an appropriate database tab to the Properties window, and
displays the appropriate data.
NOTE To be able to display the data, you need to configure the connection details. You may need a database
administrator to do this, as a knowldege of the database being connected to is required. You can use Navisworks tags
in connection strings and SQL statements.
Data linked from a database connection can be extracted and embedded as static data within the published NWD
file. It also can also be included in object searches, and can be used with the Clash Detective tool as part of the
clash criteria.
You can export database links, and share them with other users.
To add a database link
1 If you want to add a database link to the Navisworks file:
