Using Map 3D we can easily attach our drawing objects to a
database using the tools provided to us in the Map Explorer.
What we first need to establish is what dwg objects we want to
connect data to. In our case we have 5028 fire hydrants that
have nothing associated with them except the fact that they are
fire hydrants. We want to change that by connecting them to the
Microsoft Access Database that contains all the info that
describes them. This is much easier than it sounds.
First we start off by simply opening or querying in all the dwg
data necessary.

Once we have the dwg objects we wish to use we now will want to
browse and find our data by right clicking the data sources
option on our task pane. This data could be in multiple formats
including .xls and .mdb files.

Once we choose the attach option that is given to use we can now
grab our data. Once we attach this data the dialog will
disappear.

Once we make a decision the data file will show under the data
sources tree in the task pane. The only job we have left is to
connect the two sources of info into one.

We do this by defining a link template that can also be found at
the bottom of the task pane, and is accessed by the same method
as the data sources, by right clicking.

Once we go through the dialog and choose the common field which
is held in both the dwg and database we can make a connection
and all the objects will be connected straight to the database.
In this case we will be using the hydrant number which is
provided with every block and also resides in the data.

When dealing with large numbers of objects in a drawing
connecting to a form of data may make navigating these items
specifically a much more enjoyable task. Now you can see that by
adding data to these objects we can now actually view the data
table straight from the Task Pane and navigate through specific
objects by choosing their properties in the data table and using
the Auto Highlight and Zoom tools given to us in the table, as
seen below. We can even choose for the item to be highlighted
upon selection in the data table.

We can also sort data by choosing the items on screen and only
having the form show the records for the selected objects.

These options are also held in in the highlight pull down of the
data table.
Map 3D 2009 makes it really easy
on us (in many different other ways also) to get the data we
need into our Maps, Drawings and Models. This type of function
is very helpful in many different situations and can be used by
almost anyone keeping track of specific objects in a plan or
model. The use of this function is also fully available in Civil
3D 2009 (all of Map 3D 2009 is in Civil 3D 2009).
