When you attach a drawing
to a map, objects in the drawing do not appear in the map immediately.
You must query them in. The drawing file you attached is a map of
California with polygons defined for each county. Since the city
of Redding is in Shasta County, you add the Shasta County boundaries
to your map. You can query in data based on location, properties,
or data. In this case, query the name of the county, which is stored
as object data.
exercise uses the BuildMap1.dwg map
you created and modified in the previous exercises.
To query in drawing data
- In the BuildMap1.dwg file,
in Display Manager,
click Data Add
Drawing Data Query Source Drawing.
- In the Define Query Of Attached
Drawings dialog box, under Query Type, click Data.
- In the Data Condition dialog
box, select the Object Data option.

Define the data condition
for the query.
The query is case sensitive. Be sure to enter
it as shown.
- Click OK in the Data
Condition dialog box, and then click OK again
to execute the query.
- In the Tool-based Ribbon Workspace, click View
The Shasta county boundaries are now displayed
in the map, and an Attached Drawing Element layer
is displayed in Display Manager.
- Save your work. Click Save.
might see an alert as you work through the remainder of the tutorial. It
warns that the association between queried objects in the current
and attached drawings is not retained once the current drawing file
is closed. This message reminds you to save back any changes you
make to the original drawing file. Since you do not edit the Shasta
County drawing in this tutorial, you can safely ignore the alert.
