■ Finding All Drawing Objects in a Spe-
cified Location (page 1238)
■
Combining Drawing Query Conditions
(page 1255)
NOTE This procedure applies only to drawing objects. For information on filtering
geospatial feature data by property, see
Using Expressions to Select Feature Data
(page 1131).
To retrieve drawing objects based on their object data
1 In Map Explorer (page 2068), under Current Drawing, right-click Current
Query, and then click Define.
2 Click Data.
3 In the
Data Condition dialog box (page 1836), select the type of data to
query.
4 Specify the specific data to query.
■ For object class, select the object class of the objects to retrieve. Then,
under Properties, select the specific properties to query.
■ For object data, select the table and field to query.
Note that if two attached drawings have a table with the same name,
AutoCAD Map 3D recognizes only the fields defined in the first
drawing you activate.
■ For database link data, select the link template associated with the
objects you want to retrieve. Under Key Columns, select the key
column to query.
Because a query retrieves objects from attached drawings, only link
templates defined in your attached drawing are displayed in the list.
■ For block attributes, select the block to query. Under Attribute Tags,
select the attribute tag to query, or select * from the Blocks list to see
a list of all the attribute tags of all the blocks in the active drawing.
5 Specify the condition that the data must match by selecting an operator
and entering a value in the Value field.
For example, to find all values greater than 8, select the > operator and
enter 8 in the Value field.
For information on using wild cards, see
Wildcard Characters (page 1537).
