Autodesk 15606-011408-9005 Tutorial - Page 117

You must have AutoCAD Map 3D to create object data, but anyone who uses the free Autodesk® Design Review software can view it. For example, a field worker can view a DWF™ version of a sewer map in Autodesk® Design Review. To see information about a sewer pipe, the worker holds the cursor over that pipe. The information is available without obscuring the map itself. The drawings in this tutorial have object data tables with information already entered. In this exercise, you use object data (page 313) as a query condition. In a later exercise, you use object data to create feature classes in a new data format. NOTE This exercise uses the Redding.dwg map you created and modified in Exercise 1: Attach source drawings (page 99). To create a query based on object data 1 If the Redding.dwg map from the previous exercise is not still open, reopen it. 2 In Map Explorer, under Current Drawing, right-click Current Query, and click Define. 3 In the Define Query of Attached Drawing(s) dialog box, do the following: ■ Under Current Query, click Clear Query. ■ Under Query Type, click Data. 4 In the Data Condition dialog box, do the following: ■ Select Object Data. ■ Under Tables, select SEWER_PIPES. ■ Under Object Data Fields, select PIPESIZE. ■ In the Expression area, under Operator, select >. Under Value, enter 8. Exercise 5: Query object data | 109
