4. From the Data Extraction - Begin (Page 1 of 8) dialog box, select the
Create A New Data Extraction option, and click Next.
The Save Data Extraction As dialog box opens.
5. Browse to your Chapter 9 Training Dataset folder within the Save
Data Extraction As dialog box, enter RoomArea in the File Name
textbox, and click Save.
The Save Data Extraction As dialog box closes, and you're taken to
the second step within the Data Extraction Wizard.
6. Choose the Drawings/Sheet Set option, check the Include Current
Drawing check box within the Data Extraction - Define Data Source
dialog box, and click Next.
Although in this case you're extracting data only from the current
drawing, data extraction tables can pull information from multiple
drawings all at once. This feature is useful when using data extrac-
tion tables for quantity takeoffs when each floor of a multilevel build-
ing is stored in a separate drawing.
7. Next, the Data Extraction Wizard asks you to specify the objects from
which to extract data. In this case, you're interested only in the data
contained within the A-ROOM-INFO block.
a. Uncheck the Display All Object Types check box, and choose the
Display Blocks Only option.
b. Right-click on one of the objects listed within the Objects por-
tion of the dialog box, and choose Uncheck All.
c. Select the check box next to the A-ROOM-INFO object.
The Data Extraction - Select Objects (Page 3 of 8) dialog box should
look like Figure 9.75. After selecting the A-ROOM-INFO block, click
Next to move onto the next step of the wizard.
8. Next, you need to specify the attributes (properties) you want the data
extraction table to include. In this case, you're only interested in the
three block attributes contained within the A-ROOM-INFO block.
a. Click the Category header to sort the properties by category type.
This will bring the Attributes category to the top of the list.
b. Uncheck the check box next to the RM-NAME, RM_AREA, and
RM_FLOOR properties.
