Define Range Table dialog box

Use this dialog box to create, rename, or delete range tables.

A range table specifies a range of actions to take depending on the actual value of object data or properties associated with drawing objects.

• For property alteration, specify different alterations for a property depending on the value of the property. For example, you could specify that all buildings under two stories be colored blue, all buildings two stories to ten stories be colored green, and all buildings above ten stories be colored red.
• For an output report, specify different actions to take depending on the value of the data. For example, you could specify that if a lot is valued at less than $10,000, report the value in the Land Value A column of your database; if the lot is valued at over $10,000, report the value in the Land Value B column.

Create range tables and save them with the current drawing to use again.

Range Table area

Select an existing table, rename a table, create a new table, or delete a table.

Range Table list

Current Range Table Definition area

Use this area to view, edit, or delete rows in the range table.

Current Range Table Definition list

Copy the selected row to the Condition section of the dialog box, where you can modify it.

When you finish modifying the condition, click Add To List to update the row in the Current Range Table Definition list.

Delete the selected row.

Clear List

Delete all rows from the current range table.

Expressions in the Current Range Table Definition list are evaluated from top to bottom, that is, in the order you enter them. As soon as one condition is evaluated as TRUE, AutoCAD Map 3D toolset stops evaluating, ignores the remaining expressions, and returns the value associated with the TRUE condition in the range table.

For example, assume you enter the following expressions:

If < 0 Return: Low

If < 15 Return: Medium

If < 30 Return: High

If < 45 Return: Very High

With a value of 20, the first condition evaluates to FALSE because 20 is not less than 0. The second condition also evaluates to FALSE since 20 is not less than 15. However, the third condition evaluates to TRUE since 20 is less than 30, and the value returned by the range table is High. The last condition, although TRUE, is ignored.

Condition area

Edit an existing row, or create a new one.

• To edit an existing row, select the row in the Current Range Table Definition list and click Edit. When you finish, click Update.
• To create a new condition, select an operator, specify an expression and a return value, and click Add.
