Topology Thematic Mapping dialog box

Use this dialog box to create a thematic map that uses color, fill, line format, symbols, or text to display information about a topology.

You can use any topology that can be loaded into the current, open drawing. The topology can be stored entirely in the current drawing, or it can loaded from attached, source drawings.

Objects of Interest

Specify the objects to modify.

Topology Name

Select the topology containing the objects to modify. If the topology is not loaded, click Load and load it.

Limit To Location

Finds objects only if they are in a specified location. To define the location, click Define.

If you select Limit To Location, the objects must be in the specified topology and within the specified location.

Thematic Expression

Select the data to use to determine the modification. This can be data stored in an object data table, or stored in an external database, or based on the properties of the object.

Expression

Click the Expression to display the Thematic Expression dialog box, where you can select the property or data to use.

Note The Link Template list includes only link templates for active source drawings. If the link template you want is not listed, be sure it is defined in the source drawing. In addition, be sure the appropriate data source is attached and connected in the current drawing.

Display Parameters

Specify the property to alter, and specify the ways to alter the property.

Display Property box

Select how o display the data. You can display ranges of data using different colors, fills, line formats, symbols (blocks), or text.

You can set an option to determine whether the fill is an associative hatch object. See the Query tab of the Autodesk Map Options dialog box.

Range Division options

Specify whether the data is discrete or continuous.

Select Continuous for numerical data that can include any value in a continuous range. Click Define to specify how to divide the range. For example, you could divide property values into five continuous groups: low, medium-low, medium, medium-high, and high. Select Discrete for numerical values that are not continuous or for character values. Click Define to specify the possible values.

Define

Display the Thematic Display Options dialog box, where you can specify the property alteration for each range (for continuous data) or for each possible value (for discrete data).

Only objects that fall into one of the defined ranges will be modified. If an object is included in the thematic map, but it does not have data or properties that fall into one of the ranges you define, the object will appear in the map but will not be altered.

Options

Load an existing thematic query or save the current query.

Load

Load an existing query.

If the query includes statements not supported by thematic queries, those statements are skipped.

Save

Save the current thematic query definition.

If the query definition includes legend information, save the query as an external query. Internal queries do not retain legend information.
