Object 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 objects

Specify the objects to modify, the data to use, and the properties to use to display the data.

Because this command modifies objects as they are retrieved by the query, the objects must be in source drawings and must not be already queried into the current drawing.

Objects of Interest

Specify the objects to modify.

If more than one option is selected, the objects must meet all the selected criteria. For example, if you select both Limit To Location and Limit To Layers, the objects must be on the specified layer and within the specified location.

Limit To Location

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

Limit To Layers

Finds objects only if they are on selected layers. To select layers, click Layers.

Limit To Blocks

Finds objects only if they are in selected blocks. To select blocks, click Blocks.

Thematic Expression

Specify the data to use when determining how to alter the objects.

Expression

Click Expression to display the Thematic Expression dialog box, where you can select the property, object data, or external 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 how to alter the objects.

Display Property box

Select how to 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

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.
