Add Representation (Cartography) (ArcInfo only)
Release 9.2 Last modified July 13, 2007	Print all topics in : "Tools"

Related Topics

Adds a feature class representation to a geodatabase feature class.

Two new fields with the specified field names will be appended to the input feature class attribute table to identify the representation rules that govern how each category of features will be portrayed, and to hold any feature-specific overrides to these rules.

Usage tips

The input must be a geodatabase feature class.
Specify an import rule layer to import representation rules from an existing layer file that symbolizes features with a feature class representation. All the representation rules of the import rule layer file will be copied into this feature class representation.
If the import rule layer has the same source feature class as the input feature class, you can check Assign Rule IDs (or use the ASSIGN option in a script or at the command line) to assign representation rules to features to match the RuleID assignments of the import rule layer.
If an import rule layer is not specified, all features will be assigned to a single default representation rule.
If an import rule layer is specifiied, but the Assign Rule IDs option is unchecked (or the NO_ASSIGN option is used in a script or at the command line), all features will be assigned to a single default representation rule.
If an import rule layer is specified and the Assign Rule IDs option is checked (or the ASSIGN option is used in a script or at the command line), all features will be assigned to a representation rule based on the symbol choices listed under the renderer type (ie: Categories-Unique values) specified on the layer file.
If <all other values> is used to symbolize data, that symbol will become Rule ID 1 when a representation is added.

AddRepresentation_cartography <in_features> <representation_name> <rule_id_field_name> <override_field_name> {STORE_CHANGE_AS_OVERRIDE | MODIFY_FEATURE} {import_rule_layer} {ASSIGN | NO_ASSIGN}

Parameter	Explanation	Data Type
<in_features>	The input geodatabase feature class to which a new feature class representation will be added.	Feature Layer
<representation_name>	The name of the feature class representation to be added.	String
<rule_id_field_name>	The name of the RuleID field, which will hold a reference to the representation rule for each feature.	String
<override_field_name>	The name of the Override field, which will hold overrides to representation rules for each feature.	String
{STORE_CHANGE_AS_OVERRIDE \| MODIFY_FEATURE}	Specifies what will happen to the supporting feature class geometry when features are modified with the representation editing tools. STORE_CHANGE_AS_OVERRIDE — Geometry modificatiuons made to features with the representation editing tools or using any of the geoprocessing tools in the Cartography toolbox will be stored as shape overrides in the Override field. Supporting feature class geometry (stored in the Shape field of the feature class) will be unaffected. This is the default. MODIFY_FEATURE_SHAPE — Geometry modifications made to features with the representation editing tools, or using any of the geoprocessing tools in the Cartography toolbox, will modify the supporting feature class geometry (stored in the Shape field of the feature class.) No shape overrides will be stored.	String
{import_rule_layer}	A feature layer that symbolizes features with a feature class representation, from which the representation rules are imported.	Layer
{ASSIGN \| NO_ASSIGN}	Specifies whether or not to assign representation rules to features to match the RuleID assignments of the import rule layer. This option applies only when Import Rule Layer is specified. ASSIGN — assign RuleIDs to features to match the import rule layer. This is the default. NO_ASSIGN — Specifies not to match RuleIDs to features from the import rule layer. Features will be assigned to the default representation rule instead.	Boolean

Parameter	Explanation	Data Type
in_features (Required)	The input geodatabase feature class to which a new feature class representation will be added.	Feature Layer
representation_name (Required)	The name of the feature class representation to be added.	String
rule_id_field_name (Required)	The name of the RuleID field, which will hold a reference to the representation rule for each feature.	String

Supporting feature class geometry (stored in the Shape field of the feature class) will be unaffected. This is the default. MODIFY_FEATURE_SHAPE — Geometry modifications made to features with the representation editing tools, or using any of the geoprocessing tools in the Cartography toolbox, will modify the supporting feature class geometry (stored in the Shape field of the feature class.) No shape overrides will be stored.	String
import_rule_layer (Optional)	A feature layer that symbolizes features with a feature class representation, from which the representation rules are imported.	Layer
assign_rule_id_option (Optional)	Specifies whether or not to assign representation rules to features to match the RuleID assignments of the import rule layer. This option applies only when Import Rule Layer is specified. ASSIGN — assign RuleIDs to features to match the import rule layer. This is the default. NO_ASSIGN — Specifies not to match RuleIDs to features from the import rule layer. Features will be assigned to the default representation rule instead.	Boolean
