Update Diagram

Summary

Updates a schematic diagram.

Depending on the schematic builder, the diagram update can be based on feature layers, feature classes, object tables, a solved network analysis, or an XML file.

Usage

• The Input Data parameter is mandatory for diagrams working with the Network Dataset builder and XML builder. It is optional for diagrams working with the Standard builder when it is configured to operate from a geometric network or network dataset. It must not be specified for diagrams that work with the Standard builder when it is configured to operate from custom queries.

• When using the Update Diagram tool on diagrams implemented by the Standard builder that have been generated from a geometric network trace, the update operates from the updated trace result based on the trace parameters that persisted in the schematic dataset the first time the diagram was generated from a highlighted trace.

• When the update must operate from features that compose a geometric network or network dataset, it is not necessary to specify all the feature layers in the Input Data parameter. If the Add connected nodes option is specified for the Standard builder properties, only the feature layers related to edge features or edge network elements can be specified, even if all the feature layers related to the geometric network or network dataset (junctions and edges) will be used for update.

• If a particular layout was saved for the specified schematic diagram, the schematic features that were in the diagram before updating are displayed according to their last saved position, and new schematic features that may have been introduced during the update are positioned at their geographic coordinates.

Syntax

UpdateDiagram_schematics (in_diagram, {in_data}, {builder_options})

Parameter	Explanation	Data Type
in_diagram	The schematic diagram layer to be updated.	Schematic Layer
in_data [in_data,...] (Optional)	The input data on which the diagram update will be based. The Input Data parameter is not required for all predefined builders; it's an optional parameter: For diagram templates that work with the Standard builder configured to operate from custom queries, no input tables must be set. For diagram templates that work with the XML builder, the Input Data parameter must reference an XML file. For diagram templates that work with the Network Dataset builder, the input data must be specified. It must reference a unique network analysis layer. If the related network analysis is not performed, Schematics tries to perform it before using the solved analysis layer as input. For diagram templates that work with the Standard builder configured to operate from a geometric network or a network dataset, when the Input Data parameter is not specified, the Update Diagram tool works from the initial set of network features/objects used to generate the diagram or from the updated geometric network trace result based on the trace parameters that persisted in the schematic database if the diagram was generated from a highlighted trace. When the Input Data parameter is specified, it must reference at least a feature layer, feature class, or object table so the update operates on this data according to the Builder Options value.	Table View;Data Element;Layer
builder_options [builder_options,...] (Optional)	The schematic builder update options. Update options are optional. They depend on the builder related to the diagram template that implements the specified schematic diagram: Diagrams generated from custom queries (Standard builder): KEEP_MANUAL_MODIF, NO_KEEP_MANUAL_MODIF, or REFRESH. Diagrams generated from XML data (XML builder): KEEP_MANUAL_MODIF or NO_KEEP_MANUAL_MODIF. Diagrams generated from solver results on network datasets (Network Dataset builder): NO_MERGE_NODES;KEEP_MANUAL_MODIF, NO_MERGE_NODES;NO_KEEP_MANUAL_MODIF, MERGE_NODES;KEEP_MANUAL_MODIF or MERGE_NODES;NO_KEEP_MANUAL_MODIF. Diagrams generated from features organized into a geometric network or a network dataset (Standard builder): When the Input Data parameter is not specified—KEEP_MANUAL_MODIF, NO_KEEP_MANUAL_MODIF, or REFRESH When the Input Data parameter is specified—REBUILD;KEEP_MANUAL_MODIF, REBUILD;NO_KEEP_MANUAL_MODIF, APPEND;KEEP_MANUAL_MODIF, APPEND;NO_KEEP_MANUAL_MODIF, APPEND_QUICK;KEEP_MANUAL_MODIF or APPEND_QUICK;NO_KEEP_MANUAL_MODIF KEEP_MANUAL_MODIF —Default option for diagram based on the XML builder or on the Standard builder when no input data is set. Use it to synchronize the input diagram content either against the original selection/trace/query used to initially generate this diagram—Standard diagram—or from an updated version of the XML input data initially used to generate it—XML diagram—whereas the schematic features that may have been manually removed/reduced/reconnected are kept in the updated diagram. NO_KEEP_MANUAL_MODIF —Option available for diagrams based on the XML builder or on the Standard builder when no input data is set. Use it to synchronize the input diagram content either against the original selection/trace/query used to initially generate this diagram—Standard diagram—or from an updated version of the XML input data initially used to generate it—XML diagram—whereas the schematic features that may have been manually removed/reduced/reconnected are restored in the updated diagram. REFRESH —Option available for diagrams based on the Standard builder when no input data is set. Use it to simply refresh the attributes for all schematic features in the input diagram to the current state of the related network features in the geometric network or network dataset feature classes. REBUILD;KEEP_MANUAL_MODIF —Default option available for diagrams based on the Standard builder when input data is set. Use this option if you want the input diagram to be completely rebuilt according to the specified input feature layers, feature classes, or object tables, whereas the schematic features that may have been manually removed/reduced/reconnected are kept in the updated diagram. REBUILD;NO_KEEP_MANUAL_MODIF —Option available for diagrams based on the Standard builder when input data is set. Use this option if you want the input diagram to be completely rebuilt according to the specified input feature layers, feature classes, or object tables, whereas the schematic features that may have been manually removed/reduced/reconnected are restored in the updated diagram. APPEND;KEEP_MANUAL_MODIF —Option available for diagrams based on the Standard builder when input data is set. Use this option if you want to append schematic features associated with the specified input feature layers, feature classes, or object tables with a full synchronization of the input diagram content, whereas the schematic features that may have been manually removed/reduced/reconnected are kept in the updated diagram. APPEND;NO_KEEP_MANUAL_MODIF —Option available for diagrams based on the Standard builder when input data is set. Use this option if you want to append schematic features associated with the specified input feature layers, feature classes, or object tables with a full synchronization of the input diagram content, whereas the schematic features that may have been manually removed/reduced/reconnected are restored in the updated diagram. APPEND_QUICK;KEEP_MANUAL_MODIF —Option available for diagrams based on the Standard builder when input data is set. Use this option if you want to append schematic features associated with the specified input feature layers, feature classes, or object tables with a partial synchronization of the input diagram content, whereas the schematic features that may have been manually removed/reduced/reconnected are kept in the updated diagram. APPEND_QUICK;NO_KEEP_MANUAL_MODIF —Option available for diagrams based on the Standard builder when input data is set. Use this option if you want to append schematic features associated with the specified input feature layers, feature classes, or object tables with a partial synchronization of the input diagram content, whereas the schematic features that may have been manually removed/reduced/reconnected are restored in the updated diagram. NO_MERGE_NODES;KEEP_MANUAL_MODIF —Default option for diagrams based on the Network Dataset builder. Use this option to update the input diagram from the specified solved network analysis layer without merging nodes that occur several times in this layer, whereas the schematic features that may have been manually removed/reduced/reconnected are kept in the updated diagram. NO_MERGE_NODES;NO_KEEP_MANUAL_MODIF —Option available for diagrams based on the Network Dataset builder. Use this option to update the input diagram from the specified solved network analysis layer without merging nodes that occur several times in this layer, whereas the schematic features that may have been manually removed/reduced/reconnected are restored in the updated diagram. MERGE_NODES;KEEP_MANUAL_MODIF —Option available for diagrams based on the Network Dataset builder. Use it to update the input diagram from the specified solved network analysis layer and merge nodes that occur several times in this layer, whereas the schematic features that may have been manually removed/reduced/reconnected are kept in the updated diagram. MERGE_NODES;NO_KEEP_MANUAL_MODIF —Option available for diagrams based on the Network Dataset builder.
