Desktop Help 10.0 - Update Diagram (Schematics)

Zusammenfassung

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.

Verwendung

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 geometric network data. 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 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, 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 can be specified, even if all the feature layers related to the geometric network (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	Erläuterung	Datentyp
in_diagram	The schematic diagram to be updated.	Schematic Diagram; 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 analyst 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 geometric networks, when the Input Data parameter is not specified, the Update Diagram tool works from the initial set of features/objects used to generate the diagram or from the updated 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.	TableView; Layer; Data Element
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 or NO_KEEP_MANUAL_MODIF. 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): MERGE_NODES or NO_MERGE_NODES, KEEP_MANUAL_MODIF or NO_KEEP_MANUAL_MODIF Diagrams generated from features organized into a geometric network (Standard builder): REBUILD or APPEND, KEEP_MANUAL_MODIF or NO_KEEP_MANUAL_MODIF. KEEP_MANUAL_MODIF —Default option. Use this if you want the schematic features that have been removed/reduced from the diagram to not reappear and the edited connections to be kept in the updated diagram. NO_KEEP_MANUAL_MODIF —Use this if you want those removed/reduced schematic features and the reconnected schematic feature links to be restored after the update. NO_MERGE_NODES —Default option for diagrams based on the Network Dataset builder. Use it so no schematic feature node is merged in the updated diagram. MERGE_NODES —Option available for diagrams based on the Network Dataset builder. Use it so network element junctions that occur several times along the resultant route of a route analysis can be represented by a single schematic feature node in the updated schematic diagram. This option also allows you to merge midspan junction elements when they are at the same position in the case of a service area analysis. REBUILD —Default option available for diagrams based on the Standard builder when input data is set. Use this option if you want the specified schematic diagram to be completely rebuilt according to the specified input feature layers, feature classes, or object tables. APPEND —Option available for diagrams based on the Standard builder when input data is set. Use this option if you want to keep all the schematic features that have been initially used to generate the specified schematic diagram; add schematic objects associated with the specified input feature layers, feature classes, or object tables; and update all the diagram content	String
