The Append new features to the active diagram option works on network features that remain highlighted in one of the map document's data frames after a tracing or selection operation on the network. It allows you to append those network features in the active diagram with a partial or complete synchronization of the diagram content to the associated network features.
After checking this option, you need to specify the two following settings:
- Which input network data you want to be appended to your schematic diagram.
You can append two types of input to a diagram:
- A set of network features currently selected in a data frame
- The result of a geometric network tracing operation in memory
- How you want to synchronize the diagram content.
There are two different modes of synchronization:
- A full synchronization—synchronize the whole diagram content to the current state of all the associated GIS network features in the geodatabase.
- A partial synchronization—synchronize the diagram's part where the features are appended only.
In all cases, the update process is performed as follows:
- The schematic features contained in the diagram that don't come from custom queries are loaded in memory.
- The current set of network features highlighted in the map is analyzed, and depending on the Full Diagram Synchronization option chosen, the builder operates as follows:
- When the Full Diagram Synchronization option is checked:
- Any schematic feature initially contained in the diagram that is still associated with an existing GIS feature in the geodatabase is updated; its attributes and initial geometry are refreshed, and its current geometry is reinitialized if the diagram was not saved.
- Any schematic feature initially contained in the diagram that is no longer associated with an existing GIS feature in the geodatabase is removed from memory.
- New schematic features coming from GIS features highlighted in the map are created in memory. Their attributes are evaluated, and their topology and geometry are initialized.
- When the Full Diagram Synchronization option is unchecked (default):
- Only the schematic features initially contained in the diagram associated with input GIS features currently highlighted in the map are updated; their attributes and initial geometry are refreshed, and their current geometry is reinitialized if the diagram was not saved.
- New schematic features coming from GIS features highlighted in the map are created in memory. Their attributes are evaluated, and their topology and geometry are initialized.
- When the Full Diagram Synchronization option is checked:
- Then, if schematic rules are specified for the related diagram template, they are executed on all the in-memory schematic features.
- If the Persist manually removed, reduced or reconnected features check box is checked, the removal, reduction, and reconnecting operations are reexecuted.
- If there is a default schematic layout algorithm configured for the diagram template and the diagram has no saved layout, the algorithm is reexecuted, and the geometry for all the in-memory schematic features is updated accordingly.
- The schematic features in memory are saved in the schematic feature classes in the schematic dataset.
- The active schematic diagram is then refreshed with the new schematic dataset content.
Precaución:
For diagrams initially generated from tracing operation results, the tracing operation parameters are stored in the schematic database during the generation process. If tracing operations are never reexecuted when updating diagrams using the Append new features to the active diagram option, the initial tracing operation parameters always persist in the schematic database. It is recommended that diagram generation based on initial tracing results never be done in a haphazard way, and synchronization against the original trace must work. Note that because the initial tracing operation parameters are always kept, a new update of the diagram using the Synchronize against the original selection/trace/query option may cause the appended schematic features to be lost when they are not returned by the tracing result. The following table shows the state of the preserved tracing operation parameters at the end of updates when using the Append new features to the active diagram option with the Current Selection or Current Trace option:
Diagram initially generated from a trace | Diagram initially generated from a GIS feature selection set | |
---|---|---|
Append from Current Selection | The initial trace parameters that persist in the schematic database before updating are kept after updating, but this initial trace is not reexecuted during the update. | No trace parameters are preserved in the schematic database. |
Append from Current Trace | The parameters related to the appended trace are not kept in the schematic database. The initial trace parameters persist after updating, but this initial trace is not reexecuted during the update. | The parameters related to the appended trace are not maintained in the schematic database. |
