ISchematicRouteNodeReductionRule Interface

Provides access to members that manage the generic Schematic Route Node Reduction rule.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Schematics Extension.


The Route Node Reduction rule allows you to generate schematic diagrams after all route nodes or certain route nodes related to a given node schematic feature class have been removed along a route while preserving the topology. Even if this rule works on any schematic diagram, the Route Node Reduction rule has been specifically developed to reduce route nodes contained in schematic diagrams generated from a network layer containing a resulting route. For these diagrams, the network analysis cost attributes coming from the solved network feature layer used in input for the diagram generation (for example, ArriveTime, DepartTime, Attr_Meters, Attr_Minutes, Status, CurbApproach, and so on) are transferred on the schematic element during the generation process and stored in the schematic element class. When route nodes are reduced using the Route Node Reduction rule, these attributes are accumulated during the rule execution.


Read/write property ReduceAngle Reduction angle of the rule.
Read/write property ReduceByAngle Indicates if the reduction reduces all the nodes.

Route nodes are nodes with degree two—that is, two links connect these nodes.
