ISchematicAlgoForceDirected Interface

Provides access to members that control the Force Directed schematic algorithm.

Product Availability

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


The Force Directed algorithm uses a physical analogy to draw graphs by considering a graph a force system in which it tries to locally minimize the energy. It searches for an equilibrium state of the force system—a position for each schematic node where the total force on each node is zero


Read-only property AlgorithmCLSID The CLSID of the algorithm.
Read/write property Available Indicates if the algorithm is currently available.
Read/write property DegreeOfFreedom Parameter value used to limit the area used to move the schematic nodes during each algorithm's iteration.
Read-only property Enabled Indicates if the algorithm is currently enabled.
Method Execute Execute the schematic algorithm.
Read/write property Label The label of the algorithm.
Read/write property NumberOfIterations Number of Force Directed schematic algorithm iterations executed before the final result is shown.
Read/write property Overridable Indicates if the algorithm properties page is editable from ArcMap; that is, enabling the Layout Properties button in ArcMap.
Read/write property PropertySet The property set of the algorithm contains a collection of its parameters and their values.
Read/write property RepelFactor Parameter value used to quickly increase the schematic nodes displacement for nodes that are very close.
Read/write property SchematicDiagramClassName The diagram class object used to initialize the algorithm.
Read-only property UseEndNode Indicates if the algorithm use end nodes.
Read-only property UseRootNode Indicates if the algorithm use root nodes.
Read/write property WithoutDegreeTwoNodes Indicates if the nodes with degree 2 can be temporally out-of-the-way during the first phase of the algorithm execution so the computing time is decreased.
