Enumerations

EAuditResults	Enumerates the result types of an audit.
ECreateOptions	Enumerates the options for creating a topology.
EOpenMode	Enumerates the ways to open a topology model.
EStatus	Enumerates the status types of a topology model.

Methods

~AcMapTopology	Destroys an instance of this class.
AcMapTopology	Constructs an instance of this class.
AddCurveObject	Adds a curve (linear object) to this topology model.
AddPointObject	Adds a point to this topology model.
AddPolygons	Adds objects to a polygon topology model.
Buffer	Creates a new topology with the specified buffer setting on the current topology model. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
Clip	Uses the overlay polygon topology as a boundary to clip and discard the parts of the source polygons outside the overlay polygons. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
Close	Closes this topology model.
Create	Creates a topology. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings(). If caller does not call these functions, then node creation defaults to false, missing-centroid creation defaults to true, and the node or centroid block name defaults to ACAD_POINT.
Create	Creates a topology - this function is not yet implemented in AutoCAD Map; use the other Create()function.
DeleteEdge	Deletes an edge from this topology model.
DeleteNode	Deletes a node from this topology model.
DeleteNode	Deletes a node from this topology model.
DeletePolygon	Deletes a polygon from the current topology model.
DeletePolygon	Deletes a polygon from the current topology model.
Dissolve	Combines entities that share the same data value in a specified column.
Erase	Uses the overlay polygon topology as a mask to erase everything in the source polygon topology that is covered by the overlay topology. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
FindEdge	Finds the edge closest to a specified point.
FindEdge	Finds the edge with the specified ID.
FindNeighborPolygons	Finds all polygons that are neighbors of those edges that are based on a specified curve.
FindNode	Finds the node nearest a specified point.
FindPolygon	Finds the smallest polygon containing a specified point.
FindTopologyObject	Finds the object (node, full edge, or polygon) nearest a specified point within a specified tolerance.
GetBackwardEdge	Retrieves the half edge with the specified object ID from this topology model.
GetDescription	Retrieves the description of this topology model.
GetEntityId	Retrieves the object ID of the AutoCAD entity associated with the specified topology element ID in the current drawing or source drawing.
GetEntityIds	Retrieves the object IDs of all the AutoCAD entities associated with the topology elements in the current drawing.
GetForwardEdge	Retrieves the half edge with the specified object ID from this topology model.
GetFullEdge	Retrieves the full edge with the specified object ID from this topology model.
GetFullEdges	Retrieves all full edges from this topology model.
GetMarkerStyles	Retrieves the pointer to the error-marker settings of this topology model.
GetName	Retrieves the name of this topology model.
GetNode	Retrieves the node with the specified object ID from this topology model.
GetNodes	Retrieves all nodes from this topology model.
GetPolygon	Retrieves the polygon with the specified object ID from this topology model.
GetPolygons	Retrieves all polygons from this topology model.
GetStatus	Retrieves the status of this topology model.
GetType	Retrieves the type of this topology model.
Identity	Performs a Union() on the source topology and an Intersect() on the overlay topology. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
Intersect	Combines topologies and keeps only the common geometry. Intersect acts like the Boolean AND operation. The results are the same no matter the order topologies are chosen. Object data are combined for the two operations. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
IsComplete	Determines whether this topology model is complete.
IsFixedType	Determines whether this topology model can contain only elements of its own type.
IsLinearType	Determines whether this topology model is a network topology.
IsLogicalType	Determines whether the elements in this topology model can be connected if their graphical representations are farther apart than the tolerance value.
IsPointType	Determines whether this topology model is a point topology.
IsPolygonType	Determines whether this topology model is a polygon topology.
MergePolygons	Merges neighboring polygons, dissolving the boundaries between them.
MergePolygons	Merges neighboring polygons, dissolving the boundaries between them.
MergePolygons	Merges two neighboring polygons, dissolving the boundaries between them.
MergePolygons	Merges two neighboring polygons, dissolving the boundaries between them.
MoveNode	Moves a node to the new position.
MoveNode	Moves a node to the new position.
NeedsRefresh	Determines whether this topology model is correct.
Open	Opens the topology model in only the current drawing. After you are finished with a topology model, call Close()to close it.
Open	Opens the topology model in both current and source (attached) drawings. After you are finished with a topology model, call Close()to close it.
Paste	Pastes the overlay polygon topology on top of the source polygons. The source polygons not covered by the overlay remain. Paste can be used with only polygons. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
Refresh	Updates a topology element.
SetCentroidCreationSettings	Sets the centroid-creation parameters of this topology model.
SetDescription	Sets the description of this topology model.
SetEdgeCreationSettings	Sets the edge-creation parameters of this topology model.
SetNodeCreationSettings	Sets the node-creation parameters of this topology model.
ShowGeometry	Highlights the topology model with the specified color.
SplitPolygon	Splits a polygon along a curve.
SplitPolygon	Splits a polygon along a curve.
TraceBestPath	Finds the least-cost path between start and end points with intermediate points to visit.
TraceFlood	Traces the flood from a specified point.
TraceLeastCostPath	Finds the least-cost path between two points.
Union	Combines polygons with polygons and keeps all geometry. Union acts like the Boolean OR operation and can be used with only polygons. To set topology-creation values, call the three functions SetNodeCreationSettings(), SetEdgeCreationSettings(), and SetCentroidCreationSettings().
