	CountParts	Gets the number of parts contained in the Multipart. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	GeometryType	Overridden. Gets the geometry type. Always returns GeometryType.Polyline.
	Handle	Gets the opaque handle to the underlying native object. (Inherited from ArcGIS.Core.CoreObjectsBase)
	HasID	Gets or sets the HasID flag of the instance. (Inherited from ArcGIS.Core.Geometry.GeometryBuilder<Polyline>)
	HasM	Gets or sets the HasM flag of the instance. This indicates whether the geometry contains Ms. (Inherited from ArcGIS.Core.Geometry.GeometryBuilder<Polyline>)
	HasZ	Gets or sets the HasZ flag of the instance. This indicates whether the geometry contains Zs. (Inherited from ArcGIS.Core.Geometry.GeometryBuilder<Polyline>)
	IsEmpty	Gets if the instance is an empty geometry. (Inherited from ArcGIS.Core.Geometry.GeometryBuilder<Polyline>)
	SpatialReference	Gets or sets the SpatialReference for the geometry being built. (Inherited from ArcGIS.Core.Geometry.GeometryBuilder<Polyline>)

	Name	Description
	AddPart	Overloaded. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	AddParts	Adds the parts constructed from the set of enumeration of line segments to the MultipartBuilder. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	AddSegment	Overloaded. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	Clone	Returns a clone of the builder. This method must be called on the MCT. Use QueuedTask.Run.
	CountSegments	Gets the count of segments for the specified part. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	CreatePolyline	Overloaded.
	Dispose	(Inherited from ArcGIS.Core.CoreObjectsBase)
	FromEsriShape	Creates a new instance of a Polyline class from an Esri shape buffer.
	FromJson	Creates a new instance of a Polyline class from a JSON string representation.
	FromXML	Creates a new instance of a Polyline class from an XML string representation.
	GetSegmentBuilder	Get a SegmentBuilder for the segment at the specified index on the specified part of the MultipartBuilder. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	InsertPart	Overloaded. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	InsertParts	Insert the parts constructed from the set of enumeration of line segments to the MultipartBuilder before the specified index. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	InsertSegment	Overloaded. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	QueryClothoidParameters	Queries parameters to be used when creating an instance Polyline or PolylineBuilder class that is a linear approximation to a clothoid. This method must be called on the MCT. Use QueuedTask.Run.
	RemovePart	Remove the part specified by partIndex. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	RemoveSegment	Remove the segment at the specified index from the part specified by partIndex. There is no return value. This method must be called on the MCT. Use QueuedTask.Run. Note: a value of partIndex=-1, segmentIndex=-1 removes the last segment from the last part of the multipart. All other combinations should be self-explanatory. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	ReverseOrientation	Changes the direction of the MultipartBuilder parts without changing the spatial position of the parts. The From Point and To Point of each Segment in each part of the MultipartBuilder are interchanged. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	SetEmpty	Sets the geometry of this builder to empty. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.GeometryBuilder<Polyline>)
	SplitAtDistance	Introduces a new vertex into the last part of this polyline at a specified distance from the beginning of the polyline. For a split to happen, the split distance must be between the From and To points of the polycurve. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	SplitPartAtDistance	Introduces a new vertex point to the part specified by partIndex at a specified distance from the From point of the curve. For a split to happen, the split distance must be between the From and To points of the part. This method must be called on the MCT. Use QueuedTask.Run. (Inherited from ArcGIS.Core.Geometry.MultipartBuilder<Polyline>)
	ToGeometry	Overridden. Returns a Polyline instance representing the current state of the builder. This method must be called on the MCT. Use QueuedTask.Run.
