ArcObjects Library Reference (Geometry)

IPolycurve3 Interface

Provides access to members that extend IPolycurve with additional splitting and densification methods.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

	Name	Description
	Densify	Converts this polycurve into a piecewise linear approximation of itself.
	DensifyByAngle	Converts this polycurve into a piecewise linear approximation of itself. Vertices are introduced at points where the included angle between tangents at those point is maxAngleDeviation.
	DensifyByAngleEx
	DensifyEx
	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	FromPoint	The 'from' point of the curve.
	Generalize	Generalizes this polycurve using the Douglas-Peucker algorithm.
	GeometryType	The type of this geometry.
	GeoNormalize	Shifts longitudes, if need be, into a continuous range of 360 degrees.
	GeoNormalizeFromLongitude	Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.
	GetSubcurve	Extracts a portion of this curve into a new curve.
	IsClosed	Indicates if 'from' and 'to' points (of each part) are identical.
	IsEmpty	Indicates whether this geometry contains any points.
	Length	The length of the curve.
	Project	Projects this geometry into a new spatial reference.
	QueryEnvelope	Copies this geometry's envelope properties into the specified envelope.
	QueryFromPoint	Copies this curve's 'from' point to the input point.
	QueryNormal	Constructs a line normal to a curve from a point at a specified distance along the curve.
	QueryPoint	Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve.
	QueryPointAndDistance	Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items.
	QueryTangent	Constructs a line tangent to a curve from a point at a specified distance along the curve.
	QueryToPoint	Copies the curve's 'to' point into the input point.
	ReverseOrientation	Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).
	SetEmpty	Removes all points from this geometry.
	Smooth	Converts this curve into a smooth curve containing only Bezier curve segments.
	SnapToSpatialReference	Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.
	SpatialReference	The spatial reference associated with this geometry.
	SplitAtDistance	Introduces a new vertex into this polyline at a specified distance from the beginning of the polyline.
	SplitAtDistances	Introduces new vertices into this polyline at specified distances from the beginning of the polyline.
	SplitAtPoint	Introduces a new vertex into this polyline at the location on it closest to the input point.
	SplitAtPoints	Introduces new vertices into this polyline at the locations on it closest to the input points. Do not consider points farther than cutoffDistance from the polyline.
	ToPoint	The 'to' point of the curve.
	Weed	Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.
