IPolyline6 Interface

Provides access to members that extend a polyline object.

Members

	Name	Description
	Densify	Converts this polycurve into a piecewise linear approximation of itself.
	Dimension	The topological dimension of this geometry.
	EnumShortestPath	Not implemented.
	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 This method is obsolete.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.
	IsSimpleNonPlanar	Returns false if zero length segments are detected (zero in 2 dimensions), parts at endpoints need to be merged, or need to reorient segments that are pointing against the prevailing orientation for a part.
	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.
	Reshape	Modifies this polyline by replacing some of its segments with some segments from reshapeSource.
	ReshapeEx	If bInterpolateReshaped is true, then new vertices will be interpolated based on vertices from the polyline being reshaped. Otherwise, attributes on the reshaping line will be preserved in the output.
	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.
	SimplifyEx	Use either planar or network simplify regardless of current attribute awareness.
	SimplifyNetwork	Removes zero length segments (zero in 2 dimensions), merges parts at endpoints that only connect to each other, reorients segments that are pointing against the prevailing orientation for a part.
	SimplifyNonPlanar	Removes zero length segments (zero in 2 dimensions), reorients segments that are pointing against the prevailing orientation for a part.
	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.
	SplitAtPoint	Introduces a new vertex into this polyline at the location on it closest to the input point.
	ToPoint	The 'to' point of the curve.
	TouchCut	Cut a polyline at locations where the cutter only touches the polyline, in addition to locations where the cutter crosses it.
	Weed	Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.

IPolyline6.IsSimpleNonPlanar Property

Returns false if zero length segments are detected (zero in 2 dimensions), parts at endpoints need to be merged, or need to reorient segments that are pointing against the prevailing orientation for a part.

Public Function get_IsSimpleNonPlanar ( _
    ByRef pReason As esriNonSimpleReasonEnum _
) As Boolean

public bool get_IsSimpleNonPlanar (
    ref esriNonSimpleReasonEnum pReason
);

Description

The return boolean value indicates whether or not the geometry is simple. If the return is false, the "reason" parameter can be inspected.

IPolyline6.SimplifyNonPlanar Method

Removes zero length segments (zero in 2 dimensions), reorients segments that are pointing against the prevailing orientation for a part.

Public Sub SimplifyNonPlanar ( _
)

public void SimplifyNonPlanar (
);

Description

SimplifyNonPlanar performs the following alterations to the base Polyline:

1) Deletes empty and zero length segments.2) Removes empty parts.3) Makes segment orientation mutually consistent. Ensures that the following FromPoints and preceding ToPoints of connected segments are equal.4) Creates new parts for discontiguous segments or segments with different attributes.5) For a pair of segments in a part that share an endpoint such that one segment has NaN attributes and the other has non-NaN attributes, assign the non-NaN attributes of one to the corresponding NaN slots of the other.

This method is the similar to SimplifyNetwork, except parts are not merged where an end point is shared.
