IPolyline6 Interface

Provides access to members that extend a polyline object.

Members

Name Description
Method Densify Converts this polycurve into a piecewise linear approximation of itself.
Read-only property Dimension The topological dimension of this geometry.
Read-only property EnumShortestPath Not implemented.
Read-only property Envelope Creates a copy of this geometry's envelope and returns it.
Read/write property FromPoint The 'from' point of the curve.
Method Generalize Generalizes this polycurve using the Douglas-Peucker algorithm.
Read-only property GeometryType The type of this geometry.
Method GeoNormalize Shifts longitudes, if need be, into a continuous range of 360 degrees.
Method GeoNormalizeFromLongitude Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.
Method GetSubcurve Extracts a portion of this curve into a new curve.
Read-only property IsClosed Indicates if 'from' and 'to' points (of each part) are identical.
Read-only property IsEmpty Indicates whether this geometry contains any points.
Read-only property 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.
Read-only property Length The length of the curve.
Method Project Projects this geometry into a new spatial reference.
Method QueryEnvelope Copies this geometry's envelope properties into the specified envelope.
Method QueryFromPoint Copies this curve's 'from' point to the input point.
Method QueryNormal Constructs a line normal to a curve from a point at a specified distance along the curve.
Method QueryPoint Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve.
Method QueryPointAndDistance Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items.
Method QueryTangent Constructs a line tangent to a curve from a point at a specified distance along the curve.
Method QueryToPoint Copies the curve's 'to' point into the input point.
Method Reshape Modifies this polyline by replacing some of its segments with some segments from reshapeSource.
Method 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.
Method ReverseOrientation Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).
Method SetEmpty Removes all points from this geometry.
Method SimplifyEx Use either planar or network simplify regardless of current attribute awareness.
Method 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.
Method SimplifyNonPlanar Removes zero length segments (zero in 2 dimensions), reorients segments that are pointing against the prevailing orientation for a part.
Method Smooth Converts this curve into a smooth curve containing only Bezier curve segments.
Method SnapToSpatialReference Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.
Read/write property SpatialReference The spatial reference associated with this geometry.
Method SplitAtDistance Introduces a new vertex into this polyline at a specified distance from the beginning of the polyline.
Method SplitAtPoint Introduces a new vertex into this polyline at the location on it closest to the input point.
Read/write property ToPoint The 'to' point of the curve.
Method TouchCut Cut a polyline at locations where the cutter only touches the polyline, in addition to locations where the cutter crosses it.
Method 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.
