ICurve2 Interface (ArcObjects .NET 10.6 SDK)

Provides access to members that extend the functionality of one dimensional curves. **Note:** the ICurve2 interface has been superseded byICurve3. Please consider using the more recent version.

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

ICurve2 extends Segment functionality to allow both endpoints to be set simultaneously. This allows the segment parameterization to be maintained when relocating both the From Point and the To Point.

Name |
Description | |
---|---|---|

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. | |

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 This method is obsolete.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. | |

PutCoordsEx | Sets this segment's endpoints to 'from' and 'to'. | |

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. | |

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. | |

ToPoint | The 'to' point of the curve. |

Interfaces | Description |
---|---|

ICurve | Provides access to properties and methods of all 1 dimensional curves (polylines, segments, boundaries of polygons, etc.). |

IGeometry | Provides access to members that describe properties and behavior of all geometric objects. |

CoClasses and Classes | Description |
---|---|

BezierCurve | A cubic Bezier curve defined between two points; optionally has measure, height and ID attributes at each endpoint. |

CircularArc | A portion of a circle that connects two points optionally has measure, height and ID attributes at each endpoint. |

EllipticArc | A portion of the boundary of a 2D ellipse that connects two points; optionally has measure, height and ID attributes at each endpoint. |

Line | A 2D straight line between a pair of 2D endpoints; can optionally have height, measure and ID attributes at each endpoint. |

Polyline | An ordered collection of paths; optionally has measure, height and ID attributes. |
