#### Product Availability

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

#### Members

Description |
||
---|---|---|

AddPoint | Adds a vertex to a Path, Ring, Polyline, or Polygon; or adds a reference to the input point to a Multipoint, TriangleFan, or TriangleStrip. | |

AddPointCollection | Adds copies of points in the input point collection to this Path, Ring, Polyline, or Polygon; or adds references to the points in the collection to this Multipoint, TriangleFan, or TriangleStrip. | |

AddWKSPointVA | Adds vertices/points. | |

AddWKSPointZs | Adds vertices/points to this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch. | |

EnumVertices | A new enumerator for this point collection. | |

IndexedEnumVertices | An indexed vertex enumerator for this point collection. | |

InsertPointCollection | Inserts copies of points, from the input point collection, as vertices into this Path, Ring, Polyline, or Polygon; or references to points in the input point collection into this Multipoint, TriangleFan, or TriangleStrip. | |

InsertWKSPointVA | Inserts new vertices/points. | |

InsertWKSPointZs | Inserts new vertices/points into this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch. | |

Point | A copy of the ith vertex of a Path, Ring, Polyline, or Polygon; or a reference to the ith point of a Multipoint, TriangleFan, or TriangleStrip. | |

PointCount | The number of points in the collection. | |

QueryPoint | Queries for a point in the PointCollection at given index. | |

QueryWKSPointVA | Copies vertices/points coordinates to the array of point structures. | |

QueryWKSPointZs | Copies vertices/points coordinates to the array of point structures. | |

RemovePoints | Removes vertices from a Path, Ring, Polyline, or Polygon, or references to points from a Multipoint, TriangleFan, or TriangleStrip. | |

ReplacePointCollection | Replaces vertices/points within a PointCollection. | |

ReplacePoints | Replaces vertices/points within a PointCollection. | |

SetPointCollection | Replaces all vertices of this Path, Ring, Polyline, or Polygon with copies of the points in the input collection; or all points of this Multipoint, TriangleFan, or TriangleStrip with references to points from the input collection. | |

SetWKSPointVA | Replaces all vertices/points. | |

SetWKSPointZs | Replaces all vertices/points of this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch with new ones. | |

UpdatePoint | Changes the ith vertex or point to be a copy of the input point. |
