Provides access to members that can be used to take a geometry and connect it to a translated version of itself to generate a higher-dimensional geometry.
**Note:** the IExtrude interface has been superseded by IExtrude2. Please consider using the more recent version.

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

Constructs a MultiPatch or Polyline by extruding a base geometry. Extrusion adds another dimension to the base geometry. Generally, this dimension is along the Z-Axis, but some extrusions allow the axis of extrusion to be defined by an input Line or Vector3D. Depending on the extrusion method, the base geometry may be preserved or may by projected to the XY-Plane and then extruded. Polylines, Polygons, and Envelopes can be extruded to produce MultiPatches. Points and Multipoints are extruded into Polylines. Polygon geometry is assumed to be planar. All input geometries should be topologically KnownSimple (Calling either IsSimple or Simplify makes the IsSimple state known to the geometry). If an input Polygon is not topologically simple, it will be simplified.

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

Extrude | Extrude using an input geometry as one base and offsetting the Zs already set on the input geometry to get the second base. | |

ExtrudeAbsolute | Extrude a geometry using its initial Zs for one base, and a uniform input Z for the other. | |

ExtrudeAlongLine | Extrude a geometry along a specified line, using the Zs on the two ends of the line to set Zs on the top and bottom. | |

ExtrudeBetween | Extrude a geometry between two functional surfaces. | |

ExtrudeFromTo | Extrude a geometry between two specified Z values. | |

ExtrudeRelative | Extrude a geometry along a specified vector, using Zs already set on the input geometry. |

GeometryEnvironment | Provides a way of creating geometries from different inputs and setting/getting global variables for controlling behavior of geometry methods. |

Extrusion on Polylines, Polygons, and Envelopes is the same as the extrusion performed by IConstructMultiPatch.
