IConstructMultiPatch Interface

Provides access to members that can be used to construct MultiPatches.

Product Availability

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

Description

Constructs a MultiPatch by extruding a non-point based 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. Polygon geometry is assumed to be planar.

Members

		Description
	ConstructExtrude	Construct a MultiPatch by using an input (non-point) geometry as one base and offsetting the Zs already set on the input geometry to get the second base.
	ConstructExtrudeAbsolute	Construct a MultiPatch by extruding a (non-point) geometry using its initial Zs for one base, and a uniform input Z for the other.
	ConstructExtrudeAlongLine	Construct a MultiPatch by extruding a (non-point) geometry along a specified line, using the Zs on the two ends of the line to set Zs on the top and bottom.
	ConstructExtrudeBetween	Construct a MultiPatch by extruding a (non-point) geometry between two functional surfaces.
	ConstructExtrudeFromTo	Construct a MultiPatch by extruding a (non-point) geometry between two specified Z values.
	ConstructExtrudeRelative	Construct a MultiPatch by extruding a (non-point) geometry along a specified vector, using Zs already set on the input geometry.
