IZ2 Interface

Provides access to additional members that identify geometric objects that can have 3D coordinates and defines operations on such objects.

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

This interface is new at ArcGIS 9.3. It supersedes IZ.

	Name	Description
	CalculateNonSimpleZs	Calculates the non-simple Z values by extrapolation/interpolation for polylines and interpolation for polygons.
	InterpolateFromSurface	Use the specified functional surface to generate Z values for the vertices of this object.
	InterpolateZsBetween	Generate Z values by linear interpolation for all vertices in the range [start+1, end-1].
	MultiplyZs	Multiplies all the Z values by a factor.
	OffsetZs	Offsets all the Z values by an offset value.
	SetConstantZ	Sets Z coordinates at all vertices to zLevel.
	SetNonSimpleZs	Replaces undefined (nonsimple) Z values with the specified constant value.
	ZMax	The maximum Z value.
	ZMin	The minimum Z value.
	ZVertical	Indicates if at least two consecutive vertices of this polyline or polygon have the same x and y values, but distinct z values.

Interfaces	Description
IZ	Provides access to members that identify geometric objects that can have 3D coordinates and defines operations on such objects.
IZCollection	Provides access to operations on Z-aware geometries.

Classes	Description
Polygon	A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes.
Polyline	An ordered collection of paths; optionally has measure, height and ID attributes.
