IZCollection Interface

Provides access to operations on Z-aware geometries.

Product Availability

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

Description

IZCollection supports operations performed on a collection of geometry objects that have Z values. For IZCollection operations to be performed, the object must be ZAware and have non-NaN Zs.

When To Use

If you are using a development language that does not support C style arrays, use IGeometryBridge instead. The IGeometryBridge interface solves that problem allowing you to pass safe arrays instead.
