NOTE: This environment is only applicable to ArcGIS 9.2, or higher.
Specify the Z tolerance that will be used for processing and set to the output geodataset.

Usage tips
- If the output is a feature class inside a feature dataset, the environment will be ignored because all feature classes inside a feature dataset must have the same Z tolerance.
- If the output is a standalone feature class, raster catalog or feature dataset, the tolerance of the input will be used as the processing and set as the output feature class' Z tolerance. For tools that have multiple inputs (Intersect for example), the tolerance of the first input in the list will be used as the default. To override these defaults, set the Z tolerance environment to the desired value.
- If the geoprocessing tool does not have an input geodataset (for example, Create Feature Class, Create Feature Dataset, and Create Raster Catalog) and if the environment is left blank, the default Z tolerance is set to 0.001 units. To override this default, set the environment to the desired value.
- If the tolerance is set to "Unknown" units, the units are assumed to be the same as the output vertical coordinate system's units.
- If the Z tolerance is not at least twice as large as the Z resolution value, the Z tolerance is set to be twice as large as the Z resolution by default.
- Tolerance will not be persisted to a dataset in a pre-92 geodatabase.
