Z Tolerance (Environment setting)
Tools that honor the Z Tolerance environment will override the default z-tolerance on geodatasets created in a geodatabase.
For a description of the default z-tolerance, see the following topic: Spatial reference and geoprocessing.
Usage notes
This environment setting will be ignored if the output is within a geodatabase feature dataset.
For tools such as Create Feature Class, Create Feature Dataset, and Create Raster Catalog, the default z-tolerance for the output geodataset is 0.001 meters (1 millimeter) or its equivalent in the vertical coordinate units.
If the tolerance units are not set or are set to UNKNOWN, the units are assumed to be the same as those of the output vertical coordinate system.
If the z-tolerance is less than twice the output geodataset's z-resolution value, a z-tolerance of two times the z-resolution will be used.
The z-tolerance is not preserved in geodatabase versions earlier than 9.2.
