Tools that honor the TIN Storage Version setting will output TIN surfaces in the specified version.
- When constructing TIN surfaces in versions of ArcGIS prior to 10, make sure to set this environment setting to PRE_10.0.
- CURRENT—Can be either conforming Delaunay triangulation or constrained Delaunay triangulation. This option also adds support for additional spatial references. This is the default.
- PRE_10.0—Supports Delaunay conforming triangulations for constructing TINs.
