Remove Feature Class From Terrain (3D Analyst)

Available with 3D Analyst license.

Summary

Removes reference to a feature class participating in a terrain dataset.

Usage

• This tool will only delete embedded features referenced by a terrain dataset.

• The terrain may need to be rebuilt using Build Terrain if the features being removed were referenced as masspoints surface type. Both the terrain dataset's Properties dialog box in ArcCatalog and the terrain layer's Properties dialog box provide an indication as to whether the dataset needs to be rebuilt.

• When used in an SDE database, the input terrain cannot be registered as versioned.
