An overview of the Conversion toolset—Help

Available with 3D Analyst license.

The Conversion toolset provides a wide range of tools for converting various data types, including 3D features, rasters, terrains, TINs, and LAS datasets. 3D models can be imported to a multipatch and used in three-dimensional rendering in ArcScene or ArcGlobe. TIN surfaces can be imported from LandXML files, 3D features can be exported to ASCII files, and lidar data can be imported to a multipoint dataset. Converting between raster and TIN formats allows you to employ the benefits of each while modeling the same surface. For example, use a TIN to model a surface if you have features, such as lines or polygons, that should enforce natural features, such as ridges or valleys. Convert the TIN to a raster using the natural neighbors interpolation option to preserve the linear features and use spatial operators.

From TIN

Geoprocessing Tool	Description
TIN Domain	Creates a line or polygon feature class representing the interpolation zone of a triangulated irregular network (TIN) dataset.
TIN Edge	Creates 3D line features using the triangle edges of a triangulated irregular network (TIN) dataset.
TIN Line	Exports breaklines from a triangulated irregular network (TIN) dataset to a 3D line feature class.
TIN Node	Exports the nodes of a triangulated irregular network (TIN) dataset to a point feature class.
TIN Polygon Tag	Creates polygon features using tag values in a triangulated irregular network (TIN) dataset.
TIN to Raster	Creates a raster by interpolating its cell values from the elevation of the input TIN at the specified sampling distance.
TIN Triangle	Exports triangle faces from a TIN dataset to polygon features and provides slope, aspect, and optional attributes of hillshade and tag values for each triangle.
