An overview of the Conversion toolset

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 Feature Class

Geoprocessing ToolDescription

Feature Class Z To ASCII

Exports 3D features to ASCII text files storing GENERATE, XYZ, or profile data.

Multipatch Footprint

Creates polygon footprints representing the two-dimensional area of multipatch features.

From File

Geoprocessing ToolDescription

ASCII 3D To Feature Class

Imports 3D features from one or more ASCII files stored in XYZ, XYZI, or GENERATE formats into a new feature class.

Import 3D Files

Imports one or more 3D models into a multipatch feature class.


This tool imports one or more triangulated irregular network (TIN) surfaces from a LandXML file to output Esri TINs.

LAS To Multipoint

Creates multipoint features using one or more lidar files.

Point File Information

Generates statistical information about one or more point files in a polygon or multipatch output.

From LAS Dataset

Geoprocessing ToolDescription

LAS Dataset To TIN

Exports a triangulated irregular network (TIN) from a LAS dataset.

From Raster

Geoprocessing ToolDescription

Raster Domain

Constructs a 3D polygon or polyline delineating the height along the boundary of a raster surface.

Raster To Multipoint

Converts raster cell centers into 3D multipoint features whose Z values reflect the raster cell value.

Raster To TIN

Converts a raster to a triangulated irregular network (TIN) dataset.

From Terrain

Geoprocessing ToolDescription

Terrain To Points

Converts a terrain dataset into a new point or multipoint feature class.

Terrain To Raster

Interpolates a raster using z-values from a terrain dataset.

Terrain To TIN

Converts a terrain dataset to a triangulated irregular network (TIN) dataset.

From TIN

Geoprocessing ToolDescription

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

Interpolates a raster using z-values from the input TIN.

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.
