Importing CAD data into ArcGIS

ArcGIS can import CAD data in .dwg, .dxf, and .dgn formats. Most importing is done through the ArcToolbox, which can be opened in ArcCatalog or ArcMap using the Toolbox button ArcToolbox Button.

The Import from CAD tool, under Conversion Tools > To Geodatabase can import a collection of CAD files and convert them into feature classes for use in ArcGIS.

Tip: To find a tool in the toolbox by name, use the Index or Search tabs at the bottom of the toolbox panel.

To import individual CAD feature classes, the class needs to be projected to the coordinate system that the GIS data is using. To do so, use the Project tool, under Data Management Tools > Projections and Transformations > Feature. The tool will ask you to select the file you want to input, the location to output the converted feature class, and the new coordinate system to use.

If the original feature class is already in correct coordinates, the Feature Class to Feature Class or Feature Class to Geodatabase tools, under Conversion Tools > To Geodatabase can be used to quickly pull the original classes into ArcGIS.
