Use the Export to SDF command to export AutoCAD Civil 3D data to Spatial Data Format (SDF) files.
Spatial data format files can be used in AutoCAD Map 3D. The alignment, point, parcel, and pipe network data are converted to data objects with attributes.
The AutoCAD Civil 3D alignment, point, parcel, and pipe network data is converted to data objects with attributes. SDF files store data as features, which means that you are dealing with real-world objects rather than geometry.
