Direct-read support of AutoCAD Civil 3D objects extends the support of standard AutoCAD .dwg files. Additional CAD feature classes are generated from Autodesk Civil 3D objects included in the drawing file. Many of these feature classes, when added to a map or scene, are rendered with enhanced symbology to mimic their symbology in the Autodesk Civil 3D. Each resulting feature from these AutoCAD Civil 3D objects includes design data properties that are included as feature attributes. These feature attributes include AutoCAD graphic properties, various AEC entity properties, and user-defined property sets.
