Special FME feature attributes are used to hold AutoCAD entity attributes. The AutoCAD writer uses these attribute values as it fills in an entity structure during output. The AutoCAD reader sets these attributes on the FME feature it creates for each entity it reads.
The AutoCAD Civil 3D Reader makes use of the same standard attributes as the AutoCAD DWG/DXF Reader. Please refer to the Autodesk AutoCAD DWG/DXF format documentation for additional information.
Attributes used related to Civil 3D specific entity types are described below. All attributes specific to Civil 3D entities are prefixed by aec_ rather than the standard CAD prefix of autocad_.
