This command allows you to convert Autodesk Civil3D or Land
Desktop custom surface objects into standard AutoCAD entities. For
example, this command will convert AECC_CONTOUR objects into
polylines with elevation. The conversion is done by loading a .dwg
file, converting the custom objects and then saving as a new .dwg
file. The .dwg file to convert should not be currently opened. The
conversion routine was developed by the Open Design Alliance (ODA)
and does not use object enablers from Autodesk.
