ORD to Machine Control

Hello has anyone been able to or have a work process for exporting an ORD design to a machine control file? I use a Topcon tool called Magnet Data Convertor that can convert DGN to Topcon's TP3 format (Topcon's machine control format) At this time I believe the only process that works is by reading the file into Autodesk Civil 3D then exporting to TP3 via Magnet Data Convertor, is this correct or can I export directly from ORD? ORD also "should" to my understanding be able to publish a TP3 directly (without using Magnet Data Converter)
