We have had very good success for converting .mi files directly to .dwg, .dxf, .cgm or .pdf files. The software is Imagenation by Spicer. However, in the recent time, Spicer was aquired by OpenText. Under the file formats it can read both ME10 .mi files and compressed .mi files.
The software comes with a Batch File Manager. Amazingly in the version we have, the batch conversion from one CAD 2D output to another 2D formation is nearly WYSIWYG or 99% identical coming from an .mi file of ME10 or CoCreate Annotation.
