I work in both AutoCAD and Microstation and sometimes I need to convert my AutoCAD dwg to a Microstation dgn for various reasons.
AutoCAD has an export feature that allows you to select multiple file types. When selecting a Microstation file type, you are then prompted with the “Export DGN Settings” dialog box
Where you now have to select the proper seed file in order for dgn to convert. Sometimes finding where your company keeps these can be a daunting task. And even if you know where the seed files are stored, it still may not work properly.
My solution to this is quite simple and super easy!
Save the dwg file you want to covert to AutoCAD 2010 Format
