Using the Batch Converter
The Batch Converter utility converts individual files, or entire directories of files, from any of the CAD file formats supported by MicroStation to any other supported format.
When you use the Batch Converter, you can set up a series of individual file conversions, and save them to a batch conversion job file. Later, you can open the job file and rerun the conversion using the previously set job values. The batch job updates only the files that have changed since the last time the job was run.
