I often have batch print files with dozens of DGNs listted. It is very frustrating for a batch file to fail for instance at 68/70 DGN plotted, especially with limited output where the error is. This could be cause be a DGN file name being renamed or moved, or a sheet model within a DGN being renames, deleted, etc.
I would request that there be an option to "Skip Files with Errors". When the batch completes, it should give a notice of all the errors/missing files/missing models.
Moving this to MicroStation ideas as the MicroStation team would be responsible for evaluation and implementation.
