OpenBridge Modeler

To Upgrade Existing DGN or DWG Files

To batch upgrade existing DGN or DWG files to the latest file format, use the following procedure.

Note: You do not need to convert single files in order to open them. Opening a file created in a previous version of OpenBridge Modeler will prompt you to convert with the option to create a backup copy.
  1. Select File > Tools > Batch Process. The Batch Process dialog opens.
  2. Select the (Add Files or Directories to Process) tool. The Select Files and Directories to process dialog opens.
  3. Select any number of existing OpenBridge Modeler DGN and DWG files and then click Done.
    Note: You can drag files from Windows Explorer or models from Explorer into the Process Tasks list in the Batch Process dialog. Similarly, you can drag models into the list box from the Models dialog of the current session, or another open session of OpenBridge Modeler.
  4. Select the Initial Model to use.
    Note: When processing DGN or DWG files, either the All Models or Default Model Only option can be used to process default models or all models and layouts within DGN and DWG files.
  5. Select any number of the DGN and DWG from the Process Tasks list.
  6. Click the (Process Batch Process Job) tool.
All converted files are saved at their original location and a backup copy of the original is saved at the location specified by the MS_BACKUP variable along with a process report batchprocess.log.
Tip: You can edit the MS_BACKUP from the Configuration Variables dialog by selecting File > Settings > Configuration. When the variable or path is missing, the backup is created at the source location with an automatic rename.
Important: Prior to converting large models with large number of groups, the MS_DWG_MAX_DICTIONARYITEMS variable should be set to 50000 or more, otherwise groups will not covert. By default it is set to 2000 entries.
