How to retain Title Block data/information when separate DWG & DGN sheets are exported from Promis.e and imported into MicroStation?

Dear Sirs,

We are required by one of our Customers to supply them with DGN and DWG copies of the Electrical Schematics we have designed for their Project.

The issue they are having is once the Schematics have been exported into either DWG's or DGN's the Title Block becomes non-conformant due to the attributes being exploded (or appear to be exploded). Microstation doesn't allow them to import the Project file (.prj).

It's important that our Customer gets the attributes contained within the drawing as they are converted into metadata when imported into ProjectWise.

Would you be kind enough to either advise on the issue or explain the process of exporting and importing the title block and what we need to do to achieve an output which retains the attributes please?

Kind Regards, Dave.
