MicroStation/J 07.01.05.03 Batch print/conversion to PDF

Dear Friends,

We have a requirement to convert/print large number of MicroStation/J files to PDF.

These are pipeline isometrics extracted from PDS 3D Model.

We can print one file at a time to PDF format.

However we do not know how to do batch print to PDF.

Please help.

Regards,

Girish
