How to display the DGN file name that corresponds to the project page on the title block?
Currently, there is no title block variable for the file name. This article describes how to display the file name by inserting a text field, which is a feature of MicroStation.
Thanks to Michael Elwell for this tip.
Use the procedure described in the Set DGN files to update fields automatically article on existing pages that use the title block and seed files. If that procedure is not done, the file name field added to the title block will only update manually (Tools > Text > Update All Fields).
Test a modified seed file by creating a new page. On the New Page dialog, specify an Initial Mode that uses the modified seed file, and specify the Title Block to which the File Name field was added. When the page is first created, the file name will not be updated. Close and reopen the page and it should show the correct file name.
Fields are identified by their gray background color. This color is not displayed on printed output. To hide the background color on the screen, set the Hide Field Background check box on Workspace > Preferences > Text.
An alternative to using a text field is to use pen tables, but that method only displays the file name on printed output.
