Mstn allows users to open pdfs directly. Also supports pdfs as Ref attachments. This is very useful. However, the pdf is opened in Mstn in read-only mode. The user will need to save as dgn and edit before printing the new content as a pdf.
It would be great if the pdf printing info like paper size, print extents and other metadata can be preserved when converting to .dgn. This would allow the user to use Mstn as a pdf editor for marking up and commenting w/o having a separate editor like Bluebeam or pdf-Xchange.
