    Is this normal behaviour?? Reply
    So I have a basic schematic, then produced a board from it. For some reason and with both windows open and the board routed, when I do a simple thing like move a component on the board, orcad physically deletes files in my project tree/folder, the .DSN file is defiantly deleted I’m sure there are others. So now I have to restore a backup from my works server.

    Why would it do this? Surely this is not normal behaviour?? I’ve also noticed it doing the same thing when I select my entire design and delete the tracks. Im new to orcad pcb editor so its highly possible its just me doing something weird.

    in fact, the .dsn file is deleted during the routing of the board. so i no no longer have a schematic!

    I can see this occurring if the OrCAD Schematic and the Allegro database reside in the same directory with the same file prefix.   When you run the router it writes a .DSN file of the Allegro database which could overwrite the OrCAD Schematic .DSN due to it being the same prefix.

    If you did have the Allegro Database in the same directory as the OrCAD Schematic that's what may of happened.

    Hope this helps,

    Hi and thanks for the response, I called the tech support guys at parallel systems and sent in my project. They also very quickly were able to diagnose the same thing... Not sure how I managed to force it in to saving the brd in the root, and not the allegro sub dir.
