    Default Invalid File?

    Registered forum members do not see this ad.

    Hy everyone,

    I have a file I need to open for work, a.dwg specifically, and my CAD says that it is an invalid file. Could this be because I am running 2005 and this may be newer? Any ideas would be greatly appreciated.

    It is more than likley that when the file you are trying to open was saved it was saved in a latter version of AutoCAD than 2005.

    Ask the person who sent you the file to backsave the file, then resend. Or post it on heer and i or some one will backdate it for you.

    Hopefully this will help.

    Try to open it in notepad.
    Then open a file that you know works in notepad as well and check that they are similar. you will be able to tell after the first line as the first charcters will be something like AC1021 if it is a true dwg.

    Did you receive this file by email or some other source?
    It could be that it has become corrupt, or actually had its extension changes from something else, say a pdf or something.

    Eastside,
    you can download a free veiwer from autodesk called
    DWG TrueView 2009 that will allow you to open up any dwg/dxf
    file from any other version and save it to your version.
    You can find it on AutoDesks website.
    Never trust a computer you can't throw out a window!
