About Setting Paths to Referenced Drawings

    About Setting Paths to Referenced Drawings

    You can view and edit the file name and path used when locating a particular drawing
    reference (xref). Use this option if the referenced file has been moved to a different
    folder or renamed since it was first attached.

    You can choose from three types of folder path information to save with an attached
    reference: a full path, a relative path, and no path.

    Specify a Full (Absolute) Path

    A full path is a fully specified hierarchy of folders that locates the file reference.
    A full path includes a local hard drive letter, a URL to a website, or a network server
    drive letter.

    Specify a Relative Path

    Relative paths are partially specified folder paths that assume the current drive
    letter or the folder of the host drawing. This is the most flexible option, and enables
    you to move a set of drawings from your current drive to a different drive that uses
    the same folder structure.

    If the file that is being referenced is located on a different local hard drive or
    on a network server, the relative path option is not available.

    The conventions for specifying a relative folder path are as follows:

    Look in the root folder of the host drawing’s drive


    From the folder of the host drawing, follow the specified path


    From the root folder, follow the specified path


    From the folder of the host drawing, follow the specified path


    From the folder of the host drawing, move up one folder level and follow the specified


    From the folder of the host drawing, move up two folder levels and follow the specified

    NOTE: If a drawing that contains referenced files is moved or saved to a different path,
    to a different local hard drive, or to a different network server, you must edit any
    relative paths to accommodate the host drawing’s new location or you must relocate
    the referenced files.

    Specify No Path

    When no path information is saved with the attached external reference, the following
    search is initiated in the order shown:

    • Current folder of the host drawing
    • Project search paths defined on the Files tab in the Options dialog box and in the
      PROJECTNAME system variable
    • Support search paths defined on the Files tab in the Options dialog box
    • Start In folder specified in the Microsoft آ® Windows آ® application shortcut

    Specifying the No Path option is useful when moving a set of drawings to a different
    folder hierarchy or to an unknown folder hierarchy.

    Know When a Referenced Drawing Has Been Relocated

    If the drawing you are working on contains an xref that has been moved to a different
    folder, a message is displayed at the site of the xref when you load the drawing.
    The message indicates that the xref cannot be loaded using the old path. When you
    specify the new path, the xref is reloaded into your drawing.

    Use Project Names to Define Referenced Drawing Paths

    Project names make it easier for you to manage xrefs when drawings are exchanged
    between customers or if you have different drive mappings to the same location on
    a server. The project name points to a section in the registry that can contain one
    or more search paths for each project name defined.

    If the program cannot find an xref at the location specified by the search path, the
    prefix (if any) is stripped from the path. If the drawing has a PROJECTNAME value
    set and a corresponding entry exists in the registry, the program searches for the
    file along the project search paths. If the xref still is not located, the program
    search path is searched again.

    You can add, remove, or modify the project names that exist in the registry. The folder
    search paths beneath the project name can also be added, removed, or modified.

    The search paths beneath the project name can be added, removed, or modified in the
    same manner as the project name. The order in which the folders are searched can also
    be modified. Projects and their search paths can only be edited through the Files
    tab in the Options dialog box. You cannot edit project names at the Command prompt.

    Once you have established a project name and the search paths you want associated
    with that project name, you can make that project name the currently active project.
    The program searches the paths associated with that currently active project for xrefs
    that were not found in the current folder of the host drawing, the full search path,
    the current drawing folder, or the program support paths.

    Change Reference Paths in Multiple Drawings (Advanced)

    When you relocate drawing files or the external files that they reference, including
    other drawing files, text fonts, images, and plot configurations, the reference paths
    that are saved in the drawing need to be updated. The Autodesk Reference Manager lists
    referenced files in selected drawings and provides tools to modify the saved reference
    paths without having to open each drawing file. You can also use Reference Manager
    to identify and fix unresolved references.

    Reference Manager is a stand-alone application with its own Help system. To access
    it, click Start menu (Windows) (All) Programs Autodesk AutoCAD Reference Manager. If you are working on a network, it may not have been installed
    on your computer.

    IMPORTANT: Reference Manager is intended primarily for CAD managers who thoroughly understand
    paths. It changes multiple paths at once, and you cannot undo your actions. Use extreme
    caution, especially if you are working on a network.
