Reference Manager. Post 15 in series “AutoCAD Cleanup”

Using Reference Manager to re-link data set.

Scenario: You received a set of files on CD. The folder structure conforms to your company standard, but when you open plot files, XREFs are not found. You need to re-link all XREFs.

refman1

  • Copy the CD contents to a local drive and examine its folder structure.
  • Start by figuring out which files are intended to be the plot-able sheet files. This is the hardest part. You can use the transmittals, printouts, thumbnail images and/or any other means at your disposal. Sometimes you can guess from the folder structure or the file name. In this example it looks like all the plot sheets should be in a discipline specific subfolder of the plot folder.
  • Once you have a working assumption of which files are the plot sheets, you can begin solving the puzzle. Start Reference Manager.

refman2

  • Add the sheet files to be analyzed. I always work in batches based on plot file locations. You will be asked if you want to add all XREFs that are attached to the drawings being added. If you select “Yes”, then all nested XREFs will be added, and it can get large and confusing very quickly. In addition, you can also encounter circular referencing. When dealing with large sets, it is easier to process one level of nesting at a time by answering “No” and adding XREFs for processing later.

refman3

  • The Reference Manager interface has two views.

refman4

  • First, view the List by Drawing view to find out if any drawings are “broken”. In List by Drawing view, the left pane shows a hierarchical data structure with all resource files listed per drawing. If any of the XREFs or other resources are not found the drawing icon is crossed by a red line. In the right pane you can see all the needed resources. You can sort them any way you want. (by type, status, saved path, found path or any other column).

refman5

  • Now let’s attempt to repair all broken links. Change to the List by Reference Type view. Select XREFs in the left pane. Sort the right pane by status.

refman6

  • The missing XREFs saved path points to the P: drive. But your refman7system does not have a P: drive. To remedy this situation and make your data set portable, you need to convert the full path to a relative path. Looking at the folder structure and saved path you can guesstimate that the XREFs should be in the discipline specific folder under the ref folder.
  • The path is relative to the location of the parent (host) file. But in this batch all plot files reside in the same folder. Select all XREFs with identical saved path. Click on Edit Selected Paths, and then change the path. To get from the location of the host file to the location of the XREFs, you need to go two levels up the folder tree, then go down to the \ref\arch folder.

refman9

  • You guessed right, and the status of the XREFs changed to refman10Resolved with a pencil logo (pencil-in feature) indicating that the change is not yet applied. Click on Apply Changes to write the new paths into the host files. The status changes to Resolved.
  • Process the rest of the files in groups based on the location of the host file and saved paths. If the path is not resolved for loaded XREF (open the host file to check if it is loaded) and you can’t find the file in any folder, you simply do not have it. I usually click on Export Report at this time, and examine host files to see if a missing XREF can be safely detached or whether I need to hunt them down.
  • If you have any image references, their re-pathing is identical to re-pathing for XREFs.
  • You do not need to worry about Plot Configurations because your plotters/printers are different anyway.
  • Missing Plot Styles will result in problems with plot line thickness and colors, but in a pinch you can try Monochrome.ctb or Monochrome.stb
  • If there are “not found” Fonts and Shapes, try to purge everything, and then run the reference manager report again. If the font is still not found and you can’t get it, AutoCAD will use the substitute font. Alternatively, you may want to use a font mapping table to specify which font AutoCAD substitutes when it encounters a text object created with another font. Windows True Type Fonts are independent of AutoCAD resource folders; they belong to the operating system.
