Comparing documents

To compare files, Meridian Enterprise displays a unique multi-pane window. Two of the panes show two files side-by-side. The two files can be two revisions of the same file or two similar but unrelated files that you want to compare visually. The area of the files shown in the two panes are synchronized with one another. When you change the view of one file, the view of the other file is changed automatically to match the first file. This makes it easy to compare files without adjusting the views, sizes, and positions of separate windows. If the files being compared are supported vector (CAD) graphics files, the lower right pane shows the additions, deletions, and unchanged objects between the two files in configurable colors. The lower left pane contains options to change the colors. This graphical representation of changes is valuable for quickly determining the differences between two complex files. You can print a hard copy of the differences and also generate a report of the non-graphical differences between two files, for example, layer names, system variables, and so on.

Note    Graphics that have been moved but that are otherwise unchanged are considered by Compare as a deletion from one document and an addition to the other document.

Note    This command is not supported for work areas by Web Access.

To visually compare two documents:

  1. Use Ctrl+click to select one of the following:
  1. Click the Compare button . The Compare dialog box appears, similar to the following figure.
  2. Use the tools in the toolbar or the shortcut menu to change the view of the documents. All panes remain synchronized on the same area of the documents.

Note    Automatic pane synchronization is not supported for all formats in all viewer plug-ins, for example, Adobe PDF by the AutoVue 2D Professional viewer plug-in. When working with an unsupported combination, click the Synchronize button to manually synchronize the views.

Tip    Use the browse buttons   or corresponding shortcut menu commands to load different revisions of the same documents, different documents from the vault, or documents that reside outside the vault for comparison. This feature is not supported by Web Access.
