Overlay: Use this button to overlay both versions on top of each other. Both files display at their original colors. Use the slider to change the transparency of each file - left to dim the compare version, right to dim the open version.

Overlay Differences: With this button, the compare file version opens overlaid on the open file. The open file displays in color1(deleted geometry), and the compare file displays in color2(added geometry). Geometry that has not changed (common between both revisions) is color3.

Side-By-Side: Both versions are displayed in a split-screen image. Move the slider to view transparent differences overlaid in each version.

Text Comparison: While a graphical comparison is useful for viewing differences in CAD drawings (as overlaid images), this method has limitations when it comes to comparing the actual text contained in a document file. Use the Text Comparison mode to view the (non WYSIWIG) text content comparison of the open and compare documents.

The document is shown in split screen mode with the open and compare files displayed in two windows as lines of text, and the WYSIWIG view of the Compare or Open file shown beneath. Text differences between the two documents are highlighted in three different (custom) colors.

Color1 indicates something that was deleted out of the open document.

Color2 indicates something that was added to the compare document.

Color3 indicates something that has changed between the two documents.

A merged report can be exported to PDF using the Text Compare Report button.   

Open File (Only): Only the file that was first opened is displayed (normal colors).

The set alignment points for comparison tool is available in this mode. All Annotate, Review,  Measure, and Publish features are supported in this compare mode only.

Compare File (Only): Only the file that was opened for compare is displayed (normal colors). The set alignment points for comparison tool is available in this mode. Measure and Publish features are supported in this compare mode.

Additions: Only added areas (areas present in the compare version, but not in the open version) are displayed in custom color1.

Deletions: Only deleted areas (areas present in the open version, but not in the compare version) are displayed in custom color2.

Unchanged: Only areas that are present in both the compare version and open version are displayed in custom color3.

You can close the comparison file (and toolbar) at any time by selecting Close Compare from the File menu.

Nudge Alignment: This button is available when using the Overlay, Overlay Differences, Side by Side, Additions, Deletions, and Unchanged viewing modes. You can use the Nudge Alignment commands to nudge and re-scale a compare image or drawing to an open drawing, allowing you to interactively make small adjustments to align the files more precisely. This feature is especially useful for comparing two TIFF images that contain the same text but have different line spacing. Click the Nudge Alignment button and select a direction to nudge the compare file by one increment.

Set/Clear Alignment Points. The Set Alignment Points tool allows you to compare two versions of a file that are of different scales, or world page sizes. Use the tool to select two points on each version that define a single identical location that is used as a common alignment section when the two files are overlaid. Clear alignment clears any currently set points.

Transparency Slider: This tool is available for Overlay, Overlay Differences, and Side-by-side modes to adjust the transparency amount of the two documents. In the two overlay modes, move the slider to the left to reduce the transparency of the Compare document (additions), move the slider to the right to reduce the transparency of the Open document (deletions).

When the slider is centered, both documents display at 50% transparency.

In Side-by-side mode, center the slider to view the changes side by side, overlaid at 25% transparency. Move the slider all the way to the left to view 50% transparency, or all the way to the right for 0% transparency (no overlay)

Text Compare Report: Use this button to generate a merged text compare report and output the results to PDF.

Compare Settings: Use this button to change color options, hide unchanged text (can be expanded/collapsed), wrap lines, and enable smooth scrolling.
