Each document has a status: + +* **Added** (green circle) – The document exists in your current state but did not exist in the selected revision +* **Modified** (yellow circle) – The document exists in both versions but has changes +* **Deleted** (red circle with minus) – The document existed in the selected revision but no longer exists in your current state + +### Element-Level Differences + +At Level 2, you see which elements within a document have changed. For example, in a page, you might see which widgets were added, modified, or deleted. In a domain model, you might see which entities or associations changed. + +### Property-Level Differences + +At Level 3, you see the specific property values that differ for a selected element. The grid shows three columns: + +* **Property** – The name of the property (shown as a tree structure for nested properties) +* **Older** – The value in the historical revision +* **Newer** – The value in your current state + +Grey rows in the property tree represent intermediate path levels without a direct value.

The pane returns to a blank state and is ready for you to start a new comparison. Documents that were opened as part of the comparison remain open in your editor. + +## Common Scenarios + +### What Changed Since This Commit? + +To see all changes made since a specific commit: + +1. Open the History pane and find the commit in question. +2. Right-click the commit and select **Compare to current state**. +3. Review the document, element, and property-level differences. + +This helps you understand the scope of work done since that commit, whether by you or other team members. + +### What Would Reverting to This Revision Undo? + +Before reverting to an older revision, you can preview what would change: + +1. Open the History pane and find the revision you are considering reverting to. +2. Right-click the revision and select **Compare to current state**. +3. Review the differences to understand what would be undone by the revert. + +This helps you make an informed decision about whether reverting is safe or if it would undo important work. + +### Did My Recent Changes Affect This Area? + +To check if your recent uncommitted changes affected a specific area of your app: + +1. Open the History pane and select your most recent commit (HEAD). +2. Right-click and select **Compare to current state**. +3. Look for the documents or elements you are concerned about. + +Because the comparison includes uncommitted changes, you can see the full impact of your current working session. + +## Tips and Tricks + +* **Use Expand all and Collapse all** in Level 3 to quickly show or hide all nested property paths. This is especially useful when comparing complex elements with many properties. +* **Right-click any cell** in the grids and select **Copy** to copy the cell value to your clipboard. This is useful for documenting changes or sharing information with your team. +* **Press Enter to drill down** and Backspace to go back when navigating the comparison. This is faster than using the mouse to click buttons. +* **Understand version conversions** – When comparing older revisions, remember that model conversions may introduce minor differences in how properties are displayed. These do not affect your stored revisions. + +## Read More + +* [Comparison Pane](/refguide/comparison-pane/) +* [History](/refguide/history-dialog/) +* [Changes Pane](/refguide/changes-pane/) +* [Version Control](/refguide/version-control/) +* [Using Version Control History](/refguide/peer-review/) diff --git a/static/attachments/refguide/modeling/menus/view-menu/comparison-pane/comparison-pane-level1.png b/static/attachments/refguide/modeling/menus/view-menu/comparison-pane/comparison-pane-level1.png new file mode 100644 index 00000000000..0bcd8b3bd83 Binary files /dev/null and b/static/attachments/refguide/modeling/menus/view-menu/comparison-pane/comparison-pane-level1.png differ diff --git a/static/attachments/refguide/modeling/menus/view-menu/comparison-pane/comparison-pane-level2-3.png b/static/attachments/refguide/modeling/menus/view-menu/comparison-pane/comparison-pane-level2-3.png new file mode 100644 index 00000000000..686d5c1146e Binary files /dev/null and b/static/attachments/refguide/modeling/menus/view-menu/comparison-pane/comparison-pane-level2-3.png differ
