Lucidchart layout and revision history not working

Hi ​@Lucid_Endeavour

this usually means the diagram layout was changed, objects were grouped/moved into the same position, or an auto-arrange/layout action compressed the canvas. The good news is you can often recover readability without version history. Lucid’s revision history exists, but access depends on your plan, and it is typically available from the cloud “saved” icon or the menu option for revision history.

Here are some suggestions that you can try:

1. Undo immediately - Press Ctrl+Z / Cmd+Z a few times in case the layout shift just happened.
2. Select the affected area, not the whole document. Drag-select the messy section only. Then go to Arrange and use: 
   • Align objects
   • Distribute objects

           These tools are specifically meant to restore spacing and alignment between shapes.

3. Use Assisted Layout - If the boxes are stacked or crammed together, select the affected flow and apply Assisted layout from the Arrange options. Lucid’s assisted layout is designed to automatically organize objects into a cleaner structure and improve spacing.
4. Check whether objects were grouped - If several boxes are moving as one cluster, they may be grouped. Ungroup them, then re-align and redistribute.
5. Check containers, swimlanes, or frames - If the flow is inside a container, swimlane, or frame, resizing or layout behavior inside that structure can compress everything. Assisted layout specifically works with frames, containers, and swimlanes, so that is a strong clue if the collapse happened “all at once.” 
6. Zoom and page settings - Sometimes the diagram is not actually broken; the page view or document settings changed. Open document settings and confirm the canvas/page setup still looks normal.

Hope this helps.
