Model View - "All Tables" diagram totally messed

[gjfbarbosa2]

Has anyone ever seen PBI move some of the tables in the "All Tables" diagram to a place many screens (really many, I didn't count) below the main group of tables?

I know that I can build another diagram and  correct theproblem. I've done it and they work perfectly.

However, the main digaram went totally crazy, and moving the tables back to their place manually does not work.
Any one knows if there is a way to reset this diagram?  

Thank you for any advice!

Thank you so much! I think I'll go straight to the nuclear option. 😁

Hi @gjfbarbosa2 

1. Create a new diagram:

   • In Model View, click the New Diagram icon (looks like a blank page)

   • Name it "All Tables Reset" or similar

2. Add all tables to the new diagram:

   • Right-click in the blank diagram area

   • Select Add All Tables

   • Alternatively, drag tables manually from the fields pane

3. Apply Auto Layout:

   • Select all tables (Ctrl+A)

   • Right-click any table → Arrange Tables → Auto Layout

   • Wait for Power BI to reorganize everything

4. Set as default view (optional):

   • Right-click the new diagram → Set as Default Layout

   • This makes it the view that opens by default

Alternative Nuclear Option

If the above doesn't work, try this more thorough reset:

1. Close Power BI Desktop

2. Navigate to your file location and make a backup copy

3. Rename the .pbix file to .zip

4. Open the zip and navigate to \Layouts\

5. Delete Model.layout (this contains the corrupted layout)

6. Rename back to .pbix and reopen

Prevention Tips

To avoid this issue recurring:

• Use multiple diagrams for logical subject areas

• Save frequently during manual arrangement

• Avoid excessive zooming/panning while editing

• Consider using external tools like Tabular Editor for large models

Important Notes

• The "All Tables" diagram is special - it can't be deleted but can be reset

• Power BI sometimes loses layouts with:

  • Very large models (50+ tables)

  • Complex relationship patterns

  • Multiple monitor setups
