Block diagram messed up

[truskawka]

Hello, my block diagram messed up by itself. All the wires are spread all around the block diagram, there are wires everywhere and i cant even delete. Additionally, some of the elements on block diagram are not seen and loops are on other loops but Surprisingly it is working.

I tried to recover from Windows Restore previous versions, Labview temp file but it didn't work.

Are there any other idea?

This is common when your block diagram gets outside of a specified range (the exact values are escaping me at the moment).  Simply put: your diagram got too large.  Try shrinking your diagram some and hopefully it will come back.  If not, I really hope you have a backup, either in Source Code Control (preferred) or a copy, that you can revert to.  Use subVIs to modularize your code is probably the easiest way to avoid this ever happening.  Generally, it is best to keep a diagram limited to a single monitor screen.

By no means clear what to do. Are they wild wires those horizontal lines in the navigation window? If yes, try to go there and Clean them up.

Crossrulz may not have a very accurate 8-Ball.

I would look for Structures that have the auto-grow property disabled and sections that are excluded from Block diagram Cleanup. 

As a fast rebuild take the following steps. 

• Close your offending vi
• Close and reopen LabVIEW
• Go to Tools>Options> and enable automatic grow on Structures 

SUPERPRO TIP: to completely reset options close LabVIEW then rename LabVIEW. Ini

• Open the offending block diagram
• Select all <ctrl+A>
• Create snippet from the selection 
• Close the offending vi
• Create a new blank vi
• Drop the snippet on the empty block Diagram 
• Hit Block Diagram Cleanup <Ctrl+U >

That should have solved 100% of the Structure settings and hidden code.  You will need to do some work afterwards to segregate some sections of your code into appropriate subvis and learn better coding practices.

Start reading here.

(I agree that this is most likely the core of the problem)

:Autogrow disabled" does not cause wires going nowhere, whiteout sections, etc.

I am sure that the diagram in the specified range, i have much larger diagram without any problems. unfortunately there were not any backup

it can not be deleted, probably it is belongs to some loops when i dleete some loops it is getting deleted.

It's not the absolute size, but the coordinates of the items. You can have a small diagram that is positioned near the edge, exceeding the valid range and experience these issues.

Autogrow is already working but i disabled and re-enabled for Fast rebuild option but didn't work.

SUPERPRO TIP also didn't work. When i tried to create snipped i am having the save screen but when i click on save button the snipped file is not creating in the specified folder.

Actually I suggested to Clean up (right-clicking on the wire), not to delete.

But probably this will not work.
