I have a very frustrating problem. The block diagram of my VI has become perhaps a bit too large (though I tried to keep it as small as possible, there is a lot of stuff going on there) and after my last diagram cleanup some objects have disappeared!! I looked in the forum and it appears that there is a solution
Solved! Go to Solution.
Copy+paste to another vi?
After diagram cleanup, select all and paste into another vi and it should be in visible range.
I tried this but it doesnt work... This is something that NI will definitely have to look into as it renders your VI useless..
it seems that I had not been paying attention... The solution described here was valid in my case as well..
