I am facing problem with block diagram.when I open(Control+E) the block diagram,unable to see it.
When I press the button from Front panel, it links to corresponding block in Block Diagram with some dotted lines(Block Diagram not visible).
I am still able to save and build the entire project and it seems working fine.I can search the text contents,which gives the search result.
Suggest me If I had pressed some shortcut and messed entire block diagram.
U can check that in attached image.Please help me with that.
Solved! Go to Solution.
Attach the VI. If you attach a picture of a blank VI, what do you think we can do with it? Attach the actual VI, a file with the extension ".vi". If you have an "older" version of the same file, attach all of them (you may have to rename the older ones).
Looking at your picture it looks like you are not centered on your block diagram. You have selected a hidden control or indicator and it is way off of the screen. Try moving your scroll bars to find you code.
It's also possible your block diagram elements have locations that are way too large such as beyond the limits of an I16 number (-32768 to 32767) and that causes corruptions when LabVIEW tries to display them.
Aha -- I wasn't thinking about the "Too Big Block Diagram". Do attach the VI, but you can also "see for yourself" by doing the following:
I have attached the "vi" file for reference.please check and help me with that.
That's weird, its like everything on the BD except the Tab-control is hidden. The hidden things can be selected and moved, but there is no structure hiding the code.
I think this would be a good time to revert from the latest version of your VI from your SCC.
"The VI" is 10 MB! That is enormous. Are you storing lots of data as default? Although it will not help the problem, its bad practice.
quite interesting VI profile metrics:
The diagram is less than 60×60 pixels, but has more than 23000 wire sources…
(Also) my recommendation: get an older version of this VI from your SCC system. Or from your backup storage, when you don't use any SCC (which you really should!)…
