block diagram cleanup fails

[gb119]

Just occasionally I seem to create vi's that the automatic block diagram cleanup just refuses to touch - I hit CTRL-U, the machine beeps at me and nothing else happens. It's not a big deal but I was just curious under what circumstances the block diagram cleanup tool might fail to work ? Today's problem case involves various VI-Scripting calls which I guess might be vulnerable to tripping the cleanup tool up..

Perhaps your block diagram exactly matches what the cleanup tool would do.  That's fantastic!  🙂

Unfortunately I can be pretty confident that my block diagram is not optimally laid out ! Also, in those cases I don't get the error beep. This is defintiely the cleanup routine finding something it doesn't like...

Hi Gavin

we wanna see examples!!!

I'm afraid it's a bit tricky to post an example vi as its part of a larger library. However, I do have a screenshot and you can download the code from http://code.google.com/p/lavacr/source/browse/#svn/trunk/8.6.x/Rusty%20Nails/VI%20Scripting/Scriptin... (this is part of the LAVAG Code Repository subversion archive).

The obviously sub-optimal code is around the inplace structure. Note that the code cleanup broke after I stretched the diagram, inserted the two tunnel property nodesand the inplace structure.

For the curious, the code (which is perfectly functional, just not as pretty as it could be) will programmatically create a case structure, populate the cases and set the case insensitive flag for the selector.

Hi Gavin,

Just wanted to inform this problem has been fixed in LabVIEW 2009. 

Thanks,

It seems to be back (broken) in 2010 SP1.
