[M.Essam]

Hi ,

i have very wide blockdiagram even after i select all the items and click on CLEAN UP DIAGRAM button i want to zoom it out to see all the blocks and i can't use subvis

You can not zoom in labview but you might find the navigation window usfull (cntr+shift+N)

What kind of application is this?

I can only think of very very few cases, where you can't use SubVIs

Actually I can't think of any reason NOT to use subVIs.

The most interesting aspect of this question is thinking about why you couldn't use subvis. I'm struggling to think of a single use-case.

I have seen cases in FPGA where you need a lot of wires for functional blocks (VHDL nodes, custom devices, etc.) that would be nice to put into subvis (like "acquire" -> "store/log" -> "compare" -> "compute Simulink/Veristand" -> "output", something like that) just to tidy up your block diagram but you wouldn't want to bundle/unbundle or build/index arrays for resource reasons?

Generally on FPGA bundles, unbundles are free anyway since there is no memory, just wires.

The case I can think of is the if you are using locals or implicit property nodes (IF you are unaware of the alternatives to these).

Hi

I can use subvis in my application , sorry i meant to say that i don't want to use subvi

Any way thank you

Independent of the IDE you're using there's some style guidelines you should adhere to.

A block diagram that is so  huge that you consider zooming is definitely an indicator that you should SubVI's. SubVI's increase the readability and reusability of your program.

Saying that you don't want to use SubVI's is a bit like saying you want to write a well-readable book, but without any chapters, interpunction etc..

For what reason?

This conversation reminds me of this quick story: The Dense Forest.
