Hi John,

You should use Extended conditional shape manipulation actions | DataMiner Docs for this. This is nicely documented and should look something like this:

Hide : <A>-A|Value|[var:MyVar]|=0

Do note that 'Hide' first loads the shape and then hides it after the condition is fulfilled. When you have a big Visio, then you'll see this effect. You can also inverse the condition and use 'Show' instead. It depends on your use case and preference.

Kind Regards,
Jarno
