Create a custom message parameter

MPach — Wed, 24 Jun 2026 15:05:38 GMT

I'm using ArcGIS Pro version 3.3 and it doesn't appear to have the option to enter a Custom Message like is available starting in version 3.5 for Modelbuilder. I can hack something up by putting in a String variable then making that a parameter and setting the default value to all asterisks like this

But ideally I'd like a better way to display a message on my geoprocessing dialog box for this tool. Is there a better way than this? I can't seem to find a better solution on the internet.

Thanks,

Mark

why not just put the variable name (Select the rows... etc) in place of the *'s

and change "Select the rows..." to something like "Note : ...."

I doubt that there will be a backport of the 3.5 capabilities

That's not a bad idea either. I was just trying to grab the user's attention with the asterisks. I'll give your idea a shot and see which looks better. Thank you Dan.
