Question about Script

So, if I test both of the document sizes you listed above with the default settings of the script, everything works just fine. I think your issue is with the dialog inputs and the script calculation. For example, if I only change `min` to 5, the script will create a path item...

But as you can see from the path properties in Ai, something wonky is happening...

If you inspect the path item properties in ExtendScript you can see it has 0 path points and this is why nothing is showing in my example.

[PathItem ]
area: 0
controlBounds: 8334,-8334,-24432,24432
geometricBounds: 8334,-8334,-24432,24432
height: -32766
hidden: false
left: 8334
length: 0
pathPoints:
  length = 0
position: 8334,-8334
selected: true
top: -8334
visibleBounds: 8334,-8334,-24432,24432
width: -32766

 Since I don't know your actual inputs, this is all speculation on my part. If you want to share your dialog inputs I can look into it further. Cheers!
