Hey there,
I have got a few questions on how to tackle these problems through zscript…
#1 How do i test if a Model has UV’s or not ?
#2 How do i click ok within Script, when the “This is an undoable operation” pops up ?
#3 How do i make an clickable Note ? Like an advanced Interface or sth ?
Would be awesome if there is someone who knows this 
Thank you so much

#1 You can use something like this:
[If,([IExists,Tool:UV Map: Delete UV]&&[IsEnabled,Tool:UV Map: Delete UV]),
[Note,“This model has UVs”]
]
The IExists checks that there is actually a Delete UV button, as some 3D models don’t have it (for example, zspheres). If it’s there and enabled it means there are UVs (as they can be deleted).
#2 Sometimes you can wrap [IKeyPress,13, /command here/] around the button press but this only works if pressing enter on the keyboard gets rid of the dialog and continues with the action. For example, using it with Tool>Subtool>Delete won’t work because pressing enter cancels the action.
#3 As Doug says, it’s all in the docs!
Awesome, thank you !
Wow, so there is really no way to click ok or disable the popup ? That’s kind of annoying 
Anyways, thanks
