Grid surface

tanya forum
if i have a grid like this how can i get the value of the existing grid at the edge as i marked can it use python? thank you

If by values you mean the points, and if python isn’t mandatory, this could be a way to get the points !
Is it what you needed?
The value list switches between two options, didn’t know how you wanted the output data to be !

Outpoints.gh

yes that’s what i need thank you sir
