yes, I understand that I need to refer to the variable by the output name - but does the expression go inside the int feature? it's still not liking that. I am quite literally jut typing in V/50 into the expression field. I also tried Int/50 and still didn't work/ I feel like Im missing something so elementary...
and yes visose, I think that i need to make sure that the 50 value changes proportionate to the sizes of the volume coming from the original surface. thanks
