Set value by length and slope pipe

hello, I am trying to find a way to set value based on pipe length and if it sloped or not, any ideas?

but i didn’t work the error message was: “Warning: Element.GetParameterValueByName expects argument type(s) (Element, string), but was called with (string, string)”

Pipe length node input is wrong you should feed it with elements not with string of slope value.

thanks for replying, the problem that i have to filter the slope value, i need to get the pipes that doesn’t sloped , thank i need to get the length of it !

thanks a lot :slight_smile:
