Hi Forum,
i want to subtract every value in this with the next value to get their difference out. I have managed to get every single value from the list with the “List.GetItematIndex” node. My question is now, how can i do that without any user Intervention to get the DIfference of the values in the list. Or is there another, simpler way to do that?
Thank you in Advance!
Wow Thank you very much Nick, thats so much easier and more elegant! 
Hey Nick
I still have a question in which I can not get any further, maybe you can also help me there. i want to combine the two lists, the lists are already in the right order. I want to set a parameter with the names in the first list and take the values from the second list. Can you perhaps suggest a solution?
I think you’re looking for the first output but I included the second one in case you wanted your items paired.
What are you going to do with your parameters and values? I only ask because if you’re wanting to give those parameters those values you’ll likely want to keep them separate.
Something like this, now I want to filter the values for each parameter from the list by typing the name. So here in this case, that would be, I enter “Terrace” and the list gives me the value for this would be 17.99. I do not know if I could explain it well what I mean.
I’m not sure what to do about your blank parameters but I think you’re looking for a dictionary. You specify which values go with which keys (parameters in your case). Then whenever you give the dictionary a key, it returns the specified value.
Great:+1: Thank you again!
Hey Nick, I need your help again, I have the following problem, I need the distance of the outer wall to the property line, but first I have to check if the property line and the outer wall are parallel. if that’s the case i need the orthogonal distance. if that is not the case i need the shortest distance. how can I proceed best? i guess i need the wall and the property line as vectors, but how do i continue after that?
