Hello everyone,
One of my co workers is trying to set up a model & drawing that will automatically adjust the spacing of rafters in a hip roof.
The goal is to enter in a length (say 'X') and width (say 'Y') for the roof and get the spacing (say 'Q' because 'Z' is too predictable).
He has noticed that a relationship that stays consistent but can figure out how to mathematically write it out. I feel like it's on the tip of my mind teasing me but I can't get it.
One of the relationships is X=180, Y=70 & Q=112.5 If we add or subtract to X the same happens to Q. Add 2" to X and it adds 2" to Q. If we add or subtract to Y the opposite happens to Q. Add 2" to Y and it subtracts 2" from Q. Does anyone know what formula I would need to write to express these relationships? If so will you please share it with me?
Joe
try Q=X-Y+2.5"
it seems to fit the inputs you have given, though I have never layed out a roof before.
LMAO I knew it was going to be simple, but I just could not break the fog in my head. And to think its only Tuesday. Thanks Jeremy that's perfect.
