I am new with rhino and grasshopper. we are trying to do a bridge on grasshopper, we have the central line, and surface itself. What we need to do is put ribs in every 2 meters (could be variable) below the deck. But the problem is that the deck we have is sloping, its not flat. When i try this script on a flat curve, it is working as we want, but as soon as i define a curve that is sloping, then the rips starts to twist around. ( I use curve array to array my arc ((ribs)), i think that is what causes the problem.
You can see the screenshots, we will be really glad with your help. Thanks in advance.
