Hello!
I’m trying to create a shape based on two rails but sweep2 connects the wrong end of the curves no matter how I orient the curves or or rebuild them. If you open the attached 3dm file it will be obvious what the shape should look like. Any help appreciated.
Welcome to the forum. I’m not clear what you are trying to do: could you confirm which curves are the rails and indicate which of the other curves are included in the shapes?
