I am trying to design louvered shutters for my house. I have seen and read about arrays, but it seems that the user just always type /4 or whatever to place four objects in an array. But in my case I have a distance, say 31 inches and I have louvers that are 3/8" apart or about that depending on the spacing. How do I tell Sketchup to place louvers from point A to point B evenly? The louver will be a component as will the stiles ( which are taking the ends of the louvers). I hope I am being clear enough to get an answer. If not please let me know and I will tryo to clarify.
