The next example is that of a more complex wing planform, similar to that of the F-117 airplane. The data shown is sufficient to define the wing.
In order to make the input file to getmac, the length of the chords at each breakpoint must be known. The LinInterp tool makes it easy to get these points. The leading edges are at 0, 344, 645, and 860 corresponding to y=0,200,375, and 500. From these points, we see that the chords are 1120,400,400, and 0 in length.
