LunchBox 2D Truss Not Accurate?

unhandled

#1

I’m not sure if losing my mind or missing something fundamental about GH but when I make a 2D truss from LunchBox between 2 straight lines with the same length the intermediate horizontal members are not straight. If someone could please set me straight I would be most thankful. See below for images and script.LB_Truss_2.gh (19.2 KB)
