Unroll and arrange brep issue

Hey guys, I unrolled my breps for fabrication. I would like to print the numbers at the bottom side of the unrolled brep, so that it is inside when they are folded. Everything works and looks well, but when I begun to fold the elements I noticed that the segments are unrolled in different directions (some with the front side on top, some with the front side at the bottom - for exmaple element D39 and D13) so that some elements are printed with the numbers on the wrong side. Is there a way to say gasshopper that all the segments shall be unrolled in the same way (all front sides at the top or all front sides at the bottom)?
Any help apreciated!
