Help on authoring x151 (Square Rubber Belt)

[Philippe Hurbain]

So you are able to measure a floppy rubber band to such a high precision? I'm impressed
Use approximation!

Code:

0 BFC CERTIFY CCW
0 BFC INVERTNEXT
1 16 0 0 -2 0 0 16.7 16.7 0 0 0 4 0 4-4cylo.dat
1 16 0 0 -2 0 0 20.875 20.875 0 0 0 4 0 4-4cylo.dat
1 16 0 0 -2 4.175 0 0 0 0 4.175 0 1 0 4-4ring4.dat
1 16 0 0 2 4.175 0 0 0 0 4.175 0 -1 0 4-4ring4.dat

OK, the band is a bit thicker... by 0.07mm ! I defy you to be able to measure this...

Note also that I measured the rubber belts I have here, there are not two with the exact same size. Average seems to me closer to 15mm (middle of belt)/1.2mm, giving this code:

(edit: the version I initially submited was off in size...)
