Hi everyone, I´m using Rhino 7 and trying to nest the closed polylines to optimize the laser cutting however, the result is not the proper one. Some polylines are not included in the sheets, and the result is not optimized regarding space wasting. I played around with the parameters but I couldn’t find the solution. Could anyone give a hand on this? I really appreciate any help you can provide, thanks in advance.

Setting ‘Rotations’ to 5 does the trick. Some of the parts are too big to fit on the sheets unless they are rotated more finely.
Increasing the ‘Y’ dimension of the sheets also works. This is ‘Y’ = 5.6 with ‘Rotations’ = 4.
Most of the the polylines are not in the XY plane, but that’s not the problem,
Hi @Joseph_Oster thanks a lot for your quick response. I´ve set the “Rotations” to 5 as you suggested and it works much better, now I would like to understand why 5 is the correct election, in other words, how the “trick” is done 
.
3 rotations = 0, 120 and 240 degrees
4 rotations = 0, 90, 180 and 270 degrees (the last two effectively duplicate the first two)
5 rotations = 0, 72, 144, 216 and 288 degrees (best chance of success)
