Weird packing process
Hi there, Could you please have a look at two packs below. The first one is working with keepFlat flag enabled and another one without. Both variants use the same list of boxes (please see jsons).
Many thanks for your help!

Hi @pikil
Before I take a look in detail, could I please just check if you've plotted using the correct axes? I've had a few reports about weird packings that have been down to confusion about which dimension/direction the co-ordinate system used by BoxPacker is, as sometimes people use a different one.
https://www.boxpacker.io/en/master/getting-started.html and https://www.boxpacker.io/en/master/advanced-usage.html have the relevant diagrams.
Thanks, Doug
Hi Doug, Sure, no problem ;) Unfortunately, I had to move on, so I do not have the calculation for the exact example above available, but I'll just use the similar numbers from scratch, as that is easier with regards to screenshots.
- The big Plate like panel at the bottom of the screenshots (below the beginning of coordinates) is a standard pallet and is not included in the calculations, it just dictates the measurements of the 'box'. It's height is standard and equals 100mm (included in the frame measurements).
Many thanks Doug!

P.S. Happy to provide ItemBox class if needed.
Hi Doug, The updated version 3.6.0 seems to pack boxes much better now, thanks a lot for the changes! Let me know if you need to see the new images for the same list - happy to provide that.
Thanks, Ilia.
Awesome, good to hear. I think there are potentially more improvements that could be made here so I'll keep this open for now
