Plywood box - How to layout for cutting?

So I have a box of plywood but want the sheets laid down flat for a cutting layout.

I tried searching the forum but couldn’t find out whether any such command exist. If no such command exist, what would be the quickest workflow to get to a layout for cutting?

Do a search for Nesting and you might look here:

Hi @Fred_C,

RhinoNest wasn’t for free… but I found OpenNest on Food4Rhino:

In my case the sheet layout is quite easy to optimize manually though, so I was thinking more about how to quickly extract single surfaces from the 3D-plywood box and having them quickly oriented on a CPlane so I can then manually put the layout on the full size plywood sheet.

Nope, didn’t say ‘free’, but you are on the right track.

Use Make2D

Make2D gives me three views, but not all individual (different) pieces for the layout on the full sheet. Or did I miss something? (I need all individual pieces to be placed in the layout)

for nesting there is also the open source https://deepnest.io/

(does run outside Rhino though)

It give you the pieces flat on the CPlane of the top and two sides. You could mirror the front and side to get the back and the opposite side and then just arrange them manually on sheets. Not sexy but will get you there.

Top and bottom are different. Front and back are different too… and sometimes the sides are also different. :slight_smile:

you can always make2d each face separately if you’re a glutton for punishment!

UnrollSrf will “unroll” the surfaces of a box or other shapes with flat or “developable” surfaces onto the xy Cplane. If Explode=Yes each individual surface will be separate when unrolled. If Explode=No the surfaces will remain joined but split as needed for unrolling. The splits may be arbitrary. After unrolling the surfaces will need to be rotated and moved into position for cutting.

Hm. UnrollSrf seems to unroll only one polysurface at the time, so it seems faster to just explode everything, then delete the excess surfaces, then rotate the Srfs I need, and then project them all to the XY Plane. These manual steps thus seems to not have a dedicated command. I guess I will have to script it then.

But thank you all for your suggestions. At least I now know I’m not missing anything. :cowboy_hat_face:

there are 2 multi unroll scritps packed into this topic, maybe it helps.
