yeah that looks about right. It's black because the rectangle has a black fill. Just set it to no fill and black stroke. Honestly for near-rectangu…

could you send me the polylined svg? It actually packs it to the left, so I'd suggest rotating the bin so it's horizontal. Working on making this a…

could try the "export makercam svg" option? http://forum.librecad.org/CAM-capabilities-in-LibreCAD-td5711890.html Funnily enough, I also made maker…

yeah I see the problem. The shapes are formed with separate lines instead of each shape being a separate path. is there a way in librecad to merge …

could you open the svg in a text editor and just paste the code here?

unfortunately I rely on some new APIs for multi-thread, so a fairly recent browser is required. Does the demo work ok?

hey tytower what browser/os are you using?

Not allowing parts to be rotated at all

the paper's behind a paywall, but I'll have a look at the library when I get a chance. using the center of gravity instead of an extreme point is a…

So to answer the original question (in case you weren't kidding). The solution space is too vast to find the exact optimal solution, so the GA cont…

@Jack000

yeah the api is currently only abstracted to the level of SVG inputs rather than polygon inputs. It would take a bit of refactoring to also take ou…

"Performs similarly to commercial software"... which one?

Can run demo at local?

@Jack000

so the biggest size thing is the starting point. The more iterations that are run, the farther you get away from that order via mutation. material …

@Jack000

setting rotations to 1 should ensure all parts maintain their orientation. I think you may have clicked the x icon instead of "save". That cancels …

@Jack000

Right, I mean that instead of 2 closed paths we'd end up with 3 open paths in the output. Currently the output is simply the input svg paths with s…

@Jack000

yeah it opens a new sheet under the first one

Jack000 commented on issue Jack000/SVGnest#7
@Jack000

someone else mentioned this to me too. I think it's do-able but not necessarily a trivial change, the 2 co-linear parts would have to be split into 3.

The NFP algo would be faster in C, but I'm not sure how much. It's essentially a massive amount of floating point operations, which I assume would …

yes this is a limitation of webworkers. It needs to be hosted somewhere to run multiple threads. SVGnest uses parallel processing to speed up the a…

ah, have't tested in edge yet. I'll have to look into that

I think mynesting is the only one with a pay-per-use model. There's also nestfab which uses the same engine. In the demo case most nesting programs…

Jack000 commented on issue Jack000/SVGnest#4
@Jack000

does the demo have the same error? What browser/version are you using?

Jack000 commented on issue Jack000/SVGnest#3
@Jack000

I just didn't want to call them out specifically. But it's the one with the pay-per-use model : ]

Jack000 commented on issue Jack000/SVGnest#2
@Jack000

I think it does eventually get it, but because the optimum solution is rather far from the initial decreasing size heuristic the GA needs to run fo…
