SVGnest Great if it could keep groups together

I make a lot of jewelry and this would be hugely useful if it kept groups of objects together.

hey mirzu

do you mean svg tags or physical clusters of objects? I don't have any background in jewelry, so it's not obvious to me how this might work.

SVG tags. Right now the parser takes them apart and places the polygons individually. If it kept the groups together and only placed the outermost group it would work perfectly for me.

Feb 22 '16 14:02 mirzu

hmm.. so you would like certain parts to keep their relative positions, as if they were a single object? I'm just not quite sure how this would be useful in the context of jewelry making.

Feb 22 '16 14:02 Jack000

Here is an example file that I tried to name the different parts so this would make sense. https://www.dropbox.com/s/r52u5j6w7t1tv4t/slinky-vector.svg?dl=0

The groups with id "keep_together" and keep_together_copy" are what I would love SVG Nest to keep together. They contain shapes that will be cut and etched to make each piece of jewelery.

How it looks when cut: evernote_basic

How it looks in the drawing program, black is etched, red is cut. slinky-vector-minimal_idraw

ah I see. In this particular case it should work as-is.

The paths that are used for nesting are the paths that are not contained by other paths. If a path is contained inside another path, it will be grouped with the outer path. So in the given example all the paths would be grouped with the outer red path.

if you have a collection of paths without a path to enclose them, you could create the enclosing path by hand or use offset+boolean operations.

it is possible to make a feature to do this as well, but like the other suggestions so far it's do-able but not exactly trivial to implement.

It would also be helpful if a compound path could be kept together. (That's an Illustrator term for a path node with a single d attribute defining the full shape including separate pieces.)

I would have liked for groups to be kept together as well, even if only uncontained paths are considered: that's not how I expected it to work, and I can imagine it being useful in a few cases.

Take the following svg for instance, svgnest is stuck on "placement in progress"

expand svg code, as I cannot attach it as a file
