Unable to export multiple bodies for optimized cutting
I've made a turtlelarium in FreeCAD:
How can I export it optimized for cutting? e.g.
FreeCAD file:
Any relevant info is appreciated! ^-^
FWIW i've tried to export it as flatenedSVG to use Deepnest/SVGNest but i am unable to export invidual pieces as the `Flattened SVG` and DXF files just generate a top-side view:
Tried to export the shapes using lcinterlocking workbench and then nest them in freecad which generates the flattened parts, but complains about "faces":
Exporting the flattened SVG in SVGNest causes infinite loading:
---
Expected end-result:
- [DONE] Flattened svg/dxf file
- [HELP_WANTED] Nested image optimized for cutting

Re: Unable to export multiple bodies for optimized cutting
Welcome to the forum!
1. Please read the red banner at the top starting with IMPORTANT...
2. Post all images and files here. Your FreeCAD file will expire in 6 days and the topic will become useless for future users.
3. Ask a proper forum question: what you want to do, what you tried, what was the result, what was the expected result.
Your current post is a borderline case. I thought it's a spam and you almost got banned, but then I found link to the FreeCAD model below the image on an external server.
We're really friendly crowd here - please make some effort to help us help you..

Context: Made it to reference my issue, bcs none was answering me on Matrix and IRC on the subject and i didn't expect to get answer here fast enough. So integrated it that way to be able to ask in multiple places u.u
Re: Unable to export multiple bodies for optimized cutting
OK, much better now! Thanks!
I'm new to this - check my results. - what's the final result you need? A dxf or svg with all parts close as possible ready for cut? I don't see any errors, but SVGnest have problem with digesting the svg, but (TypeError: p.pathSegList.appendItem is not a function) but that's way outside of FreeCAD, so I'm not sure how to help.
dxf made in FreeCAD
svg produced with inkscape.
Edit: SVGNest can't even convert simple 4 rectangles file in inkscape SVG and plain SVG format.... I guess I just don't understand how to use it.

Re: Unable to export multiple bodies for optimized cutting
Yep! Where the main motivation is to make it more economical and reduce waste ideally -> I would like to optimize the sizes that way e.g. if i have 1400x800x400 it should produce around 100mm2 of waste which can be reduced by using 1400x800x500 to get 0mm2 waste
Your export has the same issue as mine which generates a huge amount of waste (red color):
Which according to GIMP the pixel difference is 340461 black to 220005 red -> 340461 / 220005 = 1.5475148 ~= 150.5% -> I have to pay ~50.5% more for the order.
So i need to optimize this for cutting where the ideal (and possible with measurement optimization) scenario is 0% waste
Re: Unable to export multiple bodies for optimized cutting
OK, I'd suggest to get in touch with the author of the Laser Cut Interlocking and ask him for help or maybe suggest implementing the nestsvg algorithm.
P.S. I just found out that the workbench is experimental and the author doesn't seem to be active. So you're flying solo: manual placing or the parts, find out what's wrong with nestsvg or find another tool....

Re: Unable to export multiple bodies for optimized cutting
FreeCAD has nesting engine (https://forum.freecadweb.org/viewtopic.php?t=23484) i just can't import the shapes in it, bcs it complains about "faces"
Re: Unable to export multiple bodies for optimized cutting
So i assume that this is a user-error of me mishandling the objects :/
Re: Unable to export multiple bodies for optimized cutting
OK, I didn't know about the built in nesting. Yorik might help.
Re: Unable to export multiple bodies for optimized cutting
How do i ask yorik to help? I already posted https://forum.freecadweb.org/viewtopic. ... 10#p517823, but none seems to be responding to it
