Hi Husky

Just tested with quite a few parts and it worked great, apart from this file, somehow it seems to of reversed some arcs? any idea what might be going on... it's in metric, was going to nest on a 2400x1200mm sheet...see picture and attached file..

Pls, attach your files.
That would not be the first issue with SVG.

Rather all arcs look to be reversed in your screengrab.

The dxf and the re-imported svg consist both out of 53 non-reversed arcs.
Setting something else as 'White' and 'Default' for the lines:
Looks ok in a browser.
Opens ok in Inkscape.

So it is a Deepnest issue.
Did you try reversing the arcs, or conbined to a polyline?

Nope - I haven't ask for the dxf :wink:

Hi Both

I reckon it's the nesting program too..
I also opened up svg in inkscape but only displayed rectangle but AutoCAD opened the dxf with no problems..
CVH yes same issue with polylines...
Silly me rectangle was white on white saved from inkscape as DXF and all arcs are ok..👌

Cheers
John

Hi Husky
Deepnest cannot process SVG files correctly every one I've tried so far fails all arcs are reversed..the pc I'm using is offline..I bet it will work while online..pity it looked very promising..

You lost! e_surprised Online / offline does not matter. SVG fails in both scenarios. Good to know ...

Deepnest is what they call 'abandonware'.
Jack Qiao (Jack000) never did surface again after 2018.
https://github.com/Jack000
http://jack.works/

There is a fork with later commits:
https://github.com/InfernoEmbedded/Deepnest

Deepnest is based on SVGnest from the same author.
Last commit there is from april 2019.

Deepnest and SVGnest topics are spread over many sites and pages.
I did came across some demands and commits about arcs but not as we are experiencing.

Found a mail address: jak000 at gmail.com
(had to chop that address or the msg failed as spam)
Many are trying to reach him.

Pitty, it looked promising.
