Spline (conic curve) import issues from Fusion 360 DXF

[iluha_ua (Ilya Sopov)]

Hi!
I’m very happy since I have started using LightBurn instead of LaserCAD and it helps to save lot of time doing my workflow from drawing idea in Fusion 360 to preparing it to cut in LightBurn. So I would like to thank all team for making this possible.

But today I have faced an issue importing conic curve (spline) from Fusion 360 DXF to LightBurn.
This is how conic curve should look like

and this is how it looks in LightBurn

This is file I’m importing
stickers_stand_dxf.txt (13.6 KB)

Interesting.
Care to share your fusion f3d archive?

Here it goes. Just remove .txt extension in file name
stickers_standv1.f3d.txt (118.5 KB)

Thanks.
I opened your archive, exported sketches as dxf, then re-imported the dxf back to fusion and all overlap exactly. so it seems the dxf corresponds exactly to the fusion design which means lightburn importer alters the file. i was going over all of lightburn settings which seems to have little to no effect. the curves are tiny.

Don’t sure if this could be helpful, but this online tool seems to import dxf correctly:
