Successes with deepnest - using DXF input?

[blw (Brian Wong)]

Has anyone had consistent success with DXF files in deepnest.io, either standalone or the version that I am told is integrated into Llightburn?

Using the standalone version I consistently get whacko imported dimensions, even on some simple DXFs. As one really simple example, I drew a rectangle 7" x 10" and it imported as 2.6" x 4" or something similar.

I tried a similar test with SVG and that seemed to work fine. But my workflow comes from FreeCAD or QCAD, both of which produce DXF and not SVG.

My impression is that LB has integrated a copy of deepnest, which might mean that it has bugfixes.

I can’t try it myself as my eval license has expired and I’m waiting until my xtool S1 gets proper LB support before extending it.

It looks likely that Deepnest is interpreting the entity dimensions in your DXF as centimetres. Units in DXf’s can be a bit hit and miss and is a common issue.

EDIT:
Have a look at your DXF import settings in Deepnest.

Hope this helps.

Ah, thank you! It was millimeters, not centimeters, but the right idea. Somehow I had overlooked the fact that there were both display unit and DXF import unit settings.
