Some DXF polylines are not displayed

[mage0r]

I've got some files that are missing components or don't show up at all and I don't know why that would be.

I can't see any log files or the like to indicate if something has gone wrong.

I've attached one to help diagnostics.

Thanks.

deepnest uses svg internally, so if you are able to use svg I'd usually recommend doing that. The dxf import happens via conversion, and unfortunately some newer versions of dxf may not work. If you can, try exporting the dxf with version number prior to 2012, like this:
