:bug: The imported DXF file is broken down into several parts

[nicorre]

Hello !
First of all, thank you for reviving this project, which had been abandoned. It's a really useful tool !

However, I've noticed something rather strange: when I import certain DXF files into DeepNest, they appear in several pieces even though they correspond to a single part with continuous lines (and I've grouped the elements in QCAD). For example, see the attached file (change extension txt -> dxf). I get the base panel + a few small squares...

face.txt

• OS: Windows10
• Version of deepnest : 1.5.6
• CAO used : DXF generated from Autocad Fusion

It is not a bug in the true sense of deepnest. Since there are several objects here that present a closed path, these are also taken as closed paths. Each closed path is currently a valid single object for Deepnest. Unless there are "holes", i.e. closed paths within a closed path.

Hi Dexus
I understand the logic better now. But I don't understand the point. Why not import the DXF files as they are? Many files become unusable because of this...
The file appears correctly in the preview window on the right. And when you select on the left the paths to be nested, they are displayed correctly in the DXF. Is there no way to merge these tool paths?
