DXF contour import errors

[CNCppCad]

Application: KiCad (64-bit)
Version: (6.0.4), release build
Libraries:
wxWidgets 3.1.5
libcurl/7.78.0-DEV Schannel zlib/1.2.11
Platform: Windows 10 (build 19045), 64-bit edition, 64 bit, Little endian, wxMSW

Hello
I imported the outline from Freecad into a DXF file.
With LibreCAD I deleted the unnecessary lines and holes and saved the DXF file again.

After importing into KiCad 6 and checking the design rules, I got the following error messages :
Error: The PCB has a poorly formed contour (self-intersecting) Line on Edge.Cuts
(See Kicad 6 - Board.png)

Only curve sections are affected

I also imported the DXF into EstlCam CAM software. No problem, the PCB can be cut perfectly.

Is there :

• a hidden defect in the DXF
• a problem with KiCad 6

Can KiCad 8 add new features?

@CNCppCad

Only curve sections are affected

I’m not sure this is correct,you have arrows at all the corners suggesting there is an issue there also.

I have seen DXF imports import a duplicate set of lines before . . . perhaps you have that ? An easy way to tell is click on one of the straight lines to select it , then Del key to delete it . . . if you still have a line in that position then you have duplicate lines.

Yes it’s true
In Freecad I had exported the 2D face to the PartDesign workshop. Error, it had to go through the Draft workshop.
When I re-imported the DXF into FreeCad, I noticed that the lines and arcs were duplicated several times.

Thanks

For Single-Line DXF’s, there are Correct settings for Import/Export for Kicad and FreeCAD.

I’ve posted them several times so will post only From FreeCAD to Kicad. You can explore settings for Kicad to FreeCAD…
