Failing at GetBoardPolygonOutlines(outlines, "") with KiCad 6

[TrooperN]

When trying to convert a KiCad 6 kicad_pcb to brd, the conversion fails on line 45, in convert, pcb.GetBoardPolygonOutlines(outlines, "").

Hi @TrooperN and @whitequark ! I don't think this is a bug, not at least in this project. Anyways, I was adapting the code in KiBot and here is the patch I'm comitting:

The GS.ki5() returns true for KiCad 5 and GS.get_modules() is this:

    @staticmethod
    def get_modules():
        if GS.ki6():  # pragma: no cover (Ki6)
            return GS.board.GetFootprints()
        return GS.board.GetModules()

In a quick test it looks like this patch works for the glasgow board.

Hello!

I updated my pcbnew2boardview.py with these changes. Everything seems to be working now!

i'm trying to use the patch of @set-soft but still got error on skip_module function:

Traceback (most recent call last): File "/home/sbonb/git/kicad-boardview/pcbnew2boardview.py", line 158, in <module> main() File "/home/sbonb/git/kicad-boardview/pcbnew2boardview.py", line 154, in main convert(pcbnew.LoadBoard(args.kicad_pcb_file), args.brd_file) File "/home/sbonb/git/kicad-boardview/pcbnew2boardview.py", line 80, in convert if not skip_module(module_list): File "/home/sbonb/git/kicad-boardview/pcbnew2boardview.py", line 11, in skip_module refdes = module.GetReference() AttributeError: 'list' object has no attribute 'GetReference' seems to be a basic error but i can't figure out why...

[TrooperN]

This part:

 # Parts
    module_list = pcb.GetModules()
    modules = []
    while module_list:
        if not skip_module(module_list):
            modules.append(module_list)
        module_list = module_list.Next()

Needs to be changed to:

# Parts
    module_list = pcb.GetFootprints()
    modules = []
    for m in module_list:
        if not skip_module(m):
            modules.append(m)

[neosoyo]

got it! thanks, i really missed the subsequent alterations needed, this script is amazing! great work

this should be release as Kicad6 plugin package!

[whitequark]

this should be release as Kicad6 plugin package!

I don't know how to do this.

[sabogalc]

Idk how to publish KiCad add-ons either but would this help? https://dev-docs.kicad.org/en/addons/

[whitequark]

That does help, thanks.
