Gerber Export: incorrect filled areas outline thickness

[Thomas Wischnack]

Gerber export with Pcbnew. Load gerber files in Gerbview. Gerbview complains about "missing D Code definition; perhaps old ...". Checking Gerber with external gerber viewers shows same result; wires/tracks/copper areas with wrong thicknes.
Problem exists only in some gerber files; always the same within one project, but not always the same file in different projects. Problem exists in all projects.

Please, send us a board file that exhibit the issue and the broken Gerber file.
Thanks.

[Thomas Wischnack (dl3it)]

here we go... board-file and generated gerbers... one critical layer is e.g. .gtl

[jean-pierre charras (jp-charras)]

Hi Thomas

the .gtl gerber is OK, works fine, and has the aperture list (DCodes).

The only 2 files that has not dcode are Power-F_Mask.gts and Power-F_Mask.gbs.
But this is OK because it contains only polygons (Regions in Gerber).
Gerbview complains only for these 2 files, but this is a overzealous complaint.

[Thomas Wischnack (dl3it)]

Hi Jean-Pierre,

I added 3 screenshots.
- Kicad: what it should like
- GerbView: check e.g. lower right corner; all planes mix togheter
- JLCPCB: same as GerbView

Maybe this explains a bit my findings and my assumption that the error message comes up is missleading me. The version from yesterday gave results as expected, and no error message.

[jean-pierre charras (jp-charras)]

OK.
There is an issue related to filled zones.

Hi Jean-Pierre,

i have built kicad on my own, hopefully including your fix. Seems to work again as expected.
Thanks for the quick fix :-)
