Bug Description

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.

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

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.

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.

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 :-)
