Gerber error, big concentric circles

[Leonel Caraccioli]

Two chinese PCB Manufacturer (using Mentor) report that the Gerber files (made with KiCAD 5135) display severals bigs circles.

I use others Gerbers viewers like http://www.gerber-viewer.com/ and there is no problem.

I don't know wath is happend.

I attach a PCB file, gerber files and jpg send to me by the Manufacturer.

Please take a look at this thread on the mailing list https://lists.launchpad.net/kicad-developers/msg15214.html. If this is the same problem that you are having, then it's a problem with your board manufacturer's CAM software. If not, please let us know so we can fix the problem.

stambaughw: Yes, thanks. I tried the solution proposed by Mark Roszko changing:

void GERBER_PLOTTER::Circle( const wxPoint& aCenter, int aDiameter,
FILL_T aFill,
                              int aWidth )
{
     Arc( aCenter, 0, 3600, aDiameter / 2, aFill, aWidth );
}

into

void GERBER_PLOTTER::Circle( const wxPoint& aCenter, int aDiameter,
FILL_T aFill,
                              int aWidth )
{
     Arc( aCenter, 0, 1800, aDiameter / 2, aFill, aWidth );
     Arc( aCenter, 1800, 3600, aDiameter / 2, aFill, aWidth );
}

in kicad_sources/kicad.bzr/common/common_plotGERBER_functions.cpp

Now, I'm waiting for manofacturer results.

I found this thread after post this BUG.
