Yes, I found it - but the lines look so different to this I would expect.You can miter the corners afterwards with the "Miter" option in the Connections menu. Doing that prevents the optimizer from working, though, as it only supports right angles.
I can see the clearence between the pads and the filled area in PCB, but If i print out the file to gerber - then the filled area is without any clearence and produces shortcut over all pins/pads?
What are you viewing the gerber files with?
I think it is gc-prevue under windows. Do you think, it could depend on the viewer? The other gerber-printouts without filled areas looks fine. I've got the feeling, there are two problems with filling areas: 1st. Auto-router is not able to produce lines which clears polygons 2nd. a problem with the gerber-generator using filling areas?
