Hi Tom, I fixed this issue in rev 2c56085f410d75ad2b01164b12d9dee95c7d3ab6 In fact I found 2 problems: 1) DRC::checkMarginToCircle() detected a DRC issue for dist <= clearance, instead of dist < clearance 2) In DRC calculations, calculations create rounding issues (this cannot be avoided) So, to avoid false detections, the detection is now dist < clearance - 1 nanometer. Please, try this rev. FYI, the current clearance test algorithm is quite complex because it was optimized in the early times of Kicad, when computers did not always have a FPU, and were slow. It could be now certainly less complicated. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
