Any gerber experts out there who know if the below is valid rs274x? The thing I'm worried about is that after the G74 there are linear interpolations, but there's no explicit return to linear mode from the previous G75 circular. Gc-prevue displays it as it's meant to be, but gerbv doesn't. If I put a G01 after the G74 then gerbv and gc-prevue both display it ok.
In rs274xrevd_e.pdf it says "G02 and G03 specify single quadrant (90°) circular interpolation; G74 disables it.", but I'm not sure what this means (disables what?). So is this a bug in gerbv, or an ambiguity in the standard, or is it sloppy gerber which gc-prevue can cope with? *%FSLAX24Y24*% *%MOIN*% G01* %ADD17C,0.0080*% %ADD25C,0.0500*% D17* X275095Y118850D02* G75* G02*X274966Y118923J150D01* G74* D25* X286281Y117619D02* X286764D01* X286764Y117629D02* Y122729D01* X283784Y122729D01* X283784D02* X281763Y120709D01* M02* -- Peter Baxendale <[EMAIL PROTECTED]> _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
