As I have access to commercial Gerber Tool at work, I recently did some tests for importing diffrent Excellon format precision into GerbView: 7+8 digit formats (seems possible but no standard (???) and) are not detected automatically by GerbView. 6 digit formats 3.3 or 2.4 or 4.2 always import correct with or without leading zero supression or step&repeat. Another thing I found, that the (old header) G81 FMT1 instruction generates error message while G05 FMT2 equivalent does not (but both behave well). If anybody is interested in test file data I can dig for them or generate new test files
