Old topic I know, but I've just added the bits mentioned by Richard to my
eagle.def but now I'm being asked for wheel files - when I give it
glaser.whl (the only wheel file I could find), it then complains of missing
apertures. How can I get gerber output in metric without all this wheel
melarkey...when using imperial, I just use the GERBER_rs274X & fon't get
prompted for wheel files or have apperture missing type errors?
