The fab will cut the board > at the center of the lines. Is this universally true? At least our milling machine mills the outline on the outer edge of the lines. The guy who runs the machine says, he cannot easily tell the programm to mill along a center line. I prefer to keep the line width within tolerances to both sides, so if the fab ignores my README specifying the centerline, it is no big deal. -- Stephan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: gerber outlines
So if in preferences I set the board size to 1550 x 1550 and draw on an outline layer a 1500 x 1500 outline the board size will be 1.5" x 1.5"?

No. You need to add an extra outline layer, which is empty except for the board outline, which needs to be drawn as a closed seqence of lines (and/or arc?). > I then exported the gerber file and the outline gerber still shows nothing. > The help link above makes it sound like PCB will generate the outline > automatically to the 'outline' layer absolute edge. No such automatism. > Do I have to draw these lines in or does PCB do this and what should I see > when viewing the outline gerber layer? Yes, you need to draw them. The fab gerber includes an outline trace, which is the 'absolute edge' of your design when there is nor outline layer. -- Stephan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: gerber outlines
That's the way to do it. Try checking the "all-layers" option. Also, watch out for spaces or capitalization in the "outline" name. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: gerber outlines
I'm trying to provide Dorkbot PDX with gerbers for a two-layer circuit board. They require an outline gerber so I followed the [1]http://geda.seul.org/wiki/geda:pcb_tips#how_do_i_make_a_board_outlin e_to_go_with_my_gerbers_to_the_board_maker instructions by naming the active layer which for me was the component layer 'outline'. I then exported the gerber file and the outline gerber still shows nothing. The help link above makes it sound like PCB will generate the outline automatically to the 'outline' layer absolute edge. Do I have to draw these lines in or does PCB do this and what should I see when viewing the outline gerber layer?
