Hello All,
I am running the gEDA version that came with Ubuntu 11.10. I have two
questions:
(1) Is there a way to make vias less than 21mil across? Currently, I
have declared a 10mil drill hole, but even if I make the drill hole
smaller, say 5mil (this is just hypothetical; I am not going to order a
PCB with 5 mil via holes), gEDA still refuses to let me decrease the
copper diameter to below 21mil (5½´´ thickness of the annulus). I would
like a copper diameter (via size) of 18mil. I cannot figure out why PCB
refuses to let me go below 21mil. Commands like
'Changesize(selectedvias,18,mil)' do not work; they only work when I
want to increase the via size.
(2) I am laying out a board where the layout is very tight. There is no
room for REFDESes. However, I will need the REFDESes in the printout of
the layout because the board will assembled by hand. I would like a way
to turn the REFDESes on the PBC selectively on and off, so when I print
the gerbers to send to fab house, the REFDESes which take too much space
will not show up, but I can still turn on the REFDESes at a later time,
when I print the layout at some magnification. The silkscreen contains
some items I would like printed on the actual PCB, so it is not an issue
of turning the silkscreen on and off. I manipulated the PCB with vim,
turning all REFDES sizes to zero. Unfortunately, PCB printed little
blobs on the silkscreen then. Any ideas?
Thank you in advance for your time.
