or add a new size option to an existing one ? 2014-05-12 12:12 * wpwrak notices that it's very hard to get people to try fped. once they've used for a few minutes, they love it. but getting them to make the first step is nearly impossible. 2014-05-12 12:21 same as with heroin 2014-05-12 12:28 if you look only at similarities, almost everything is the same 2014-05-12 12:31 wpwrak: making the footprint larger inside PcbNew ..if it works out than will create a new module with different footprint 2014-05-12 12:31 heroin, the universal similant. now there's a new thought :) 2014-05-12 12:32 nicksydney: are you using footprints from the kicad libs or from qi-hw' 2014-05-12 12:32 s kicad-libs project ? 2014-05-12 12:32 wi0h 2014-05-12 12:32 qi-hw 2014-05-12 12:32 then you already have the original in fped 2014-05-12 12:33 you're using iunductor-2p-3mmx3mm ? 2014-05-12 12:34 yeah 2014-05-12 12:34 try cd kicad-libs/modules; fped inductor-2p.fpd 2014-05-12 12:35 see the nice little table ? :) just has one row at the moment, but there could be lots and lots more :) 2014-05-12 12:35 size{x,y} is the component size; p{x,y} is the pad size; gap is the space between the pads 2014-05-12 12:35 http://postimg.org/image/bep50rokz/38b232d4/ 2014-05-12 12:36 move the divider to the right or increase to full-screen 2014-05-12 12:36 ok i've increased the px and py 2014-05-12 12:37 but it did not chnage 2014-05-12 12:37 did the background turn blue ? 2014-05-12 12:38 px turns to magenta 2014-05-12 12:38 and at the bottom there is a green bar where i can enter the value 2014-05-12 12:38 http://postimg.org/image/n2p95zbz1/574ef59f/ 2014-05-12 12:38 yup. don't forget the mm 2014-05-12 12:39 ahh ok 2014-05-12 12:39 it works 2014-05-12 12:39 if you forget the unit, then it prints an error in the status line at the very bottom and the background of the drawing turns blue 2014-05-12 12:39 (and it doesn't update the drawing) 2014-05-12 12:40 so once i save it ...and go back to kicad it will refresh ? or any other steps i have to do ? 2014-05-12 12:42 naw, don't change the existing entry. else you'll lose the old footprint. 2014-05-12 12:42 quit, restart, and make a new row instead. 2014-05-12 12:42 or is your inductor 3mm x 3mm, too, just differing in px/py ? 2014-05-12 12:43 what's the part number anyway ?
