Problem changing text ratio in library parts

autodeskguest

Hi Eagle support.

 

I have designed a board in Eagle 4.16r2, and was about to send it for

manufacture when I spotted that my target manufacturer (Olimex) requires

all silkscreen lines to be at least 10 mils.

 

So I'm trying to update all my packages to use 10 mil lines.

Olimex recommended for text to use 50 mil size with a 20% ratio in order

to get the right line width.

The trouble I'm having is:

1. Clicking Change->Ratio opens a dialog, I type 20, Enter.

    Then when I click on the existing text, it stays at 10%.

    It seems that the only way to fix this is to delete the text and

    re-enter it starting with the right width. Is this an Eagle bug?

 

2. Quite a few of my board symbols are smashed, so that I can move the

names to more convenient places. Unfortunately once smashed, it seems

the text cannot be updated to the right width when I follow step 1 above.

 

Please can you help, as it's currently driving me crazy!

 

Thanks.

Steve.

 

  • OK, quick update on this issue.

    The ratio can be updated, but only if I also switch to vector font

    instead of the default proportional one.

     

    I have another self-inflicted problem now, as I was foolish enough to

    use a ULP from Olimex to "fix" my silkscreen widths. This seems to have

    simply cloned all lines / text in tNames, increasing the width in the

    process. It also means that if I try to move a symbol (or change text

    properties) that the cloned lines stay behind and litter the board!

     

    I had convinced myself I had backed up the board before running the ULP,

    but now I need it (a few days later) I can't find that backup.

     

    Is there any way to purge my board of any lines / text that are not part

    of a package? My hope is that by doing this, I'll be left with the

    original package drawings and text, that I can then go back and fix

    manually (properly) in the libraries.

     

    Ho hum, short-cuts never are, are they?

     

    Steve.

     

  • board houses generally do not print the proportional font as it can't be

    represented in the Gerber files. to avoid nasty surprises when converted

      into vector font, you should always use vector font on your silkscreen

    and copper layers.

     

    in user options or preferences or some such dialog, you can force EAGLE

    to use only vector font on your layout ( and keep proportional in your

    schematic if you prefer ).

     

    as far as your corrupted texts, if they are on the same layer as the

    ones you want, you could try looking for your backed up autosaved files

    and find one that didn't have those changes. but i would just delete

    them manually. it may also work to smash all, delete everything on the

    layer, and then unsmash all to recreate the labels. but you would lose

    the positioning...i'd just delete them.

     

    as one who mistakenly sent a proportional silk screen to a board house

    and received labels in all the wrong places, i advise you to avoid this

    mistake and make sure everything on your layout is vector font...

     

  • Ah ha! I had been looking for an unsmash option but hadn't figured it

    out. RTFM and of course it's there - hold the shift key.

     

    Thanks.

    Steve.

     

  • yup, took me a few months to find it, finally searched the manual in

    desperation...
