Silkscreen questions

arcwilson

I've finally finished my first layout in PCB Editor (whoo!) and I'm trying to generate the artwork files, but I'm having some silkscreen issues.

1.  I'm trying to use "Manufacture->Silkscreen.." to generate the Autosilk layers in the Manufacturing class, but for some reason it copies everything from "Package Geometry/Silkscreen_Top" EXCEPT a logo that I imported using Dave Elder's logomaker skill (which is fantastic btw!).  When I check the info on the logo, it all its shapes show "Package Geometry/Silkscreen_Top", and I've set the Auto Silkscreen options for Package Geometry to both Silk and Any, but still get the same results.  Is there something I'm not understanding about how Auto Silkscreen works?

2.  The second question I have is whether there is a way to set the silkscreen line widths for a layout on a global level, instead of pre-defining them within the individual package symbols.   For example, create all library symbols with a silk line width of 0, and then once the symbols are placed in a design, define a global silk line width for the entire design.  

 Once again, thanks for the help.

    Hi Chris,

    1/ Another of my utilities (in widespread use) handles this and other issues with silkscreen.
    Look for autosilkUtils.il (http://sourcelink.cadence.com/docs/files/SKILL/Allegro_SKILL_Code/autosilkUtils.il)

    2/ That would be relatively easy using Skill. I don't know whether you could do it easily otherwise.

    Cheers, Daev
