The program already has a 3-Tier library system that you could move up to. Since there are no 3-Tier solder joint goals for BGA, CGA, LGA and now ALL components smaller than 1.6 mm now have the same solder joint goals (1-Tier), the only difference from switching to Least, Nominal and Most environments is a Silkscreen Rules for Line Width and Pad to Silkscreen gap. I can give you a free webcast to show you how to set up your personal "DefaultPreferences.dat" file for a 3-Tier library system, but I think you want something different. You want to change the Silkscreen Rules at the "Terminal Preference" level. That would be a huge programming effort. Or perhaps you just want to adjust the silkscreen outlines for - - Parts less than 1.6 mm
- Parts less than 1.0 mm
- Parts less than 0.5 mm
- Or maybe just 1 rule for all parts less than 1.6 mm is more reasonable
I'll discuss this with the programmers but they already have a product roadmap for V2014 - - V2014.07 - Add complex user defined pad stack creation in FP Designer (August)
- V2014.08 - Add the "Slider Calculator" component families (August)
- V2014.09 - Bug fixes (no new features) end of V2014 development (September)
- V2015.01 - Introduce a new FPX file structure that can save custom data (October)
- V2015.02 - Add lots of new features (November)
- V2015.03 - Add interactive graphic editing to create unique footprint pad shapes and outlines (December)
I'll see what I can do, because I support your concept, but by looking at the roadmap, V2015.02 is the place where this new feature would fit in. In the meantime, I would create my parts less than 1.6 mm and in the Calculator Drafting tab I would change the silkscreen rules "on-the-fly" build the miniature footprint and be done with it. i.e.: build it once, build it right and never build it again. I would also create a new FPX file just for all parts less than 1.6 mm so if I had to batch create them, I have a "MiniPartUserPreference.dat" file that has the rules you want for that group of components. It's a workaround that would work well for you for now.
