Hi all,

I've implemented two major features in the parametric footprint support in 
pcb-rnd (and in the online version).

The preview tool, fp2anim, can display dimensions on the annotation layer. 
This is useful for checking whether a footprint really matches the 
datasheet. Details: 
http://repo.hu/projects/pcb-rnd/devlog/20150820a_dimensions.html

The more important feature is a new class of footprints. There is a low 
level, generic, but complicated to use qf() which should be able to 
generate anything that has evenly spaced pads around a rectange.

There are frontends to qf(), called qfn(), tqfp() and lqfp(). These 
generators are very easy to use: they have only a few parameters, those 
that are usually specified among the first lines of a package datasheet. 
They can't handle special cases, but can safely generate any of the usual 
QFN/TFQP footprints. Details: 
http://repo.hu/projects/pcb-rnd/devlog/20150820b_qf.html

The online version of the parametric footprint generator is accessible at 
http://igor2.repo.hu/cgi-bin/pcblib-param.cgi

The source is in svn: svn://repo.hu/pcb-rnd/trunk/pcblib/parametric

Comments, bugreports, feature requests are welcome.

Regards,

Igor2
