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.
