i've always wanted a 'drc style' command, like 'extract style'. then the techfile could have sets of drc rules, with some 'quick and dirty' (like basic widths/spacings) for large cell interactive editing and some that are more complete for later full drc'ing, and one for the extremely slow cif drc commands. /jeff R.
