Ah ! ! !  Yes ! ! !   the ol'  ...CLEAN 5 ... FILTER 2 ....CRITIC 
   routine,    but it still takes the finesse of the a fine- tuned puck hand 
to  ...BUMP ...SLIDE ...PUSH ...SHOVE     or whatever the infamous commands 
on your particular CAD Tool is ...to balance out the aesthetic and 
manufacturabilty of the design.  My  "WISH"  is that the CAD Tool would do 
want I want it to do ..instead of what I do with it.   I have often  , in 
the dead of night , held a copy of IPC-D-275 to the screen of my system in 
the hopes  of 'absorption by osmosis' of some better DesignRule guidlines 
...but long gone are the times when you had all the pinouts of every DIP 
device in the TTL books memorized and all you needed was a sharper pencil to 
get that one addition line in there.  Now we answer  not only to the E.E.'s 
 , but  also the M.E.'s , the MFG. E.'s , the ICT  E.'s  (test) ,  the Assy 
E.'s , "The Fabricators" ,  Purchasing  and sometimes it seem like even the 
cafeteria personnel and maintenance are getting their 2cents in on our 
designs.  I feel that CAD Designers have become far more 'Multi-Tasking' 
than alot of the CAD Software that is out there.  Our task has become to 
make it work despite all of the limitations written into the 
software.....along with becoming a part-time LAN -- SuperUser -- ROOT -less 
 (no root privileges) HardWare expert.
                                              WOW !
