Good morning.  I am a relatively new printed board designer who unfortunately 
is unable to get a straight answer out of anyone here.  We are currently using 
Cadstar For Windows 2.2.2 to design our boards.  After the layout has been 
approved by everyone, we view the spool files before sending them on for 
prototyping or release in Cam350 or ECAM (depending on who has the key).  We 
currently import the spool files and convert them using RS-274.  We have the 
option of using RS-274-X though.  Could some kind soul explain the difference 
to me?  No one here can - we are all just winging it.  When I ask, I'm told 
"That's the way we've always done it."  I refuse to accept that as a valid 
reason.  No one here *ever* uses the IPC standards even though we do have a 
copy of some of them on hand.  (Scary, ain't it?)

I'd really appreciate some straight answers from others in the industry.  My 
boss keeps saying "But the boards work.".  Surely they must be  a better way 
and a more intelligent answer to my questions.

Thank you
