I understand the value of an assembly drawing. I was just pointing out 
that it probably should be separate from a fabrication drawing (which is 
what DJ originally announced).

If you do all of your assembly in your own laboratory, it might make 
sense to combine the two. But a board manufacturer doesn't need to know 
the values of the components that will be stuffed, and when you're 
stuffing components, you probably don't care about drill sizes.
