   The physical dimensions of the _drawing sheet_ when printed out at its 
intended size.  An 8 1/2 x 11 piece of paper is A-size, an 11 x 17 is B-size, 
17 x 22 is C-size, and so on.


I believe the page is supposed to be 11x17, but I'll talk to Howard about it.

   If the schematic shows only the parts mounted on the board, it's a board 
schematic.  Most PCB design flows require a schematic that's specific to the 
board.  If the final assembly requires electrical parts that aren't laid out on 
the board artwork, the board would normally be a subassembly, and the board 
assembly would be listed as a part on the final assembly parts list.  (We can 
talk about assembly trees and other drafting terminology later; I know you're 
busy.)  Is the OGD1 a single-level assembly, with no subassemblies?


I believe there are no subassemblies.
