I don't have help for you, but maybe I have help for him. If the reason he won't use schematic capture is that he thinks optimum placement and routing is achieved by placing and routing, then figuring out the schematic later, I have a suggestion for him. I have had to do something like this before, where placement and routing dictacted all else. I did it by designing a tentative schematic first (with netlist), routing the board, and then changing the schematic to match the board. Many changes were required, but it was still worth the effort. It was a bit of "tail wagging the dog", but was necessary due to extreme placement and routing requirements. This was tougher to do back in the days of v2.8. It should be easier now with 99SE synchronizer.
Is he using non-netlist-aware layout software? As I recall, PCBExpress gives away free software that can be used to lay out double-sided boards, but it is not netlist-aware. So I don't think you could generate a netlist from it, unless you generate it from Gerbers.

Has anybody out there ever have to upated a schematic's reference designators based on a PCB layout, when there is NOT a netlist to back annotate. I have to clean up an engineer's schematics, and he refuses to use an inteligent schematic & layout. He just places the parts on the board and wires them up. Not only does this create a situation where I have to clean up the schematics (Ref Des's; missing or incorrect parts; wrong connections, etc.), it is also difficult and time cosuming to go back through the board and assign our company's part numbers.
