Lemme jump in here and answer my own question. CHSPACE command.
If I can set up a scale for my stuff in modelspace, I can place a section mark, for example, on an edge of my part in modelspace, at a specific scale, then use the CHSPACE command to move it from modelspace to paperspace.
I'm now rubbing my hands together and twirling my handlebar moustache...
Oh, and ... uh ... Thanks, Lynne Allen.
