glennw: I like that ramp idea. never though of that before; I'll give it a try!
Russ: My typical approach is to make sure that the framing, stairs, landings are finalized. Then, in a section view, I draw a CAD line along the nosings, and replicate it vertically for each rail and convert those line into 3D molding polylines to get exact appearances correct. I'll place one spindle and replicate it on the correct coordinates after I've calculated the spacing. The key is to keep adding every custom made molding to your library so it's easily available for any plan. Is that in any way similar to what you'd do? Or anyone esle, for that matter?
