I am trying to draw auditorium risers. The simplest way would be to draw a profile which is the section of the seatin risers then extrued if from one plane to another (angled) plan. This doesn't seem possible with revit. Or create monolithic stairs & draw by boundary. That doesnt seem to allow specifying a fixed riser and tread dimension (in this case 10" riser, 3' tread). Any ideas?

Easiest way to be accurate would be to create an inplace family, however that said it could also be done using monolithic stairs. Yes you can't specify the riser height persay however if you tell it to riser a certain height and have the appropriate number of risers, revit will set the riser height to the correct height. Tread lengths can be fixed, they're set when you draw the sketch for the stair.

The commands are
[1] open a new drawing file / new / family / generic model
[2] in front elevtation view (????) draw the section of the stair risers
[3] name and save it
[4] back to original draiwing:
[5] file / load from libr. / load famil / load it
[6] modeling / component / create in place [button] / [pick] floors / solid form / solid extrusion... then what?
I want it go go from one plane to a another. The two planes are oblique - see pdf attached to original thread. How do you do this?
Also if I try to do a monolithic stairs from level x to level y, it forces me to choose a desired # of risers, the "actual riser height" is grayed out. I set the "actual tread depth to 3'-0". I can draw by boundary, draw the risers and it comes out all wrong
I just want (exactly) 12 risers, 10" riser, an (exactly) 36" tread. No can do.

Your desired number or risers is what revit uses to caculate the riser height. ie: Level to level height/Desired no of risers. The actual number of risers is greyed out as its defined by your sketch. Remember your drawing risers and boundaries in your sketch.
To get the numbers you want. Draw 12 risers, set the desired risers to 12, space your riser lines out by 36" and you levels set up so that the stair is 120" high...
Not sure what your doing with the family thing.
1. setup a section parallel to one of the end faces (this is to enable you to draw your profile accurately.
2. Modelling tab-->Create-->Floor-->Name it (ie: auditorium floor)
3. solid-->Solid sweep (in plan view)
4. Draw your sketch for the path. Just follow the arc of one section. Remember you can have it continue all the way through and then we can use voids to break it up where needed.
5. Move the profile marker (reference plane located along your sketch, usually at the midpoint of the first line) by dragging it to the start point of the arc making it parallel to your section.
6. Finish Sketch, Sketch profile. Your asked to go to a void that will be seen on an angle, pick your section (it should be in the top list if its parallel, if not you haven't created exactly right).
7. Draw your profile.
8. Finish Sketch, add voids if needed in plan to break the sections up.
9. Finish Family.
Note: you can now attach walls to its underside.
HTH.

Thank you for that lucid walk thru. All this time I've used revit - I didn't see the "create" under modeling. See attached. Attach walls to underside of the solid works as you said. Making the extruded solid works better than a "stair" since not all risers & treads are actually the same (aisles, etc) Thanks.

Having completed that, how do I draw railings that follow the slope of these?

Hmm, railings can only be hosted by floors, stairs and ramps and i don't think they'll host to the in-place floor. You could give it a try as i've never tested it. Just use the set host option in your railing sketch.
Otherwise, if this doesn't work (are you using worksets?) as you would need to create an invisible stair to host the railings. You could then turn the stair off by setting it to a workset that is by default off in all views. Or you could just have a stair that only is basically the tread thickness and just gets embed in the created floor and host them to that...

I am just going to show the railings as glass walls that I can edit --> profile to make follow the slope of the risers. Thanks!

It seems if you create floors there is no way to create a color fill legend that will show up without turning off the floor visibility. Of course that would normally be no problem, but now that I have an inplace floor family which consists of the whole room (the risers) only that one sanctuary room is not color-filled. A way around this?

Could paint the floor with a material of the appropriate colour...
Floors always block colour fills regardless of there in-place or not. Which is why when placing a colour fill it prompts to turn them and topography off.
