Hello,
I'm trying to figure out if there is a way to make the stair tool construct the following stair shape and type (see images). I can make this stair using the precast stair type in sketch mode, but where I'm struggling is the underside shape of the treads. The proposed design is to use blocks of cut stone layered on top of each other. The underside of the stone is slanted as you can see in the hand sketch. We can build this out of generic models but I would love to be able to take advantage of the actual stair tool for documentation purposes. We are using Revit 2022 for this project. Any suggestions appreciated!
I would use details to clarify the tread profile and keep the 3d stair simple for plan / elevation dimensions.
Yeah, I understand this approach but would like to use the model for 3D presentation purposes, given how we work in our office. My only other options for this would be using generic models to build this or bring the whole thing in from Rhino, which is what we usually do with complex stairs. Also, interior elevations of the stair hall would be almost more complicated to draw out in detail lines than to actually model it, given the elliptical path of the stair.
Create the Stair Treads as Balusters with the Railing tool. That's probably what I would do if I had to model them.
Interesting, I'll look into this. I was also wondering if there was a way to game the stair tread profile setting in the stair tool to generate the shape? not sure how that would work.

Actually, you should be able to do the Treads with this Profile.
Have you tried?

Tread profile won't work when your tread depth varies within each tread (circular, winder, elliptical stairs).
That's why I haven't tried it yet....figured that would be an issue. I also wasn't sure how that would integrate with the actual stair since the tread profile is applied onto the precast.

If you have rhino an know how to use it then model the 3d stair in rhino and link in for 3d/elevation/section; and keep the simple Revit stair for plan presentation. You can even export the simple Revit stair to DWG and import it in Rhino for a skeleton to start modeling from.
For the sake of the model, I'll probably build the stairs native Revit using generic families or in place modeling. Rhino imports don't always behave. The railing and balusters will be coming from Rhino anyway, Revit can't handle those, at least the way that we design them. I've been using Revit for 20+ years, the stair tool has come a long way since then. Sometimes I get surprised by capabilities that were integrated over time that I didn't know about so was hoping that maybe I was missing something.
Here is a stair done in Rhino and linked in Revit for 3d presentation. No way I could or should have done it in Revit.
Sorry for lag in response...yes, that's it! Did you use the stair tool or something else? Also, the stairs to slightly splay out as they go around the ellipse, so I don't think a swept profile could work.

I was only showing that your tread profile could be used, but no; it can't "splay". It can only extrude. As I said before, if you absolutely have to model the treads that way, you can get there by using the Railing Tool - assuming you can replicate the tread. Obviously, if every tread is unique, that wouldn't work either. But, based on what I'm seeing in your screenshot, it looks like Railing would work. A lot of work though.
