Can you sketch this monolithic stair? I couldn't.

How can this stair be modeled in Revit using the stair sketch? I want it to be 21" high. I do not want it to include the porch platform. I've tried everything I can think of. Then I just punted and used the component model in place with a predefined profile defining the three step edges as a sweep profile and and extrusion as infill.

Actual In-place stair

The in-place method doesn't suffice?..

Plenty of approach: model in place with sweep profile like you did; floor with slab edge; stair. Here's using Stair tool.

What's wrong with assembled stair?

@martijn_pater Here is the result of the component method using sweeps and adding a material. It takes longer but it works.

@barthbradley , When you say assembled, do you mean using the stair sketch tools or modeling in place? If you sketched it, I would sure to know how you did it. Your stair looks good.

@ToanDN I literally tried for 4-6 hours trying to use the stair sketch tools and fiddling with the monolithic nosing settings. Couldn't get anywhere. It kept either refusing to make the stair or when it did, the stairs had odd artifacts and sloping treads like it sliced it off with a knife. Your stairs look good.

Yes I used Assembled Stairs. Edited properties and unchecked Riser and changed the Tread Thickness to 6 171/256" (the Actual Riser Height). Then added my Brick Nose and changed the Material of the Tread to Brick. Bada Bing!

Oh! I forgot. I deleted the stringers as well. You could also change the Properties to omit the Supports (e.g. set to "None") as shown:

You could also do it this way -- with the Riser and Tread the same thickness as the brick unit:

Thanks. I will try to repeat those techniques this evening.

Okay, sorry for hogging your thread, but I got one more for you.

Using a Support for representing the foundation under the brick:

It's a few simple settings to a monolithic run.

Thanks @barthbradley . Sketching an assembled stair that looks monolithic is a lot more reliable than sketching such a stair as monolithic.

You're welcome, Doug. Thanks for the shout out.
