Hi,I am using Revit 16I have problems modeling af precast stair with notch connections on both sides of the landing. There is 2 pictures attached "stair 1" and "stair 2" "Stair 1" shows how i wish the connection should be."Stair 2" shows how I manage to model it. The stair shown on "stair 1" is made as a generic model, which makes alot of problems.The stair goes from basement to 2nd. floor, the stories have different heights.Can anyone give a hint on how to model this stair?I will be grateful f anyone can help me with this.

We would never model this connection. it would only be in the details.   We would use the normal monolythic stair and landing.

Stair 1 (your preferred) looks like a Precast Stair using a “Notch” join and with “Begin with Riser” and “End with Riser” cleared. Is that not correct? What do you mean by “[it] makes a lot of problems”?

Hey,Thanks for your reply - I first noticed your reply recently."Stair 1" is made as a generic model - Which means its made as an extrusion. Somebody has been busy editing the profile of the whole stair. There is grips on risers and goings. So there is a lot of manual adjustmens to get the right result. We also have problems making it a host for ralings.Modeling the stair as a "precast stair with notch connection" I dont manage to get the notch connection on both sides of the landing(s) as you can see on "stair 2"As an extra challenge I would like to model the coving as well.Is that something you think is possible?
