Stair Landing w/ two stringer profiles

[ndsmaug]

I have a stair by component where the left stringer profile and the right stringer profile are different.  The landing, however, will only apply the right stringer profile, and it does so on all 4 of its edges.  I can delete the profiles I don't need, but I can't find a way to apply the left profile to the left side of the landing.  It will only apply the right profile.  If I delete the profile it applies on left and try to add a new one via the "Support" button, it again only applies the right stringer profile.  

Anyone have a "fix" for this?

Thank you!

Do you have a sample file or image to help illustrate? I tried to reproduce the behavior (2016 R2), but the left and right stringers applied around the sides of the landing as expected. Maybe we have something set up differently.

It's hard to tell, but in the image you uploaded it looks like you are using the same stringer support profile on both the left and the right side of your landing. What I have (using Revit 2015) is an intermediate landing on a single direction stair (not a double back like the one you have) and using the support button, it will only add the setting for the Left support.  What I need is for it to recognize I have a left and right condition, therefore the Right support should be an option.  It is not.  As you can see in my shot below, I have a 12" wide stringer for the Right side and a 6"wide stringer profile for the Left support.  Using the Support tool, I am allowed to add supports on all 4 sides if I so choose, but it will only be the the Left support.  I never get the option to change it.   This was what ultimately lead me to just delete all the stringers from the stair and landing and just model them in place as a Railing support.  Hopefully my image below illustrates what my problem is. 

Thanks.

I did have two separate profiles in my last post, but that picture doesn't show it well. Instead I tried to reproduce with your setup - a 6" width and a 12", and I was able to have both as expected on the landing. Do you maybe have a small sample file? 

[kathryn.langan]

I just wanted to check back in to see if you had been able to produce a small sample file to look at, or if you can see from my screenshots whether there is something different between how I'm testing and how your stairs are being created.

I've come across this issue as well where I've programmed one side with a 3" tube steel stringer and the other with a 4" tube steel stringer. For whatever reason I cannot comprehend, the side I need to be 4" tube steel has two lengths that are 3" tube steel around the larger of my two landings.

You can see where the blue outline jigs in the left left corner of the elevator.

I don't understand your description. Are you saying the Stringer diameter is not what you expected (e.g. 3" vs. 4")?  If so, have you verified that the Profile assigned to the Stinger is correctly drawn in the family?  

Also, you can post the RVT here for us to examine.  

[pgiddings]

Correct. From where I circled onward, Revit modeled the 3" stringer instead of the 4" stringer when the settings should be assigning the 4" stringer. There are 7 stringer elements and 5 modeled correctly as intended.

I double checked both profile families and both were correct. Is there a way to edit stringers on an individual basis instead as a left and right function through the stair edit? Or is there an independent location to edit the landing's stringer because that is where the issue occurs.

I exported the stair in question to a separate model. Please see attached. Thanks!

This problem still excists in Revit 2022. Why isn't there a solution yet? Match Properties should just work on stringers, both on runs and on landings.

I'm having the same sort of problem here in Revit 2023. The design is calling for C10x15.3 left & right stringers for the stair, and C8x11.5 stringers around the landing, but for some reason it won't let me change the landing stringers. I can change the stair stringers, but everything is grayed out when I try to change the landing stringers. Anyone know a solution to this?

[barthbradley]

How are they connected?  

[donne.puckle]

I didn't add any connections to the stringers. I just drew the stair and landing using the Stair tool under the Architecture tab. Earlier, I had drawn a stair and platform system by setting up the stair first, and then drawing the landing separately using beams (not using the stair tool). We're trying to find out whether we can use the stair tool to draw the stair and landing together, and then have different stringer sizes for the stair and landing. Unless I'm missing something, it doesn't look like Revit 2023 gives me that option.

I was asking how the C10x15.3 stair stringers are connected (e.g. attached) to the C8x11.5 landing supports. I see it as completely separate constructs.  Hence, I would model it that way - as I did in my screenshot above.  Unless you are meaning that the C10x15.3s make a contiguous transition to C8x11.5s around the landing and then transition back, contiguously, to C10x15.3s.  I don't know. That's why I asked for additional info.
