Landings on Multi-story Stairs

[myBIMhero]

We are trying to get in multi-story stairs for 3 floor building. It is a metal deck stair system already existing. I cannot get it to place a landing at the floor level in between each set of stairs. Nor will it place the railing when it reachs the top of the floor and makes a ut turn to go up to the next floor. It does the railing and landing at the intermediate level but not at the floor level. I tired to build this as one set instead of a multi-level but the railings are a nightmare. Any ideas? Thanks!!!

Please post an image showing the results you are getting now.

This is it in its most masic form. I tired extending the boundary to get a landing at the 2nd and 3rd floor but got all sorts of errors. Thanks. I want there to be a landing at the 2nd and 3rd floor just as the intermediates are. Also the railing to be continuous. Not sure how to make this happen on a multi-story. I tried to build it as one stairway going from 1 to 2 but the railings got all screwed up.

[Alfredo Medina]

Wouldn't the "landings" be the slabs themselves? Why would you need a landing at 2nd and 3rd level? Isn't there a slab at these levels?

[myBIMhero]

This is what happens when I create it as a single stairway from floor 1 to 3. The railing gets messed up and still miss the top landing.

It is a free standing system that sits just in front of the floor slab. My thinking is that I may have to just use the floor slab. Either way, I cannot get the railing to wrap around.

You'll likely need to create a floor of the type that the other landing is based on and insert it at each level. Then you will need to create a separate railing that finishes the continuous portion at each level.

What you're wanting to do is made difficult (if not impossible) by the realities of how Revit creates railings. The sketch lines cannot be overlapping or in a continuous loop, but when you have a stair that does just that, you must break the railing into multiple sections for it to work.

This type of stairs is not possible in Revit yet. When you are doing the sketch for a U type of stair going from Level 1 to Level 3, when you draw the first flight and then make a U turn, draw the second flight... (Here is where I should be able to tell Revit, hey I am on the second level, allow me to overlap lines to go to the third level) But, no there is no way to tell Revit that I want the other two flights overlapping exactly the first two. If I trace over the same lines, Revit is going to complain that the boundaries are overlapping. :( Seems like a good topic for the wish list.

The only trick I've seen for this, though, is to do the second set of flights 1 inch off the first two. The stairs will not be perfect, since there will be a 1 inch gap between sets of flights. The gaps could be fixed doing some additional work and some line work touch up, though. That's the type of stair I'm showing in the illustration provided.

That's what I thought. I know railings and stairs are difficult and wish Revit could handle them better. Particularly in multi story buildings - you'd think it was worked put better as this is not a random or unique situation. This is how they really exist in this situation. Thanks for your help.

Usually what I do is go ahead and let Revit create the multistory stair for you with the simple railings as you first showed. Then, if you are creative, you can edit the end sketches of the railing to be the shape you want over the second floor slab, but just don't connect them. Then you can add a little peice of railing in there as needed to fill the gap. Not perfect, but it works. At least at that point, your stairs are accurate, and you just have a little bit of work using the linework tool to hid the lines that now show in plan since you have two different railings instead of one continuous railing.

I have found, when you think about it, it's really difficult to get the railing perfect anyway in a multistory stair. I usually end up doing heavy modification to the railing to get all of the code railing extensions and everything else to look right in Section and plan.

For free standing stairs I will usually create the U runs and then use a "Metal Pan" floor type at the landings. Then I group them all together.

This process worked well for us also on a recent project. To add to this, we used a floor slab edge sweep around the landing which mimicked the stair stringer.
