First, I have been using Revit Architecture for almost a year now and I LOVE it! It is such a powerful program. I say all this upfront because even though I now feel rather comfortable in using the program I am still trying to learn something new everyday. Well today is no exception - I have read almost 30-40 threads today and I cannot find the solution the problem that I am encountering. I am working on a project where I have multiple floors (4) four to be exact. The beauty of what we have designed is that the stair runs are straight with an intermediate landing in the middle of the run. However, at each floor level we have an opening adjacent to the stair to create a four story atrium (See Section.pdf) attached. What we want to do is run a steel tube around the opening that is the same depth as the left and right stringer. This steel tube will be what the stringers will attach to. In addition to all of that I need for the handrail to follow the stair run and wrap this same opening. I have drawn a plan view of what I am trying to accomplish in the attachment (Section.pdf) I have also attached a pdf file called Detail "A".pdf that illustrates what I am trying to get the right and left stringer to do. Also, it shows the section of the floor and steel tube connection. Sorry for being so "wordy", but I am trying to explain in detail what I am hoping can be done in the program. BTW - I am using Revit 2010 - Thanks!

Ok there may be another way to do this but, what I gathered is this Steel tube looks to be a inch or two above the finish floor, correct?? Well i would set your stringer to "match level", then use a steel tube to go around the slab of the floor, the only problem I see is that your stringer will stop at the floor slab, not the top of the steel tube, so you may have to model that part in.

Allen, that makes sense. Sometimes something that is so obvious is so oblivious because it is staring you right in the face. Following up with your suggestion modeling the clipped stringer to blend with the steel tube going around the perimeter of the atrium opening seems to work, but I wonder will it present a problem. If you do the suggestion we are discussing how will the program know how to sweep the stair and then atrium handrail. Does this mean that you model them seperately and then just like the stringer/tube connection you model the gap to make a "seamless" connection. What do you think about this? I will try it in the morning and let you know how it works. Thanks for your response.

Another suggestion that you might try is to omit the stringers from the stair and include them as a rail in you railings. In that way you could have more control over the position that the diagonal steel tube meets the horizontal tube.

I never thought about that but i do like times idea. you could make the steel tube profile and add it as a rail at the bottom. That way when you turned it back on the floor slab it would clean up. Only thing with this that might give you a problem is i know rails like to make funny "jogs" when transfering from the stair to the floor. But you can play with both ideas and see how it works.
