U-Stairs - 8.1 can't make

[sbrown]

I have made this stair dozens of times in previous releases, In 8.1 I can't make it without a tiny straight segment at the top of each run, could someone please verify that they too can't make the following stair. I get an error about the Stairs require no more than two boundaries (chains of one or more Boundary Lines).

Thanks.

I had another user here in the office run into an almost identical stair situation yesterday with a stair created by run. I couldn't find any problems with the automatically created boundary, but when I selected everything, filtered out and deleted the boundary lines, and then redrew them in exactly the same place it worked. I'd say it's a bug.

I tried that and got the same error, so I decided I'd leave a little piece at each landing and it worked, the railing was fine, now I needed to edit the sketch to get the image in the attached jpg and the railings flip to the outside, then drop of the face of the earth when I edit them to pick host. Any ideas?

I still work in version 8.0 and I have exactly the same problem. I have simply resigned to leaving 1mm boundary line at the "turn of the landing".

With so many other, more important things in REVIT not working to my expectations, I simply assumed that this tool is just (somewhat poorly) designed like that...
I didn't have many similar situations, while working with previous versions, so I thought that it has been just like that from the begining.

The problem has always been there. The trick is to Sketch the stair away from all intersecting points, (or bigger than it really is.Stair 1.jpg). Then move the runs back to where they should intersect, delete "lines to short" and left over boundary lines(often found lying over treads, depending on how you moved the runs), Finish Sketch.

ZEDS that is how I used to accomplish the goal, its not working for me now. I always sketch my stair big with much larger landings then I bring them back in and delete extra line segments, always worked in the past. Now its not.

Scott there must be a boundary line over or under another. The otherway is to set out accurate ref planes for the center line of the stair. It just takes longer than the other way but does work.

Not the exact same stair, but similar. Created this one in 8.1 without any troubles. I did have one with winders that was giving me trouble and the problem was I didn't have the boundary lines split at the landings. Same error as you are getting.

Looks like you got it, Maybe it has to do with one of the stringer settings in my stair or something. I know the boundary is closed because I've deleted all boundary lines and re drew them endpoint to endpoint.

Anyway, thanks for all the help.

Did you split them between the landing and riser at the landing?

[sbrown]

Yes. each run has a line segment and each edge of the boundary has one. basically you need a break wherever there is a change between flat and sloped.

Hope you didn't take that the wrong way, I know you have been using Revit for a long time. I was having a similar problem today on a stair, but it was a doubly curved custom stair that wrapped around some column bases. I basically had to redraw some boundaries and risers to make it work. It highlighted which one was giving the problem, I would redraw, then another would pop up somewhere else. I just kept redrawing until it worked and making sure I was snapping to the stair lines for snapping purposes.
