Handrail visibility issue

[Keith_Wilkinson]

I've come across an odd problem on a project with a handrail not displaying as expected - or rather displaying where not expected.  I've set up a clean file and created an OOTB stair and I'm getting the same problem so I'm figuring it's a revit issue rather than something specific to the project such as view ranges etc.

Basically if I create a stair where the first run is longer than the others so that it overlaps with the landing at the first floor the extended portion of the handrail shows at first floor level (see attached image).

Anyone got any ideas what is causing this and if there is a way of preventing it?

Looking at the stair properties, I see that the Base Level is set to Level 0, and the Top Level is set to Level 1. However, the top of the stair is going to just below Level 2.

Additionally, changing the Top Level to Level 3, does not move the stair up past Level 2.

However, if I cut and paste the stair, then it switches to match the parameters listed above, and after changing the Top Level to Level 2 (so that the stair goes through Level 1), the railing is not displayed in the Level 1 plan view. I created the following video showing this:

What steps did you go through to get the stair into this state?

Hi Lance,

Thanks for looking at this.  The link below is to a screencast showing the method I used and also showing the general issue I have with the way your stair was created.  I do however fully accept that the second method is by far the more robust but please take a look and let me know what you think.

I am glad to see that you can create the stair without showing the problematic railing.

Regarding the change in desired number of risers, I believe this relates to calculations that are done after the property changes are applied. (I.e. Revit is estimating that going from Level 0 to Level 1 would require 22 risers, and then changing this value would require 44. However, after applying this change it is finding that it actually only needs 43.)

If you add a Top Value Offset of 110.1 or more (this was the minimum required value in my copy of Test stair2A.rvt) then the value will remain at 44.

Just a quick summary.

The stair in question has a longer initial flight at ground floor level which shows through to the landing above. 

The cause of the problem was creating a multistorey stair but starting with the parameters of having it go only from Level 00 to Level 01 and then adding additional flights and landings manually.

Creating the stair using what Revit would read as 'correct' methodology, ie the stair runs from Level 00 to Level 02 fixes the problem.  The only thing that you need to watch is the size and quantity of risers.

Quirky perhaps but it works if you 'do it right'!  ;o)

thanks to Lance for solving this.
