Bottom ede of balusters is not cutting in line with stringer

[Ross_Robertson]

Hi,

I'm putting a domestic stair together and can't seem to get the bottom of the balusters to cut to the line of the stringer. Any assistane with this would be greatly appreaciated

Edit the baluster family and make sure you have a void constrained to the angled reference planes.  Also, uncheck 'Post' parameter.

Hi ToanD,

Thanks for that, I've edited the baluster and constrained a void to the sloping reference plane and reloaded but unfortunately its still not cutting, strangely the top void is cutting and is set up in exactly the same way...

Can you change host of the railing to Stringer instead of Run?

Hi,

Sorry for the slow reply project work took me away from revit. 

I don't know how to set the host of the railing to stringer instead of run, do you? Any help greatly appreciated

@Ross_Robertson, can you upload your stair? It’s much easier to troubleshoot having the actual file, rather than guessing the issue.

Hi,

I've uploaded two files, the 2017-25 one is the one where I had the original issue, as a workaround I set a lower rail as a capping to the stringer, it works but the height of the bottom rail needs adjustment for each pitch which is not ideal.

The 2017-37 file is another file with similar features, this has a half turn winder stair, Revit just cant do the stringer/handrail as its built and the winder stair tool won't allow the stair support/railing to be created with this geometry. The stair exists, (photo of actual stair also attached), and is compliant with current regs so I think the software should be able to model this condition given its cost.

I guess my questions are:

How do you get the balusters to cut at the stringer/support without the bottom rail workaround

How do you get the stringer/rail to work at a winder stair with tight geometry

How do you set the lateral offset of the stringer, the control is greyed out. in this case I altered the sketch

[ToanDN]

See attached file and screencast.  I am getting tired so I will look at the other file another time.

Thanks Toan, that solves the baluster issue, any help on the winder support/railing issue would also be great.

@Ross_Robertson

Adding the railing to the winding stairs the way it shows in your photo is really difficult.  The slope of the stringer in the photo is not the same as the slope of the stringer generated in Revit.

If you insist on building the railing with Railing tool, you would need to create a piece of sloped floor to fake the stringer then host the railing on it.  You would need a special posts at each ends so that the stringers meet the posts at the square portion like in the photo.  Attached screenshot is what I did with the above approach.   I didn't get to creating custom posts since it would be quite time consuming.

It maybe easier (relatively) just modeling it as an in-place piece.

@ToanDN Many thanks for your assistance, I was able to model this in place, hopefully future releases will allow this to be modelled using the stair tool. One thing I noticed while modelling the stringer was that the railing support subcategory had no phase parameter...

Hi,

I've been trying to do something similar, to get balusters to trim to a stringer, but it seems that once the stringer sits below the bottom edge of the treads, the balusters won't go down to it - see image attached.

Any suggestions about how to fix that?

Thank you!
