Complex path for railing sweep

[roothcad]

Hi, I'm trying to create a stair guard/railing as a continuous sweep for a few levels. I created a conceptual massing model that describes the top edge of the rail and the bottom edge of the stringer and used these edge to select a 3D path for the sweep.

The problem is that the profile flips out of plane as soon as it gets to the first slope.

Suggestions?

Is what I'm doing even possible to acheive?

See attached

Thanks!

Yes. It is possible. I assume you already tried with the railing tool but it didn't work? Another way to do it is with a sweep, as you are trying. Below is an illustration showing the process of making a door handle that uses a path in different planes. I hope it helps.

Thanks - from your diagram I see I was trying to turn the corner to tightly. Unfortunately, the shape was too much for Revit to handle and kept givng me "cannot create" errors.

I'll make do with what the stairs have to offer

Cheers

It's not that this is too much for Revit. It is possible. Please provide the 3d path and the section profile.

Eye of a stair modeled - sweep crashes with even a simple rectangle profile.

Knock yourself out!

Ooops attachments didn't go through...

Here's the railing, using true stairs and top rails.

Well, I tried to attach a DWFX file to allow orbiting around the 3d view, but the forum does not allow DWFX files as an attachment to the post. (?)

Awesome - thanks so much!

One more question - does the top rail display in plan correctly?

[Alfredo_Medina]

No, there is a discrepancy of 19/32" between the display of the top rails in plan, and their actual location in plan (which is visible if you hover the mouse over the top rail). It is very strange and I don't have an explanation or solution for that. 

I have attached the Revit model.

How can you make this glass railing family work with a curved stair with intermediate landing? I have the issue of the glass profile not following the stair cleanly and at the bottom of the stair, the glass rail is not cut plumb with the baluster.?

Thank you
