Curved Stairs problems

[guillermo4JEUL]

Hi everyone, I'm having a hard time trying to finish this stair that you can see in the pic. So the difficult thing here is that I need to close the stair underneath with gypsum and put lights there, and also need to fix those railings. The stair boundary is made with different arches because the original plan is oval, and Revit does not let us do ellipses in stairs, and I think that is why the railings are having those small flat pieces that is another thing I want to fix. 

So my question is, what would be the best practice to finish this stair? 

Thanks in advance!

You can create the ceiling from a Mass and Wall by Face (see screencast).  As for the railing, please share the file.  If all else fail, you may need to resort to model in place.

How did you create the stair? Component or sketch?

ToadDN: Thank you for the explanation!, I'll try to do that, I'll let you know if I got it. 

Rina: For this project I'm using Revit 2018 and there is only one type of stair now, so inside the stair tool I use the create sketch option, because of the complexity of the stair, that was supposed to be an ellipse originally, but as is already know we can't use ellipses for stairs, so it is a succession of arches .

When I need to create an ellipse stair and/or railing, I sketch the ellipse in AutoCAD with Pellipse variable set to 1 so that the ellipse is actually a polyline. Then I import or link the polyline and use it to sketch the stair/railing with pick lines tool.

Thanks for the tips, I manage to do it with the technique of the mass. It was a little trickier though, but I made it. Thanks!
