Curved Stair Wall Trim

There's one issue I'm having while trimming the Curved Wall which is under the Curved Stair. Here it is before trimming:

Then I use Solid Element Operations and then I am subtracting with Upward Extrusion. But here comes the issue; The segments of the wall still remain untrimmed I think because of the curve resolution:

Is there any easy solution for that? They (the Stair and the Wall) have the same exact radius. I don't want to increase the radius of the wall.

 

Thanks in advance!

Easy solution?

It is fairly easy.

 

The problem is the wall reference line and the stair baseline do not match.

Select them both in 3D and look perpendicular to the tread of the stair.

You can see the wall is segmented but the stair is actually curved.

So the trick is to use small wall segments to match the stir treads.

But that is still not quite enough, because the wall is still straight.

Place one wall segment at the first tread.

Select both the stair and the wall in plan so you can see both reference lines.

Curve the wall to match the stair.

Now select the wall and multiply with a rotation from the stair centre point, around for each tread.

The wall curves will now match the stair and they will SEO successfully.
