    Sloping Curved Wall With Top Cap

    Alright, I have a circular set of stairs with a stone wall for the "railing". The wall curves with the stairs, as well as sloping parallel to the stair treads. Easy enough. I created a face based sweep blend to create this condition properly. So far, so good.

    Now, I need to apply a cast stone cap. I tried using a fascia with a profile along a model line, but that won't work. The model line stays flat along the level, it doesn't follow the slope of the curved wall. Therefore, the fascia is just a flat semi circle cutting the wall. No bueno.

    I guess I could model the exact wall cap as a face based family and just set it on top of the wall, but then I would have to get the curve and elevation change exact. It sounds like a lot of work.

    I did this a few years ago with an in place sweep blend, but for some reason I can't get the path to stay on the sloped part.

    Is there an easier way to accomplish this??

    Bonus question:

    Look at the sliding door going into the observation tower. The wall is a vertical wall with a slanted stone wall in front of it. How would you suggest filling in the gap at openings?

    For the curved/sloping wall and cap--you could use Conceptual Massing.

    Another possibility for the sloped cap would be a custom "railing" with a profile for the cap, with vertical and horizontal offsets--ala Phil Read's crazy stairs methodology.

    I'd probably just do walls with a profile edit for the triangular infill areas, since it appears there are only a couple of them.

    ahhh never thought of a railing. That might just work. And massing as well. I never think to use massing. I'll have to look into that.

    As for the infills, I think you're right. I was just hoping there was something easier than creating walls. But, it shouldn't be that bad.

    The designer told me just don't worry about either of the issues, but it's bugging me. I have to fix it.
