    Railling on a bridge ?

    I created a curved floor by Extrusion. Then I want the railling going on the slope, like a bridge. How must I do ?

    You can't. Maybe use a curtainwall with Edit Profile for the railing instead...?

    Using curtain wall is OK. But how deal with the type of balusters ? For example, glass panel with brackets ?

    Have you tried starting out with a flat shape & then Modify Sub-Elements? You can add pick points at very small intervals, raising the profile gradually to the mid-point, then back down. As a series of short straight lines - it might accept the railing to follow. I would probably try the railing as incremental segments, too - I cant see a top rail making an arch.

    If I create flat floor then modify Sub-Elements , I can't Pick New Host to that floor !
    Can only Pick new Host in case of using Slope Arrow.

    I just tried my proposed method and, you're right, it doesn't work. So? In a pinch make an in-place model...

    You can create the bridge with a mass famliy and ad a curtian wall by face on it the face of the curve bridge. Apply a 1/2 step pattern to create the railings, which allows the railing profiles to follow the curvature. Railling on a bridge ?-bridge.jpg

    Here is a video and a sample family file of the adaptive component.

    After trying out my earlier suggestion and a few stabs at different iterations, I came to the conclusion that railings are hard-coded to be strictly linear. BUT WAIT! I went back to a current project where we have a circular staircase - and the railing is sooooo nicely and appropriately curved. So - WTF?
    Railings have always been largely frustrating (even with Phil Read's cute tricks) and usually a big wish list item.

    Maybe the Factory chaps are hard at work with some Elves brewing up a brand new Holiday present.
