spiral ramp with transverse slope

[Anonymous]

Hello everyone,
I’m working on a spiral bridge. I don’t have any idea for covering floors.
In my first attempt I’ve tried using floor tool under the structure tab. But it doesn’t work. Because floors need to be drawn on a certain level. Unfortunately, there isn’t any flat slope in my project.
I’ve tried using pick supports option but it doesn’t work well.
In my second attempt I’ve tried using ramp tool on the architecture tab. But it doesn’t work quite well too. Cause my ramp have a transverse slope.
Any one have any idea?

Hey Arash,

Thera are two available modelling strategies you can choose.

1. Create an In-Place Mass model and use the command Floor by Face.
2. Create an In-Place Mass model or use any other building component to create a path for your Sweep within your custom component (Model In-Place)

Find attached a Revit file with these two examples. Which one do you prefer?
