Curved, Spiral, Helical Ramps

[tiagofrbr]

Hi! How can I model a ramp like this, using the ramp command only once ? (I would not wish to use slabs or more than one instance because I want a continuous helical geometry). Let's assume the slope is the same for all the ramp length. When I try to complete the ramp using this sketch, Revit acuses an error and it doesn't allow me to do it. I am using Revit 2025.

I made some tests and it seems it works fine as long as the two side wings are equal...

But , if the wings are unequal ( even slightly ) , Revit report an error (as you experienced too)...

It has to be a glitch of the program

Exactly! I made the same tests as you did and got the same results. Unfortunatelly couldn't find a solution or a workaround for this...

I'd rather prefer to make the Ramp automatically by Run .... as you can see in my screencast:

Thats an interesting aproach. You can also do the same thing creating the ramp by sketch, you just need to have two risers lines overlapping at the start and at the end of each curve. The result will be the same as showed by you in your video. However, it looks like the straight parts of the ramp loses their helical geometry and becomes a simple angled ramp. I don't know if that's supposed to happen but it doesn't seem to be correct, although this may be the only way to do it using this "Ramp" feature in Revit.
