curved sections

[ihammerhands]

I have a curved staircase that needs a curved section through it. Any suggestions from someone who has delt with this?

Hi Millard,

Unfortunately you can't do curved sections.

You could try making a series of straight sections, based on facetting an arc in plan, then crop and join them on a sheet, but I'd be doubtful about the final result.

I don't recall seeing this mentioned in other topics before.

I would just draft it, use a straight section, to get the hieghts from the model and then just turn off the model and use detail lines and components to make up the section. You can then make a section tag that has not line and just draw the curved section line.

i realize this is an older thread, and i was wondering if anyone has found a better solution. The only one i can come up with is to split segment. doesn't seem like a great idea.

i'd appreciate any better ideas.
thanks in advance,
jamie

Best bet is just linear section.
It would look better anyway while it shows the stair turning rather than straight run.
Just wondering...Why would you want to do a curve section anyhow?

because it's the only way to accurately show the stair in section... all other cuts force the geometry to be the wrong size... like sectioning a sloping floor in plan or an angled wall - all of a sudden what should be a 6" thick element scales to 4 or 5 feet!'

i wouldn't expect Revit to do something like this though... sort of like asking it to understand where to display an angled column line in elevation.

Documenting unique geometry is sometimes best done in an axonometric view. In Revit you can create a 3D view, turn on the section box, isolate some categories, and set the active work plane to your treads and dimension / annotate.

Just thinking...spiral stairs are essentially a continuous condition, so couldn't one just detail a portion - say 3 to 4 steps - and that would take care of the main body of the stair...then detail the top and bottom conditions separately? I realize ideally we like to show the entire stair in section, but an axon as described above for general reference of the stair arrangement and overall dimensions and several section details should be adequate for fabricator shop drawings (if applicable) and construction.

I would think a continuous "curved section" might be overkill.

I Agree with you on this one.
I also think that a curve section would probably be best described with the word Profile. There should be a profile option in revit that would enable Revit users to flatten things up such as a spiral stair, or curved walls for the sake of detailing.
