How to place wall on spiral ramp

[VaclavC]

Hello,

  I need to create 1m tall wall on edge of spiral ramp. Ramp is created as floor element with vertivally modified subelements. I can attach wall's bottom to the ramp without problem. But how I can attach its top at height of 1m above the ramp?

Hi,  I had this issue,, and found the work around with drawing the wall as a ramp and increasing the thickness of the ramp to 1mtr,,

hop it helps

kevin,

Hi Kevin, thank you. This works and I can use it. But it seems a bit ugly to me. One problem is, that I cannot join the ramp with anything and, as result, I'am missing intersection lines with other elements in elevations and sections. And there is thick line between ramp (Revit floor) and railing (Revit ramp) in section. Which can change manually, of course, but it is ... ugly and inconvenient.

Yes I agree with you,, but it is only a work around to get the elements to fit,, try overriding graphics by element to clean them up a bit

[VaclavC]

I know about graphics overrides and as a workaround, it works.

I can also do it as Model-in-place, tried it right now. A bit better, but no ideal solution as well ... I can join it with some other walls and get missing intersection lines in elevations. But when I try to join it with ramp (Revit floor), I'am getting error "Can't cut joined element".

Wanna to have some nice "Revit" way, how to do this ;-).

Ramps don't join with anything. That is just one of their many limitations. I have proposed to eliminate the ramp tool from the program.

[VaclavC]

I guess, that they were useful when Revit was unable to do non-flat floors. Don't know Revit history, however, I started with version 2016 last year...

Finally I made it as floor. I was unable to create a sweep with strict vertical profile, it rotated mu rectangular profile to be perpendicular to a helix path (edge of ramp). And I'am getting errors if I try to make it exactly one meter high and join with ramp floor. It must have some cross section. The floor I'am able to join with anything necessary.

I would create a spiral conceptual mass and assign wall by face.

[VaclavC]

Tried it, as you suggested, but it seems to me as far more time consuming than create it with floor. I can copy ramp floor, change its type and edit profile by offsetting inner arc of ramp (I need railing on outside arc). Manually entered heights remains, if I do it this way.

But, when I create it as you suggested, Revit has no problem with helix shape of wall. It would be nice to have something similar to "Modify Sub Element" tool accessible when modifying floors. Then I can create such a wall directly, without working with conceptual masses.

Hi,

I attach a sample file being 4.4MB in size, in which railing is used to form wall on ramp.

I hope it works.

[VaclavC]

Thank you. But railing has similar problem like the ramp - I cannot join it with nearly walls.

Create a spiral conceptual mass is rather easy to be honest.  The one below I created with a rectangle profile sweeping along a semi-circle, which is unnecessary.  You only need to sweep a vertical line to form face so you would need fewer steps.

No matter how you do the wall on top of the ramp, it won't join with other typical walls. 

Another way to do it, to avoid the twisting of the profiles at the ends, is as a model in-place with a flat arc as the path (picked from the top view of the ramp), and two identical profiles, one at each end of the arc. Then, use the Vertical Offset parameter of one of the profiles, to make the sweep adjust to the height of the ramp, as shown below.

Great, thank you all. You gave me several solutions, now I don't know, which one should I accept as solution ;-).

No problem. A thread may have more than one solution.
