How would you go about this?

I am making a model stair case and I cannot figure out how to make a plane (or is there another tool that will do the job) that will allow me to make walls/ railings that will follow the path of the staircase.  Is there anyone that would be able to help me with this issue?  Thanks!Screenshot 2024-06-03 144150.png

This is what I have got so far, but if you look at the second picture, you will see that it does not line up with the staircase.  I was able to make the railings, but that did not work, and I don't even know how to do the math for this one.  I know that there are stair calculators but I have looked and none of them will simulate ANYTHING like this.  I also work for a custom stair manufacturing company (Viewrail) as a Project Engineer, so you think that I would know how to do this, but even this one has stumped me!

Looking down from the top.  It should be 2 cylinders at center of steps.

So the path should be 2 helix.  One right hand, one left hand.

That I understand, but I would like it to fit not just the 2D perspective, but the 3D perspective.  I want the railing to follow the rise and run of the stairs perfectly while still having that smooth flow.  Does that make sense?  Same as the picture above, but with no inconsistencies.  I want the bottom edge of the railing to meet at the edge of bottom tread and same for the top to maintain a consistent height handrail.  I know that this is a tough one in general so I am not expecting perfect answers.

The 2D is circle.

The 3D is helix.

The lower steps are on left hand helix.

The upper steps are on right hand helix.

Oh you got a "straight" step in between.

So helix with straight line in between.

Hi!

 

But... you want to have the guards equal in both sides, right?

Can you share your model to see what youre doing wrong?

Well.... Help to understand better the problem, but doesnt help to solve it, since we still can't know how you do it.

All i can say is, the coils will be different from both cases, and it seems that you are using an equal coil for both cases.
Without the files is not possible to give you a real fix.

Without the file(s) to work with, I would say that I would start by creating vertical surfaces defining the walls of the staircase.  I would then create 2D sketches to define the slope of the step noses and wrap those sketches to the wall surfaces to define an array path for the individual steps.  The steps appear to be identical with the exception of the straight step at the transition, so this could be done with two arrays.  Then the rail paths can be copies of the stair paths, copied upward the required amount.

 

The walls would then have upper and lower boundaries defined similar to the steps paths and wrapped to the wall surfaces, then thickened into solid walls.

 

I'd enjoy taking a shot at it if you're able to post the actual file(s), or at least the applicable dimensions.

 

What version of Inventor are you using?

I was actually able to figure everything out.  I used the helix tool in a 3D sketch and then used "Ruled Surface".  From there I used "Thicken/ Offset".  I just did some really basic geometry and trial and error to get everything to work.  I am really grateful for everyone's help and guidance!  Here is a picture of the finished product, and the file.  

 

P.S.  I am using Inventor 2021 for work but we are upgrading to 2024.
