Stair's stringers

hi

 

did you know if it is possible to extend the stringer of a prefab stair, other than with the 3 basic options? I did not succeed in reproducing the Extension of the stringer at the bottom of the Staircase. I have already tried to shift the profile of the steps, but it causes other issue at the landing.

What type of extension are you trying to achieve?

The one pointed by the red arrow in picture. I want the same extension with a offset.

The actual extension is aligned to the stair nosing.

I don't think that can be done. You'll have to model something on the end separately, or model the stringer as a separate element.

Another example for how Revit is sometimes poorly made for standard's details and fine tuning.

let's see what other member can come up with.

Sure, why not?  

Set the stringers lower end cut to horizontal and join them with a solid mass.

Yeah... it's a workaround. But that mean a lot of masses in the project just to cut every stairs.

I hope for more flexibility.

Then modify the tread profile to be set back from the front nosing ref plane.

I've tried this, but it cause unwanted shift on the stair's landing.

You can model the stringer as a railing with the profile in the Rail Structure (non-continuous).  At least in that case you can control the sketch.  It comes with its own issues, but could be a workaround until Autodesk decides to add some flexibility to the stringers.

The problem is with Revit.  The program did at one time have the ability to modify the stringer extensions.  I think the last version that had this feature was 2018.. Possibly 2019.
