Winder stair drag

How do I move that slanted green line to the blue line I’ve drawn there? I’ve pressed loads of buttons and it hasn’t worked; I’m stuck.

Watch the attached images and GIF with the whole process.

Afterward, you can still modify the staircase. Adding some guide lines at the width of the stairs helps.

You cannot go narrower than the staircase itself, which allows you to snap to the minimum width.

Thank you in advance, but I only want the diagonal line to shift so that the distance between the landing and the riser offset remains at those values: after=500, before=250. So the point is that the diagonal line is at the corner, but the riser offset remains at 500 and 250. Thank you.

Hi @horewa,

You can achieve this and set it up as the default, when creating the stair by fixing the "Minimum riser offset" values as connected (or equal) parameters.

Please check the short video below:

Hope this helps 🙂

Cheers!

Is it possible if the offset is not equal but the diagonal line remains at the corner? This is what the line that remains at the corner looks like

turning off all rules and standards will also help open up some configuration options that may be getting locked out or impossible to apply

Hi ,

As far as I know this feature is still missing from the Stair tool... at least for the Structure part of it...

For a bit on this you can check out this thread as well: https://community.graphisoft.com/t5/Modeling/Stair-Winders/td-p/286085

What you can do is a "bit" of a workaround... But hey if you want to have unique geometry, you have to think outside of the box

So here is how I would approach this exact issue:

Option 1

Turn off the structure part of the stair and only use the Finish.
With the Finishes use the Tread only option.
Set the thickness to something big and the material to your liking. (We will cut off the excess, but more on this a bit later.)
Draw your stair.
Modify the corner by overriding the Turning Type Options at the corner node. -> Now it is still won't look good, but...
You can actually edit the geometry of the threads. SO go into the Edit mode and modify the thread geometry to your desired shape.
Then you can create some operator elements to define the underside of the stair and use the Solid Elements Operations to fix that part as well.

Pros:

It stays a single "Stair" -> You still have the numbering, walking line, etc...

Cons:

If you edit the stair in any way, it will be messed up again and you need re-adjust the "Edit" all over again.
The SEOs can burden your model if you have too much...
In case of geometry editing, you have to keep in mind all editing elements and the maintenance can be a plus burden.
If you wish to have actual threads or covering on top of the stair you have to model that separately.

Option 2

OR you only model the thread geometry with the desired thickness and materials that you would love to see as the covering on top of it.

And you model the structure as a separate entity under it.

This short video will show this workflow, but Option 1 can be achieved through the very same workflow you just play around with the operator(s) a bit differently.

Option 3:

You can also model it by using 2 separate Stair elements for the straight runs and then model the winder from separate slabs...

Hope this can help in some way, and I really hope that GS will be able to update the Stair tool so the structural part of it can handle such "complex" geometry as well.
Or they can show us a workflow how to achieve this... For I am dumbfounded that such an easy looking geometry cannot be achieved with more ease... But I really hope that someone more knowledgeable can provide eventually a better workflow. 😕

Cheers! 🙂
