Altering tread and riser hight in ArchiCAD 21

[Anonymous]

I'm pretty new to ArchiCAD and I'm struggeling with the stair tool. I'd like to be more flexible with my tread and riser hight as I'm drawing an existing building that does not have standard measurements. The stair tool seems to have fixed measurements when it comes to tread and rise and I'm wondering if I can alter this?

If your stairs do not have a consistent riser height, you will not be able to model them using the stair tool as I do not believe it allows it.

If it is the tread depth that is changing, you can go into edit mode and modify each tread individually to match what is required. Doing so will make the modified treads independent of modifications to the tread on the main stair settings.

If the issue is that the tool is not allowing you to set the correct riser / tread, then it may be due to the rules of which you can toggle off. Rules & Standards is the first collapsible tab on the first pages of the stair options.

Yes you can actually.
Select the stair in 3D and go into 'EDIT' mode.
Select the tread and you will see the reference plane for the tread.
Drag that plane and in the pet palette using the stretch height option.
This works if you have a tread finish or not.

Oh? I do not recall being able to do this in 21, or it might only be available in 3d. Anyway, no rules with edit mode then.
