Why is the stair wrong?

agroni

Hi,
can anyone help me and explain why the stair does not fulfill the size of the landing?
The ruleset is set to 900mm and the landing is much bigger than that…

I actually get for all the stairs the same problem!
Any clues?

Often (normally?) the landings are ifcSlab. Maybe the rule checks only ifcSlab within a ifcStair and your landing does have a different entity or the stair is not an assembly.
Just an initial guess

agroni

thanks @hkringsKUBUS bus sadly was not the case.
You are correct that the middle landing is an IfcSlab Type LANDING, which is also in my case:

Even solibri detects this part of the object as a landing, because in the error message (first post) he mentions the “Zwischenpodest” (ger. stair landing). It does not matter if the geometry of the landing is just rectangular or not, he cannot find the correct dimensions of it, hence resulting in an error.

Does anyone else experience the same problem?
@Solibrians are we dealing here with a bug?

agroni

anyone?
any feedback on this case?
any experience with this rule?

agroni

@Solibrians
any chance on getting some feedback about this case? On my tasks it is still open and getting tons of false reports from Solibri.
Or does the silence mean that I should maybe just turn off this option an simply ignore it?

@agroni How do you modeled the stairs in your software (Archicad )? Ist this one element? Did you check to seperate the stair in three parts?

agroni

@chris
Yes, it is in Archicad and it is modeled as one piece.
Yes, we also have a project where stairs are composed out of two stair flights and one landing in between modeled separately. In this situation, there is no error.

I would like to know if Solibri is checking the IfcSlab TYPE LANDING with this rule, or how is it establishing that the landing size is not fulfilled. Based on what parameters or geometry. In our case, we will almost never have a mid-stair landing that is modeled separately, especially in the early design phases. It is simply not efficient to work with three elements instead of one. Therefore, it would be really helpful if Solibri could check the mid-landing not matter how it is modelled. In my opinion the key aspect for checking should be IfcSlab TYPE LANDING.

@agroni Maybe it is how the Ifc Geometry is exported from Archicad… I had similar issues with Elements from Archicad (Stair, Beams, Facade…)

But yeah, @Solibrians, any suggestions on that?
