Solibri Location questions about IfcSite, IfcBuilding and IfcBuildingStorey

Xavier

Hi all,

We are trying to create consistence rules about Site/Building/Storeys for a public administration, and we have some light questions about Solibri parameters VS IFC parameters, because Solibri do some conversion/re-interpretation, and we would like some clarification.

I attached an IFC and 3 images , with the questions bout Pset Location.

Q1 - Question about image 01_IfcSite:
IFC has information about “Elevation” and “Global Bottom Elevation” , but Solibri seems that only shows one of them. It’s the interpretation of the image 01?

Q2 - Question about image 02_IfcBuilding:
Has the image the correct interpretation of the conversion from IFC to Solibri?

Q3 - Question about image 03_IfcBuildingStorey:
Has the image the correct interpretation of the conversion from IFC to Solibri?

Thanks and best regards,
Xavier Coll

@xavier I´ve had some troubles with this recentley and from what i understand global elevation i Solibri is not set from the Site value. I noticed this when coordination of files had diffrent Site values but still was in the correct Z height when combined. This wasn´t the case in another Softaware witch sets its Z heights from the Site value. I could Be wrong here but it´dosent seem to be so.

So this topic is quite intersting.

If files are exported from revit with real coordinates with PBP set at the project zero, i get these values.

It would be great to know from where the information is taken or even a hint what setup is prefered.
