Building explorer for underground floor in ArcGIS Scene Viewer

[MCh]

Hello everyone,
I've got a problem with the building level when upload .slpk to use building explorer in ArcGIS Scene Viewer.

Which field of BIM data structure in ArcGIS Pro 'actually' represent to this floor level in the building explorer widget?

How should I do to get the underground level or rearrange the level for the widget?

Thank you in advance!

Hello @MCh 

What you are expecting and describing is data organize for O&M usage, but what you are showing on the screen capture is design and construction data which is completely  different.

You will need to  modified your BldgLevel domain  and maybe some of the data to fit your needs .

If you want to talk message me directly.

I don't quite understand what you mean by the difference, but your answer has helped.
I can't find the right field because the existing domain is messy, they use 1 for B1 and 2 for 1...

Thank you!
