Interesting Geometry and Plane intersect bug

Hi.
I intersected the geometries of the rooms with level planes, but obviously the intersections are in different places. I think there is a bug here. Is there any way to solve this?
I am using Revit 2024 and here it’s my Revit model link:



Level plane Intersect with room geometries.dyn (21.4 KB)

It seems you have different height for ProjectBasePoint and Origin. You can use Level.ProjectElevation to get correct height.

Yes, you are right. It gives this result because the internal origin is higher than 0. Thank you for the answer this is working!
