Hi everyone.
I'm using Split Building into Floors (CreateFloors) tools from 3D Basemaps toolbox. However, I've been receiving this error frequently. Can anyone explain why I received the error and how to solve it?

Attached together is the image of how I configure the input

I actually want to separate my building 3d model by floors just as the link attached.

I also welcome you all to suggest alternative ways to separate the buildings 3d model by floors besides using this tool.
