I’m curious to know why this node returns weird resutls?
Is it because of the unit conversion happening in the background?
@Daniel_Hurtubise Could you also show what does in Revit looks like?
If you suspect this then check it out.
@Daniel_Hurtubise Try to create levels through dynamo. It gives you perfect results 
This is using Revit.
Glad to know i’m not going crazy 
Those we’re already created. Rounding to 2 decimals usualy does it though.
