looks like unit is based on current Revit project setting, anyone knows how to specify it like below:
Autodesk.Point.Add(Autodesk.BoundingBox.MaxPoint(bbs), Autodesk.Vector.ByCoordinates(3000mm,3000mm,3000mm));
edit: fixed by adding PythonScript node to convert
Convert to project units - Dynamo (dynamobim.com)
Dynamo geometry is unitless; you are reading in stuff from the project into the unitless geometry of Dynamo. So to use a specific unit type you first need to get the project’s unit type, and then convert from your given units to the project units.
There are nodes to help do some of this for you in modern builds (2.12? 2.13? I forget which):
