Hi there,
I want to rotate some diffuser family instances in Revit. I am able to rotate it using the OOTB FamilyInstance.SetRotation node, but it does not allow me to specify the rotation axis.
The Rotate Family node from archilab displays the below warning.
Also, is there a way to rotate system families (Duct, Pipes) etc?

Hello
IN[0] and IN[1] must be list type. Insert 2 nodes List.Create before the Python Node (one for IN[0] and one for IN[1])
Both inputs 1 and 2 are list type. Same warning.
Angles too. You forgot it, I guess.
Now facing this warning.
Traceback (most recent call last):
File "<string>", line 54, in <module>
TypeError: expected Line, got XYZ

elements = []

Did you use rot_axis = line_axis.ToRevitType() ?
In your code I see you try to convert a string to Revit type.
Where do I need to use this?
I’m just trying to rotate a family about a specified axis.
For your case you can use FamilyInstance.SetRotation. It will rotate around Z.
Actually I wanted to rotate about a different axis, x or y, or maybe around a vector?

You should select model elements and as axis a line.
and don’t forget to change radian to angle.
Thanks, but is this how I supposed to use it?
Element.Geometry of DetailCurve and then try it and there is a node for converting Degrees to Radian try it 
Without List.Create of angle. I did not loop over it.

It is all about looping
Please remove List.Create of Math.Degrees.TorRadians
Tried. But it’s not working.
hello
an example with Model Line Selection as axis

app = uiapp.Application
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
toDoList = lambda x : x if hasattr(x, '__iter__') else [x]
elems = toDoList(UnwrapElement(IN[0]))
angleRad = IN[1]
lineProtoTypAxis = IN[2]
outElement = []
TransactionManager.Instance.EnsureInTransaction(doc)
for elem in elems:
line = Line.CreateUnbound(lineProtoTypAxis.StartPoint.ToXyz(), lineProtoTypAxis.EndPoint.ToXyz())
ElementTransformUtils.RotateElement(doc, elem.Id, line, angleRad)
outElement.append(elem)
TransactionManager.Instance.TransactionTaskDone()
OUT = outElement
the base of axis is on FamilyInstance?
