Hello,
I am using Revit 2023.1
I attached file + scriptFichier Test.rvt (2.4 MB)test_to_see.dyn (23.0 KB)
Code Python
import clr
import sys
import math
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")
import Autodesk
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *
doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
app = uiapp.Application
uidoc = uiapp.ActiveUIDocument
#######OK NOW YOU CAN CODE########
elt=UnwrapElement(IN[0])
ang=IN[1]
def r_cent_l(i,a):
loc=i.Location.Point
Line_axis=Line.CreateBound(loc,XYZ(loc.X,loc.Y,1))
TransactionManager.Instance.EnsureInTransaction(doc)
ElementTransformUtils.RotateElement(doc,i.Id,Line_axis,math.pi*a/180)
TransactionManager.Instance.TransactionTaskDone()
z=[r_cent_l(e,ang) for e in elt]
OUT = z
I thank you in advance
What is the location point of the family in question?

THANKS,
this is the 1st element of the series which is placed in a disorderly manner
if the elements are already in place I have no problem
Where is the drawing’s internal origin and X/Y axis? (Relative to the wall which is placing our of position)
Hoping not to go off topic in the answer
cordially
I have to add a transaction end before the Python node
to avoid this inconvenience (from the 1st object placed in a “strange” way)
but I get multiple routines launched in this case (weird)
I’m taking up a little too much of your time, thank you for trying to solve it.

Draw Dynamo point at the origin and display it in the Revit preview. My thought is that the family is rotating about the origin as this is kind of in one transaction…
I tried to implement your idea
THANKS
Try this
doc.Regenerate()
z=[r_cent_l(e,ang) for e in elt]
OUT = z
Had a similar problem not a long time ago.
So I think this is just how transforms work, you have to do a rotation and translation.
Trying to put this all in one python node gave me the same problems, I had to run the code twice with commented out rotation/transaltion to make it work, but now i found the root of all evil:
The key to success is doc.Regenerate()

Also works this way:
TransactionManager.Instance.ForceCloseTransaction()
z=[r_cent_l(e,ang) for e in elt]
OUT = z
I´m often having troubles with placing and rotating though, I sometimes have to place, rotate, translate back to make it work…

Hi, This method no, but I will keep the doc.Regenerate()
sincerely
Hey @christian.stan ,
both methods work, because of this:
Note that when a transaction is committed there is an automatic call to regenerate the document.
Online Documentation for Autodesk's Revit API: 2015, 2016, 2017, 2017.1, 2018
So somehow the transaction from placing the families is still open and , as you also showed with nodes, you just have to close it.

I did some trials - the first placed instance of the family appears to have the Location set to 0, 0, 0 while inside the transaction when using the dynamo Family Instance node or with doc.Create.NewFamilyInstance() in python
If you use the Dynamo points as the location for the rotation axis it works ¯\_(ツ)_/¯
And discovered the Element.Location.Rotate(axis, radians) method exists
