Is there any way to create a leader from a Textnote to various points using Dynamo or a Python script with the endpoint specified by coordinate(points)?

YES! THANKS! But I can’t find those nodes in my library. Can you share with me how it’s done?

Hi,

This is I would do it:

  1. Search the method in the revit api docs:
    AddLeader Method
  2. Find information about the “Leader”:
    Elbow Property
    End Property
  3. Look for some examples in the revit api forum:
    Solved: CREATE LEADER - Autodesk Community
  4. Convert the code into python:
import clr
# Import RevitAPI
clr.AddReference("RevitAPI")
from Autodesk.Revit.DB import *

# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
app = uiapp.Application

textNote = UnwrapElement(IN[0])

TransactionManager.Instance.EnsureInTransaction(doc)

for i in range(1,5):
    leader = textNote.AddLeader(TextNoteLeaderTypes.TNLT_STRAIGHT_R)
    leader.Elbow = XYZ(15, -0.75, 0)
    leader.End = XYZ(15, 5+i*2, 0)

TransactionManager.Instance.TransactionTaskDone()

OUT = "Done"

Thank you all very much. This has really helped me a lot.

P.S.
I’m a beginner and I want to learn how to use APIs from the basics. Do you have any recommended learning resources? Thank you in advance.
