Hello,

Can I use this script to convert Modellines into RoomSeparationLines or AreaSeparationLines?  
On Revit Docs I find something, but it is absultly cryptical to use

Tricky stuff 🙂

```
import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
import Autodesk

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

ModelLines=UnwrapElement(IN[0])

CurveArray = CurveArray()
[CurveArray.Append(i.GeometryCurve) for i in ModelLines]

TransactionManager.Instance.EnsureInTransaction(doc)
Autodesk.Revit.Creation.Document 
docCreation = doc.Create
sepLines = docCreation.NewRoomBoundaryLines(doc.ActiveView.SketchPlane, CurveArray, doc.ActiveView)
OUT = []
for i in sepLines:
	OUT.append(i)

TransactionManager.Instance.TransactionTaskDone()
```

What is the comment for AreaSeperatorLine, Can i do it also… i tried just to replace Room by Area, but it isn`t so easy.

Thats realy a step forward. Because my final wish is to convert dynamo curves into ! I will post it soon[convert\_dynamo\_curve\_into\_RoomSeparetor.dyn](https://forum.dynamobim.com/uploads/short-url/cu6EagpL1i0vV3Vb5xiCFrKoH47.dyn) (39.1 KB)

Convert or create new? Clockwork has nodes (and python) for creating.

The workflow is following:

I have a contur of a building, it is a polyline. I link this .dwg - each floor in Revit, level by level.  
I would like to “convert” these lines (linked lines) to a “RoomSeperationLine”

The collection works very well!

Need I a “retrace-workflow”? How would it be?
