Hi everyone,

I would like to convert a “model line” into a “reference line” inside Revit.  
Is there a way to do it trough a dynamo script, otherwise accessing the Revit API?  
Does anyone know some method to solve this issue?

Thank you

Here’s the API method: [ConvertModelToDetailCurves Method](https://www.revitapidocs.com/2020/5566ffcf-1724-589b-15a1-6e829a986ec2.htm)

If you want to skip python you’ll likely have to get the curve geometry from the ModelCurve and use that to create a DetailCurve. Then you can just delete the old ModelCurve.
