I am trying to use dynamo to convert lines from Acad into Revit Reference Planes. Right now I have imported the Acad and trying to use them to create reference planes. I dont know where to go from here. Please see what I have below. ---

Hi @a.corriveau have a look at this node here: [http://dictionary.dynamobim.com/#/Revit/Elements/CurveElement/Query/Curve](http://dictionary.dynamobim.com/#/Revit/Elements/CurveElement/Query/Curve) The CurveElement.Curve node will produce the curves from your ModelCurve elements, which you can then use to obtain their start and end points 🙂
