Hi,
Does anyone know how to joini multiple lines into one single curve/polyline?
In my case I used bimoprh nodes to extract curves from a CAD link. Then I tried to use the node PolyCurve.ByjoinedCurves. This doesnt seem to work 
Create model curves to false
If you even create a polycurve in Dynamo and try to create from it a model curve in Revit, it will again explode geometry and create many lines. You might try to create spline from points of those lines…
yeah you can try
