Whats wrong here…I tried to find an example for this node but i couldn’t…! ![1](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/f/8f6c976f88ff01839673d18c5fb97209ed5aa479.JPG) ---

Try with a plane instead of reference plane maybe… ---

The outline input is maybe not correct, it should probably be the footprint perimeter lines of the roof… ---

I have tried all the options…here is the dyn file you can try it [test roof node.dyn](https://forum.dynamobim.com/uploads/short-url/sywQVp3No25D03L5mYxFb0dUtq5.dyn) (14.2 KB) ---

Have you tried this node before ? do you have an example you have done before? ---

Not yet, the illustration is still missing in the [Dictionary](http://dictionary.dynamobim.com/#/Revit/Elements/Roof/Create/ByOutlineExtrusionTypeAndLevel), but the _[Roof.ByOutlineTypeAndLevel](http://dictionary.dynamobim.com/#/Revit/Elements/Roof/Create/ByOutlineTypeAndLevel)_ node works for me. Wombat has also a similar node called _ExtrusionRoof.ByProfile_. See this post optionally: > [@NewFootPrintRoof Troubles](https://forum.dynamobim.com/t/newfootprintroof-troubles/8624/3): > > You’re half way there. This is one of those parts of c# that are not easily convertible to iron python. Try the below instead: footprint = CurveArray() for o in outline: footprint.Append(o.ToRevitType(True) ) TransactionManager.Instance.EnsureInTransaction(doc) roofCurves = StrongBox[ModelCurveArray](ModelCurveArray() ) footprintRoof = doc.Create.NewFootPrintRoof(footprint, level, roofType, roofCurves) TransactionManager.Instance.TransactionTaskDone() OUT = footprintRoof.ToDSType(False),… ---

As suggested by @Yna_Db - you can download Wombat. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/d/2ddf966881975aba802fb5afed58d9a914243f82.png) I think the OOTB dynamo node is faulty since it gives me this weird error - that the polycurve is not closed. Indeed it shouldn’t be closed for an extrusion roof. The node from Wombat works fine for me. ---

Thanks Guys, its just strange that a built in node doesn’t work! and there is no enough explanation for the inputs…I think it would be a good idea if there was explaining videos or samples for the built in nodes when you hover over them ,same like when you hover over a Revit button for a while.
