Buongiorno, sto provando a creare muri multilayer con il nodo _Create Compound FamilyType_ partendo da un file excel. Ho realizzato lo script allegato ma sono riuscito a creare più muri monostrato, un muro multilayer ma non riesco a creare più muri composti da più strati. Successivamente vorrei provare a creare in automatico i materiali che non sono già presenti nel modello ma per ora sarei già felice di riuscire a creare i muri. Sono agli inizi con Dynamo quindi mi scuso per gli eventuali errori banali. Google Transalte: Good morning, I’m trying to create multilayer walls with the _Create Compound FamilyType_ node starting from an excel file. I made the attached script but I managed to create multiple single layer walls, one multilayer wall but I can’t create multiple walls composed of multiple layers. Later I would like to try to automatically create the materials that are not already present in the model but for now I would already be happy to be able to create the walls. I’m new to Dynamo so apologies for any trivial errors. ![2022-02_BeB_Prova wall from excel da GeniusLoci_02_2023-02-15_10-19-16](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/f/df01b6fe219efe0a7cbe0a24bdf3e0cc5e775655.png) [2022-02\_BeB\_Prova wall from excel da GeniusLoci\_02.dyn](https://forum.dynamobim.com/uploads/short-url/9S51xQ5NDS4xbwYG24M609FZJ8R.dyn) (42.4 KB) [Muri.xlsx](https://forum.dynamobim.com/uploads/short-url/2b9103LTCtf1ZLiXYXX18vx79Cz.xlsx) (11.1 KB) Related post: > [@Create wall types from excel sheet](https://forum.dynamobim.com/t/create-wall-types-from-excel-sheet/36812): > > Hi, I created a graph that collect wall thicknesses from excel i need to create thus types of basic wall family what is the simple way to do it? and how to remove duplicate thicknesses from list? ---

Hi @bioand81, To create several walls, set the longest lacing on the _Create Compound FamilyType_ node. ![2022-02_BeB_Prova wall from excel da GeniusLoci](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/6/3619e577458c49ca6f8eaf116bf1b617682d28ae.png) ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/a/fa6352d0877c2877844f020e8b711e20810b73a8.png) ---

Hi @Alban_de_Chasteigner , if the wall already exists is it possible to modify its layers by overwriting it? ---

I believe the compound structure can be reset using this method: > **[SetCompoundStructure Method](https://www.revitapidocs.com/2023/45f77d1a-c538-6fd2-7649-e461e66efbdd.htm)** > > Online Documentation for Autodesk's Revit API: 2015, 2016, 2017, 2017.1, 2018 ---

Please help me!
