Create multilayer wall types from excel sheet (with new material)

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.

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.

Hi @bioand81,

To create several walls, set the longest lacing on the Create Compound FamilyType node.

Thank you so much for your response! It works.

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:

I edited it, but I’m getting an error where it creates new walls with the same thickness of 200 (it seems like it copied the thickness of the sample wall). Please help me!
