Hello, I saw a previous post about applying _List.Map_ to the node _Tool.Create.Assembly_ I tried to do the same; but unfortunatly it doesn’t work. Any ideas for how to fix this? I have hundreds of family instances, and I need to create an assembly for each family instance. Thank you in advance. ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/7/a733a27c8a57eb8639181376d495c2e884a373de.PNG) ---

Hi Ahmad, Is this the topic you are refering to [link] ? I think you need to add te “Transaction.End” node, like @Dimitar_Venkov did. I hope it helps. ---

Hi @MJB-online, thanks for your reply, I tried this out, but the issue is that I want to create an assembly for each family instance; for my example, if I have a 4 family instances of the same family type, so I want 4 assemblies. Please check this GIF: ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/4/d49d36a0044472f44a34e5be9e2cde7beeda05e7.gif) ---

Hi Ahmad\_Saad, If the family instances are identical Revit is aware of that, and creates 4 identical assembly instances, and they all get the same name. Thats the way it works, as far as i know. ---

Thanks for your reply. I think the problem was the selection method, I used another way and it worked: ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/9/396d1195e311796ab0534e6b4b45e48d4ce63b4b.PNG) ---

Hi Ahmad, I’m curious what happens if you add the “Transaction.End” node to the **top/pink** workflow. You’re now feeding the “List.Map” node with three different family types. Last time the family types were identical as far as i could see from your GIF. Kind regards, Mark
