Hello everyone, I have created a revit family which consist of cylinders placed on top of each other where all the cylinders thickness varies. So now I have thickness values in my excel. I am using dynamo to extract these parameter to revit to change the thickness accordingly. I have tried few ways, but no luck. Please help me with this. Regards, Satish J ---

Show us what you have so far. Your family needs to have parameters assigned to each cylinder thickness and then you can just modify those values accordingly. ---

Hello, thicknesses vary according to each type? ---

you don’t necessarily need a dynamo for that maybe an alternative solution is to use the Lookup Tables (especially if you already have a database) > **[About Lookup Tables | Revit Products 2018 | Autodesk Knowledge Network](https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2018/ENU/Revit-Customize/files/GUID-91270AEF-225A-49D7-BF84-1F44D1E3E216-htm.html)** > > Lookup tables are used for pipe and conduit families to define parameter values in an external comma-separated values (CSV) file.

@satishj013 You can also look at the [BIM One Excel import and exporter](https://apps.autodesk.com/RVT/en/Detail/Index?id=6290726048826015851) for tasks like this one.
