Add a value to all floor nodes

Hi,

Can a script in dynamo be created to add a given value to all floor nodes?

We have many floors modelled for external works and we need to increase all the floor nodes by 120mm. Each node currently has a different value, so selecting each node and modifying the value or using a =1200+120 code in the value is extremely time consuming. Can Dynamo script help with this issue by adding 120mm to every node to selected floors in the model?

In any normal situation we would just need to modify the base point or Level but not this time unfortunately! :frowning:

Should be doable - what have you tried so far?

Do you have a small sample dataset?
Revit version?
Etc.
