Find/Replace or If/Then?

I am using Dynamo to concatenate multiple parameters related to Revit pipes and I have that part working. One of the parameters is “Size”. What I’d like to do is a find/replace to change the size format in my concatenated parameter.

Revit size --> Desired output

8" --> 08

12" --> 12

30" --> 30


Is there a way to create an if/then or find/replace type of code to modify these values in my concatenated parameter value? I could easily create a list of all of the possible sizes, but not sure how to go about this in Dynamo.


Thank you,


Hi Jason, Below is another method.

Thank you Vikram and Kulkul! I’ll see if I can get this to work.
