How can I install Surface.Difference?

I saw other people using (Surface.Difference) but I can not find it in my Dynamo. Thanks in advance.

What Revit and Dynamo version are you on?

Hello, thanks for your response. Iā€™m using Revit 2020 and Dynamo Revit 2.1.0.7733.

Think it first comes with revit 2020.2 think its Dynamo 2.3 so if you are on previous version you dont see it :wink: you will need to upgrade, but there are other nodes there will do the job as well
