Thank you for your reply.
I'm currently using Revit 2019 because the project they gave me is modeled in that version of the software, and ArcGis Pro 2.7, so the latest version.
I did not create the parameters, but the ones i'm interested in are all created as project parameters, in the attached pictures you can see them because they have the name starting by Cod_xxx, and as you can see these "Cod_xxx" parameters are both in the instance parameters both in the type parameters.
I was wondering why those are not visualized in ArcGis Pro because i have to add other parameters later in Revit to figure out when selecting an object in ArcGis Pro, so i was wondering which was the logic of the software on importing parameters on ArcGis Pro. Thanks in advance
