Following a tutorial called Dynamo-Revit-Project-Setup on Lynda.com by Ian Seigel. The problem is on the section Import data for levels into Dynamo. The author calls out by going to the Library and select the Office, Excel and choose Excel.ReadFromFile. I dont have that choice. There is no Office (yes Office is installed) or Read from file option. I searched the packages and found Excel.ReadFromFile and installed it. After restarting Revit, I still cant find that option even though its installed. Can someone help? Basically cant proceed any further. Using Revit 2020, Dynamo 2.1. Many thanks in advance.
