Have you been able to find the extension? I am also looking for it.
Guys. You can just copy the add-in files from the 2019 add-in folder to the 2020 add-in folder and it will work just fine.
Ok, I did that but I still do not have access to print reports like I do in 2019. Do you know what add-in control that?
It should be the RevitFabricatoinExtension addin. Make sure when you copy it you copy all 3 files for the addin and not just the ADDIN file alone.
Extension is finally out for 2020. Check your Desktop App or account portal.
