Upgrading Models from "Revit (BDS) 2019" to Revit (AECC) 2020". Revit locks up after opening the file and has to be closed through the task manager. I have tried multiple files of different sizes and even ran audits on the files.
I had just purchased the AECC 2021 & BIM360. But currently need Revit 2020 to match other consultants. So downloaded and installed the Revit 2020 & the Advanced Steel 2020.
