Previous Versions

Is it necessary to keep previous versions of Revit (2015,2016) if you have 2017 installed?

Hi @Anonymous Welcome to Autodesk Community!

Not necessary. Unless you need the older versions, you don't have to keep them if you already have 2017 version installed.

I see you also posted in: Previous Versions of Revit and Natasha has answered your question as well.
