Welcome to the Revit 2017 tutorials section. Autodesk Revit 2017 is now 1 version old since the release of Revit 2018.
Revit 2017 was released with many great features but perhaps the biggest to note was the inclusion of the new Dynamo Player that makes it possible for anyone to take advantage of the power of Dynamo scripts.
Revit 2017 also shipped with native Rhino file import and an improved SAT file import which can be really useful when collaborating with other disciplines or interfacing with other services.
Overall, Revit 2017 has some great new features and it is the preferred version to use here at Revit tutorials.
