is it just me? i’m using Revit 2018.3 and Dynamo 2.0.1

well, perhaps my Dynamo Core is corructed, but Uninstall is greyed out, and i cannot install 2.0.0 back even if i deleted C:\Program Files\Dynamo\Dynamo Core\2

for uninstalling 2.0.1 try this:

thanks Michael.

anyone can confirm that OOTB Element.BoundingBox doesn’t work on Revit 3D view’s Section Box? i tried different version of Revit and Dynamo, don’t know if Python or C# will work
