Dear Andrew, thanks for you response!
Actually I´m trying to insert environmental evaluation (type) parameters in Revit Families, so I´d like to have something like a project history to see how such parameters are getting better or worse through my project life cycle and its solutions trade-offs. I think it would be good if every time I run my Dynamo file, the results would be exported to a new excel sheet.
If you have some example to show me, I think maybe you have a good solution for me.
Thanks a lot once more!
Cristiane
