Reload Multiple Families

The families already exist in the project, I want to reload them with new versions.

I can select multiple families through the Revit Load Family command, but Revit asks if you want to overwrite for each family.

I have a lot of families (109) that have lots of instances (3,500) so I sit waiting for minutes for each family to load and Revit to regenerate.

I know Dynamo won’t make Revit go faster but I could line up all my families to reload with no user input I could at least go and have a coffee (or boozy lunch, it literally takes hours).

 

Use this, comment out the change parameter stuff if you dont need it.
