Hi,

I’m trying to find a node or python code to flip a bunch of doors flipped in the same way to the other way.  
I have searched in this forum but I don’t find.  
Is it possible to do it in Dynamo?

Hi @blsalvio,

Thank you for helping. I would like to use a “select model elements” to flip only the selected doors.

hi @JC.Moreno

You can customize the dynamo script. Just pass list of doors in the input of python 🙂
