Hi all. I am a student who wants to learn Dynamo. And I’m learning to set up a formula [image] So i tried to use node, and it worked However, there was a problem. I want to set up a lot of families at once. There are more than 100 things I want to do next. So my main question is How can i set Formula Various families at once What is difference “Autodesk.Revit.DB.Document” and “Revit.Application.Document” oh… I can upload only one capture… Sorry for my poor English and “Thanks”, Kitamura

Hrm yeah I’d go query erfajo over on Orchid as he might have changed the levels of that node since I used it. Its one of the reasons I started building my own familydoc nodes in Python, just needed consistent behaviour.

Hi @Kitamura and welcome, check this post to help you in your task, get the families from a directory or by category, edit them or background open them, check which one works for you, set the formula then save the families: [image] Split family types Revit Maybe something likes this? Packages used Clockwork and Orchid, it was done for only one family, for multiple families maybe a better lists structure is required. [Capture]

Thank you for your help. I think I can refer to it somewhere else But I want to set formula all Families at once, not split file… [image]

Whilst some of my nodes are old so have went into an unfound state, this is my script structure I use for batch setting of family formulae typically. Maybe it helps: [Set values batch_2022-05-30_10-31-28]

Thanks for your help. Maybe I can find hint from your script [image]
