Adding formula to multiple families

Could you help me out with the packages i have to install to add value in multiple families ??

Hello,

You’re going to need to be more descriptive on what you’re looking for. Are you sure that this isn’t something you can do with basic Dynamo?

If you can, please share a screenshot of what you have been trying to work with, or at the minimum what ‘value’ you are looking for. Do you mean parameters?
