How do you know if they’re unnecessary? No value?

correction. I want to remove all parameters of a family that has been put by a manufacturer to place our parameters

Don’t know if someone has it. Let me know how the one your making goes.

More than anything I’m wondering how you’d find these specific parameters via Dynamo in the first place.
Also: why do you want to?

Try dowloading “DanEDU” package and using its “FamilyDocument.RemoveParameter | DanEDU” node

Or if you have some python knowledge you cant start from looking here:


Thanks @GregX for the reference,

It is certainly doable to remove parameters in a family, just run the node @GregX suggest, and if you want to do it in a range of files, then combine it with openDocument / closeDocument nodes from @john_pierson Rythm package.

There are several posts showing how to work with bulk work on families. I made that series of nodes for purposes like yours and many others in addition.

here is an overview of the family nodes


Perfect !! thanks !!!

If a comment solves your problem please mark it as solved (and maybe leave a like here and there).



sorry to interfere, but it is actually not me who should have the credit, it is @GregX :slight_smile:
