Extract Lookup table of Family OR parameter value derived from the Lookup table

Revit
1

Hello,

I’m looking for a way to extract a Family’s parameter values that are derived from the lookup table linked to the Family. Is there a way to access the lookup table data through Dynamo OR preferably extract the parameter value that changes by the lookup table?

For example, a valve Family’s length is set by a lookup table, which uses the pipe nominal diameter as input. So if pipe dia=400 -> valve length=216, pipe dia=500 -> valve length 285 or something.
Right now I can only get the value only if the Family instance is created inside Revit. But I want to know the value without creating a Family element. The Family and Family type will be given as input.

Any advice would help!

Thanks.

hi @Soojung.Kim

If you know how to code in python/c# you can access lookuptable here: FamilySizeTableManager

Hi, thanks for the reply.
I’m not a coder so not clear how I would code that, but I’ll look into it.

Thanks!
