Filtering furniture category families by type parameter name

[r-eto]

I was wondering if there was a way to filter all families that are furniture category with a certain parameter name from the types?

I was able to collect all furniture families but didn’t know what to do next?

Could you use GetParameterValueByName node and then filter out nulls which should be the ones without the param.

Thank you for the reply.
I’ve tried this but still having problems.

You are running it against each instance, but it’s a type parameter. You need to get the Element type from each instance and then get the parameter.

Thank you Sean. I’ll look into it.
