Hey there,

Is it possible to use the FamilyDoc.Parameters (Crumple) node with multiple families from a directory? I’m not sure if this is even possible or if I need to add some extra nodes in between to make this work. I would like to get the data of all the parameters in multiple families at once.

You have to provide the `familyDocument` to the parameters node. This means you’ll likely have to open those families in the background so that you have a document to query.

I can confirm Nick is correct. Use FamilyDoc.Open and FamilyDoc.Close to open/close files in background. You will also need to set some of those nodes to levels (typically levels 1 or 2) depending how you want them to work. The python is all exposed inside so you can see how it works with looping the inputs.

Hi @alshammary.l  
Were you able to export the parameter data from multiple families into a single excel file ?  
If so, could you share the workflow a bit if possible?

The wip Crumple on github has nodes that can do one/many to achieve this type of workflow. I will be releasing it in a month or so with some example workflow scripts also.
