Hi all,  
I have 100+ families, is it possible to automatically delete only parameters with empty value and parameters with 0 value?  
Probably this is the way: [How to delete multiple family parameter from inside the project - #5 by MJB-online](https://forum.dynamobim.com/t/how-to-delete-multiple-family-parameter-from-inside-the-project/26802/5) but I don’t know as to filter parameters.  
Note: I have both 100+ individual families and all 100+ families loaded in the rvt file and no shared parameters.  
Thank you.

deleting families = possible  
deleting parameters = not possible (if it’s built-in parameter)  
deleting parameter values = possible (but it means make it empty)  
which one you want? a bit confusing.

Because I want a report (i.e. spreadsheet) where are present only “non empty” value parameters.  
For example if you have 3 params, the first with value A, the second with value B and the third with empty value, in report i want only the first and the second parameters
