So I have a bunch of elements that have a custom parameter assigned. I would to get all those items that have something filled out in those custom parameters. What would be the best way to go about that?
I was thinking that I could grab all the elements in the model and then filter them by if the parameter exists, and then again filter by whether there is something filled out or not. The first problem I ran into was under the revit>selection there was no select all elements, just all in categories, on levels ect… A work around would be to create node for each category combine the list and then flatten them, but that seems like a more work then should be required. Thanks.
