Hi - having trouble getting this to work, maybe it can’t. I am collecting view types from the current documents (Area Plans) and counting the area lines in each view. It works for the current document but when I try to use views from another file (from a folder) I get the “viewid is not a view” error. Im assuming I will continue to get this type of error for other element and category types…

Thoughts?  
Thanks,  
Jason

The select by category and view node doesn’t have a document input, and as such it is getting the content from the active document.

Okay, makes sense. Thanks.

Hi Jason,

The _Genius Loci_ package has a bunch of nodes that work with document inputs.  
This version of the _SelectByCategoryAndView_ also works with linked views.
