Filtering Glazed (glass) panels

Goodday, I am trying to sift or filter through a project curtain wall panels to only get the glass ones. I tried to use the subcategory but it also failed (see attached). Is there an easy way to only select the glazed (or transparent) non-opaque panels only?

Hi Archmsyd,

You can get all glazed curtain wall panels by Type like this.

The other option is Analyze Curtain Wall and the Curtain Wall Grid to get just that walls Panel Types.
