I've created fabrication drawings in the past using the layout editor, but some of the DocField global attributes like >sheet don't update. I decided to make my own DocField so I copied it to my library and edited it. Now I see my DocField element from the schematic editor, but not from the layout editor (using add command). Going back to the original frames library I see that DocField is visible in both editors. What needs to be done to my library entry to make it appear in the layout editor's Add command?
