i am fairly new to revit and now everytime i do a search for help it sends me to the autodesk store? my problem i am having in the overall view it shows all my duct work everything looks fine, but when i go to the views to put on the sheet it is missing every other piece of duct. i was wondering if there is a way to update the filters or for some reason duct work that i may have moved or created myself may not be on the filter list? and i have to have this drawing done by tomorrow morning
