Hi @braicodavid
A schedule runs off of 'Categories'. So in order for all of your kitchen items (for instance) to be in the same schedule, they all need to be under the same 'Family Category and Parameters'.
Once all of your items are under the same category, when you create your schedule you will have to work out what 'Available Fields' you want. Lets say you chose 'Mark Type' and 'Description', once you choose those two things, that then gives you a indication what fields you need to fill out in your family parameters.
Then you can tag those items on your drawings.
Hope this somewhat helps?
Thanks
