There are 2 ways to duplicate an item in Gather.
1. From within an item:
Open the item you wish to duplicate
Click on the "Actions" dropdown in the top right corner of the item
Select "Duplicate"
Select the "project" and "Area"
Click the green "Duplicate" button
Wait for the 3 dots to finish generating and you see a green ✅
2. From the Library:
Open the Library
Find the item you would like to "duplicate" by using one of the filterings options (This is where your "Types" come in very handy)
Click on the item to open it
Select "Duplicate"
Select the "project" and "Area"
Click the green "Duplicate" button
Wait for the 3 dots to finish generating and you see a green ✅
Please note, you can only duplicate 1 item at a time from the "Library". However, you can duplicate multiple items from within a project. Learn more here Duplicating Multiple Items at a Time.
