Easy linked duplicates

If you know the dimensions of your collection (which are easy to find out using the "N-panel" under "Items") you can do:

• ALT-D on the collection --> press "Y" for the Y-axes --> enter "16" if your collection is 16 units wide (which it is in the video)
• This will place the duplicated collection to the correct spot
• Then press Shift+R to repeat as many times you want.
