This article provides information on how to create an assembly item using Authoring Hub.
In the following example, a lounge sofa will be built. To build it, we will use three items in its composition.
Now that these items are separated, we can access the main item lounge_set. And in the Definition tab, we will add all the sub-items.
To add a sub-item, we have to set its itemRef (you can find this value in the Code column under Items), define its position and dimensions as you want, and repeat this process for all necessary sub-items.
After entering the three sub-items, you will have the result of the complete assembled sofa.
