Lets say you want to make a "grouped" unit so that every time you want to order an item you don't have to individually enter each panel into MaxCut. You can with Grouped Units.
How it works...
1 - Make a Group let's say... F300
2 - Add the parts that build a F300 in parts (EG Side Left 720x560 - White Material [Tag - Exposed Left]) and so on
3 - Right click on the parent Group F300 and Click Save to Library
This item will now be accessible for reuse in the future.
