What is the difference between the Board Geometry / Outline and Board Geometry Design Outline, which is most preferable while creating a PCB board.

Hai community,

I had a doubt, when i am creating a Board Geometry outline, i can seen 2 different subclass in Version 17.4 onwards, which will be more preferable for PCB board creation, is it just the outline or is it better to use the design outline as the subclass, also should i use the cutout also along with the Design outline subclass.
