KiCad layer for the physical board outline. Lines drawn here define the shape JLCPCB will cut.
How it looks
Real geometry: CORE3588 copper, drawn from our board file (2D plan view)
Top copper of CORE3588 plus its Edge.Cuts outline (amber), drawn from the board file.
1The Edge.Cuts outline of CORE3588: one rectangle, 86.5 x 101 mm. The fab cuts the board out along this line.

The finished shape (KiCad 3D render, top). Everything outside the outline is scrap from the fab's panel.
1Some camera connectors deliberately stick out past the edge, so the cable can plug in.
How it works
Where it fits
Edge.Cuts goes to the fab as its own Gerber file. It is one of KiCad's non-copper layers, like silkscreen; copper lives on F.Cu, B.Cu and the inner layers.
