At the risk of spoiling the purity of your ignorance @Box:
Layers in typical 2D CAD applications do not separate/isolate geometry.
Geometry in those CAD applications is, by nature, separate.
The opposite is true of SU’s “sticky” geometry which melds together upon contact.
The core function of Layers, controlling visibility, is the same in 2D CAD and SU.
The difference between CAD and SU is the fundamental behavior of geometry, not layer behavior.
