data model: layers | copper, silk, mask, paste, plated route/cut, unplated route/cut, arbitrary documentation/misc layers
data model: padstacks | holes, slots, blind/buried vias, different shape on different layers (including non-copper layers), arbitrary polygon shape
data model: footprint | any object and layer supported in footprint; rich metadata; option for run-time generated footprints
data model: netlist | named networks, rats nest, deliberate netlist changes + back annotation
netlist support | draw using netlist/footprints imported from schematics back annotation to schematics editor alternatively create netlist from scratch while drawing the PCB altnenatively draw without netlist
DRC | powerful, user scriptable DRC that has full access to all board data (including logical such as networks and physical such as layer stackup and object geometry)
