CNC routers joined lasers and plasmas as first-class citizens:
- Tabs. Leave small uncut bridges on each part's profile so pieces stay in the sheet instead of dropping mid-cut. Hole-aware placement keeps tabs away from drilled features, and corner avoidance keeps them snappable.
- Router mode. Supply a cut depth and the G-code grows a Z axis: plunges at every profile, retracts over every tab bridge, and stepdown passes that split deep cuts into multiple depths.
- 3D NC viewer. Tilt and orbit the toolpath in 3D, with tab bridges sitting on the surface where they belong.
