Smart2DCutting 3 is a 2D panel-nesting software tool. It uses advanced algorithms to calculate the most efficient way to cut smaller parts out of large rectangular sheets (like plywood, MDF, glass, plastic, or metal sheets).

But for with a mature free desktop app, Smart2DCutting 3.5 remains a solid choice.

I can recommend the safest, most efficient tool tailored to your exact production needs.

| Setting | Recommendation | |--------|----------------| | Rotation | – faster computation, nearly optimal for rectangles. | | Part gap | Sheet thickness + 0.5 mm – prevents fusing on laser/plasma. | | Kerf | 0 mm for design – add kerf in CAM post-processing. | | Edge margin | 5–10 mm – clamps/rollers need space. |
