What is Smart2DCutting 3.5?

A lightweight, free nesting software that arranges 2D shapes (rectangles, circles, polygons) onto a larger sheet to minimize material waste. Used for CNC, laser cutting, woodworking, and metal sheet optimization.

4. Compatibility

Version 3.5 is known for its stability. It runs smoothly on older versions of Windows (like Windows 7 and XP) as well as modern systems (Windows 10 and 11), ensuring that it fits into your existing IT infrastructure without requiring hardware upgrades.

1. Advanced True Shape Nesting

Unlike basic rectangle packing, version 35 analyzes actual part geometry. It nests concave polygons, circles, and organic shapes inside each other's negative spaces (interlocking).

Tips for Maximum Efficiency

| Setting | Recommendation | |--------|----------------| | Rotation | Allow 90° – 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. |

Pro trick: Group identical parts → increase quantity instead of adding separate entries.
