Same parts, higher material utilization
Manual layout wastes space and needs rework. Smart nesting searches layouts and keeps improving utilization. Both sides below use the same real parts: left is a simulated experience-based layout, right is a real solved layout.

Drag the divider (or focus it and press ← / →) to compare both layouts
Both sides use the same real parts: the right side is the system's real solved layout (all parts on one sheet), the left side is a simulated experience-based layout (only part of the batch fits the same sheet; the rest needs extra material).
One pipeline from drawing to cutting
Upload → geometry preprocessing → nesting solve → visualization → export (SVG / DXF / PDF / NC).
Geometry Preprocessing
- Validity check & closure detection
- Area / bounding box / interior stats
- Automatic convex decomposition
- Clear errors for invalid files
Nesting Algorithm
- NFP + rotation discretization
- BLF + critical-position enumeration
- GA + SA hybrid optimization
- No overlap / no out-of-bounds
Production Constraints
- Kerf compensation
- Grain direction / rotation limits
- Small parts nested into holes
- Pattern matching / common edge & bridging
Output
- SVG / DXF / PDF nesting drawings
- NC cutting code (G-code)
- Utilization reports
- Excel part details
Platform
- Browser based · asynchronous solving
- Job list + personal part library
Algorithms drive the layout, precision in every millimetre
Geometry layer judges precisely, layout layer places fast, optimizer searches globally — three layers working together. The gauge below shows utilization of real solved results (not sample values).
Geometry layer
NFP + rotation discretization + collision detection: exact intersection tests, automatic convex decomposition, rotation over allowed angles.
Layout layer
BLF + critical-position enumeration: sort by area, enumerate critical positions and place the best bottom-left candidate.
Optimization layer
Genetic algorithm + simulated annealing (GA+SA): sequence and rotation as genes, tournament selection + PMX crossover + SA local search.

Results & download
Zoom / pan the layout, export SVG / DXF / PDF / NC and utilization reports.
Industry capabilities for efficient production
Ready-to-use parameter presets and outputs for each industry constraint.
Steel Cutting
Common edge, bridging and splitting for thick plates: shorter cut paths, less waste.
Garment Cutting
Grain direction and pattern-matching constraints keep the finished look consistent.
Sheet Metal / Laser
Complex concave shapes and holes, exported as standard NC code.
CNC Plasma
Kerf compensation offsets along the contour: controllable cutting accuracy.
