Nesting Studio
2D Nesting Algorithms — Cut Waste, Boost Yield
Fast greedy plus optimized nesting for DXF sheets—many jobs reduce scrap 20%+ vs naive layouts; results vary by job.
Switch between rapid bottom-left packing for quotes and deeper optimized passes that squeeze more parts per sheet. On comparable DXF jobs, many teams see scrap fall 20% or more versus simple row or grid placement—actual uplift depends on geometry, stock, and constraints. Parallel workers keep long jobs moving while you monitor progress from the dashboard.

Fast ModeAlgorithm
How fast mode generates high-quality layouts in 2-3 minutes
Part Sorting
Sort parts by area (largest first)
Parts are sorted in descending order by their area. Larger parts are placed first, which helps create a stable foundation for smaller parts to nest around.
Bottom-Left-Fill
Greedy placement starting from bottom-left
Each part is placed at the lowest available position, then moved as far left as possible. This creates a compact layout by filling from the bottom-left corner upward.
Collision Detection
Fast bounding box checks
Uses efficient axis-aligned bounding box (AABB) collision detection to quickly determine if a part can be placed at a given position without overlapping existing parts.
Rotation Testing
Try multiple rotation angles
Tests allowed rotation angles (0°, 90°, 180°, 270°) for each part to find the best fit. Rotation is determined by part classification and user preferences.
Sheet Iteration
Place parts across multiple sheets
When a sheet is full, remaining parts are placed on the next sheet. The algorithm continues until all parts are placed or no more sheets are available.
Result Generation
Generate final layout and statistics
Returns the complete nesting solution with part placements, sheet utilization statistics, and any parts that couldn't be placed. Results are ready in seconds.

AlgorithmFeatures
Key techniques powering fast mode nesting
Bottom-Left-Fill
Greedy placement strategy
Places parts starting from bottom-left corner, moving right and up. Fast O(n²) algorithm suitable for quick layouts.
Area-Based Sorting
Largest parts first
Sorts parts by area in descending order. Larger parts create a stable foundation for smaller parts to nest around.
AABB Collision
Fast collision detection
Uses axis-aligned bounding boxes for quick collision checks. Efficient O(1) per pair comparison.
Rotation Testing
Multi-angle placement
Tests allowed rotation angles (0°, 90°, 180°, 270°) to find optimal part orientation for better fit.
