Reproducible benchmarks

Inputs, results, and limits—not a vague speed claim.

These repeatable cases show what both planning modes return from the same inputs. They test geometry and cut constraints; they do not prove superiority for every project.

Comparison results

Same inputs, two different cutting constraints.

Free Nesting and Guillotine Cutting answer different questions. N/A is deliberate when a geometric nesting result has no valid through-cut metric.

Method

How to interpret the comparison.

Same inputs.Each case uses identical stock, part dimensions, quantities, kerf, margin, and rotation settings in both planning modes.
Repeatable results.Every case is recalculated from its stated inputs and checked to return the same valid layout on repeated runs.
What we measure.Both modes report sheet count, material yield, and unplaced parts. Through-cut plans also report cut count, cut length, and kerf loss.
What this does not prove.These cases do not represent every material, machine, grain constraint, CNC toolpath, or workshop practice. Device-dependent runtime is not presented as a product claim.

See the constraint, not just the table.

Switch among the visual examples and inspect the layouts produced by both modes.
