Linear Nesting: Bar Cutting

LINEAR NESTING — Smart cutting optimisation for bars and profiles.

Plan your cuts. Save material. Save time.

Linear Nesting is a professional cutting optimisation tool for anyone working with bars, profiles, pipes, or any linear stock material. Whether you are a metalworker, carpenter, plumber, glazier, or serious DIY builder, generate optimal cutting plans in seconds.


✦ FREE TO START, PRO TO UNLOCK EVERYTHING

Use the free version to plan real jobs: up to 10 pieces, two optimisation algorithms, and full visual and list reports.

Go Pro for the complete toolkit — a 7-day free trial, then an auto-renewing annual subscription, cancel anytime:
• Unlimited pieces
• All five algorithms
• PDF export (list and bars)
• CSV and Excel import
• Direct printing


✦ FIVE OPTIMISATION ALGORITHMS

Greedy and Balanced (free), plus Pure Knapsack, Hybrid Knapsack and Grouped (Pro). Each suited to different priorities — speed, raw efficiency, or grouping pieces by program.


✦ VISUAL CUTTING PLANS

Every plan shows clear bar diagrams with colour-coded pieces, saw kerf, and leftover indicators. Compare patterns at a glance.


✦ TWO REPORT FORMATS

• Visual bars — see each cut with proportional widths
• Compact list — text-only report, perfect for the workshop floor


✦ FOUR LANGUAGES

Full interface in English, Portuguese, Spanish and French. Switch anytime from the cover screen.


✦ FULLY CUSTOMISABLE PARAMETERS

Fine-tune to your real-world setup:
• Bar length
• Saw kerf (cut width)
• Initial and final cleanup cuts
• Maximum leftover threshold for piece swapping
• References-per-bar limit
• Automatic useful-length calculation
• Optional material cost estimate (weight per metre and price per kg)


✦ NO ADS, PRIVACY-FOCUSED

The cutting optimisation runs entirely on your device — no account, no sign-up, and it works offline. No advertisements, ever. The only information handled is your subscription status, which is processed securely through Google Play and RevenueCat when you choose Pro, and encrypted in transit. Full privacy policy is linked from the cover screen and from the Play Store listing.


WHO IS IT FOR?

• Metalworking and welding shops
• Carpentry and construction
• Plumbing and pipe cutting
• Window and door manufacturing
• Glass cutting (linear pieces)
• Aluminium profile fabrication
• Steel rebar work
• Anyone cutting linear stock material


HOW IT WORKS

1. Enter your stock bar length and cutting parameters
2. Add the pieces you need (length, quantity, reference ID)
3. Pick an algorithm and tap CALCULATE
4. Review the visual cutting plan
5. Recalculate with a different algorithm to compare
6. Export to PDF or print directly (Pro)


PRO TIP

Test several algorithms on the same job. Sometimes a 1% efficiency gain saves an entire bar — multiplied across hundreds of bars, the savings add up fast.
