SigmaNEST Review 2026: AI-Assisted Nesting and Cutting for Sheet Metal Shops

Updated October 13, 2026 – Tested Intelligence

Quick verdict: SigmaNEST is the serious programmer’s nesting software: it lays out parts on sheet and plate for laser, plasma, waterjet, oxyfuel and punch machines, generates the NC code, and now answers questions inside the program through SigmaTEK Copilot, an AI assistant powered by Microsoft and OpenAI. The company behind it, now renamed SigmaTEK, says it serves more than 23,000 customers in over 50 countries. Pricing is not public, so this is a quote-first purchase.

What it is

SigmaNEST, from SigmaTEK Systems (part of the Sandvik group), is CAD/CAM nesting and NC programming software for fabrication shops. If your shop cuts duct fittings, brackets, panels and plate all day, the money is made or lost in the nest: how tightly parts pack onto a sheet, how much remnant is left, and how fast a programmer can turn drawings into machine-ready code. SigmaNEST automates that layout work and drives nearly every major cutting, punching, routing and combination machine.

The AI piece is Copilot, introduced with SigmaNEST 25 and expanded since. Copilot sits inside the software and on the Connect portal for users on a maintenance plan, answering process questions – CAD import tips, geometry editing, licensing – in 19 languages, around the clock. The October 2026 V27 announcement goes further, with Copilot able to perform actions in the software, more than 200 of them, for maintenance-plan users.

Key features

• TrueShape and HD SuperNest automatic nesting for sheet, plate and tube
• NC programming for laser, plasma, waterjet, oxyfuel, punch and combination machines
• SigmaTEK Copilot AI assistant, powered by Microsoft and OpenAI, in 19 languages
• Copilot in V27 can perform 200+ actions in the software (vendor announcement)
• Develop module unfolds common sheet metal fittings – cones, elbows, reducers, transitions – for HVAC and duct work
• CAD import from major 2D and 3D systems, plus quoting, inventory and shop-floor modules in the wider suite

Pricing

Pricing is not public. SigmaTEK does not publish license or subscription figures, and directories list no price information for SigmaNEST. Expect a quote based on the modules, machines and seats you need, plus a maintenance plan – note that Copilot access is tied to being on that plan. Judge the quote against material saved per month and programmer hours freed, because yield is where this software pays.

Who it’s for

Sheet metal and plate shops running CNC cutting or punching equipment – including HVAC duct shops cutting fittings at volume – where a programmer’s day is spent nesting and where a few points of material yield move real money. It also suits shops standardising on one CAM system across several different machine brands.

Who should skip it

Shops that hand-cut or outsource their cutting: there is nothing to nest. Very small shops with one machine and a simple, bundled CAM package they already know should also think hard – SigmaNEST’s depth, and a maintenance-plan sales model, are built for shops with steady programming volume, not occasional cutting.

Pros

• Best-in-class nesting depth across almost every cutting process and machine brand
• Copilot gives programmers instant, in-program answers instead of support tickets
• Develop module speaks duct-shop language: parametric fittings and flat patterns
• Proven scale: 23,000+ customers in 50+ countries (vendor figure)

Cons

• No public pricing – everything goes through a sales quote
• Copilot needs an active maintenance plan, so the AI is not a free add-on
• Full suite is a lot of software to learn for a small shop
• Copilot performs actions in V27, but the core nesting engine is proven algorithms, not generative AI – set expectations accordingly

FAQ

What machines does SigmaNEST drive?

Laser, plasma, waterjet, oxyfuel, punch, router and combination machines from most major builders, for sheet, plate, tube and profile work.

What is SigmaTEK Copilot?

An AI assistant built into SigmaNEST 25 and later, powered by Microsoft and OpenAI. It answers product and process questions in 19 languages, and in V27 can perform more than 200 actions in the software for maintenance-plan users.

How much does SigmaNEST cost?

Pricing is not public. Expect a custom quote based on modules, machines and seats, plus an annual maintenance plan.

Bottom line

SigmaNEST is the nesting benchmark for shops that cut sheet for a living, and Copilot makes its depth easier to use – especially for newer programmers. Get the quote, measure it against your scrap bin and your programming backlog, and make the vendor prove the yield on your own parts.
