CAD/CAM software with AI features in 2026: which tools have AI agents or assistants
Most of the big CAM packages have some AI in them now, and a second group of tools plugs AI toolpath generation into the CAM you already use. Mastercam has Copilot, which runs commands you type or say. Siemens NX suggests how to machine a feature when you click on it. ESPRIT EDGE has ProPlanAI for process planning, and Cimatron has a CAM Agent for 3-axis toolpaths. CloudNC CAM Assist, Toolpath, Limitless and up2parts autoCAM generate the toolpaths for you inside a host CAM. KinetiCAD plans and programs the whole job from the model and the drawing without a CAM seat.
I build KinetiCAD, so I have a side here. Every claim about another product links to the page I read on November 10, 2026, or for a few earlier checks, November 4.

Assistants and agents
These words get used loosely, so here's how I use them.
An assistant helps you drive the CAM. You ask it something and it answers, or you tell it what to do and it does it. Mastercam Copilot fits here. You can tell it to change the spindle speed on every operation, or say "Copilot" and talk to it while your hands are on the mouse. The NX chat copilot answers questions such as how to change the non-cutting moves on a cavity mill operation.
An agent looks at the part and proposes the program. It picks setups, tools, operations and toolpaths, and you review the result and post it. CloudNC CAM Assist, Toolpath, Limitless, the Cimatron CAM Agent and up2parts autoCAM all work this way. They differ mostly in which CAM they run in and which machines they cover.
NX's Make Machining Suggestion sits in between. You click a face or a feature and it offers ways to machine it, with operations, tools and parameters filled in. Siemens says it learns from the choices you make, so over time the suggestions follow your shop's habits.
What the big CAM vendors ship
Mastercam. Copilot became a full release in Mastercam 2026.R2 and is a free update for customers on Mastercam CONNECT maintenance. It can build a machine group and add operations from one instruction, and Mastercam says support for over 200 toolpath types is coming. For work plans and quotes, Mastercam works with up2parts (Mastercam).
Siemens NX. Feature-based machining has been in NX for years. It recognizes features and applies operations from a library you can teach. On top of that come Make Machining Suggestion and the chat copilot. Partners in the NX ecosystem add more, including Manukai and the free Lambda Function plug-in (Siemens).
Autodesk Fusion. Fusion automates hole drilling through hole recognition, and it automates surface finishing with steep and shallow. Autodesk calls automated CAM programming an area it's exploring. For AI toolpaths today, Fusion users install CloudNC CAM Assist or Toolpath. Autodesk has invested in both (Toolpath, CloudNC).
Hexagon ESPRIT EDGE. ProPlanAI does automated process planning. You train it on programs your shop already wrote in ESPRIT, so it needs a body of past work to learn from.
Cimatron. The Cimatron CAM Agent, shown at IMTS 2026, generates complete 3-axis toolpaths. It was built with Limitless.
Add-ons that write the toolpaths
CloudNC CAM Assist runs in five CAM systems and covers 3-axis and 3+2 milling. CloudNC says lathes and mill-turn are in development. Its plans are sold by credits per month. CloudNC also sells Quote Agent, a separate app that prices parts, including turned parts.
Toolpath is Fusion only. It combines quoting with automated 3-axis and 3+2 toolpaths, and the CAM part is in the Pro plan at $125 per seat per month billed annually, or $160 month to month.
Limitless runs inside Mastercam, NX and Creo and is aimed at larger manufacturers. It models cutting forces and tool wear and checks 3+2 and mill-turn kinematics for collisions.
up2parts reads the 3D model and the PDF drawing, builds a work plan and a quote, and autoCAM finishes the CAM program for milling machines in Mastercam or GibbsCAM. More detail in our up2parts comparison.
Where KinetiCAD fits
KinetiCAD is software for CNC job shops that turns a customer's STEP model and PDF drawing into a planned, programmed and priced job. It reads the tolerances and notes on the drawing, plans the operations across your own lathes and mills, writes the NC programs, simulates each one against the CAD model, and builds the quote from that same plan. Your team reviews and releases. It runs on local servers, with no external LLM APIs.
The other tools in this list need a CAM seat and a programmer to drive them. KinetiCAD is for shops where the person quoting is also the person programming, or where parts go from a lathe to a mill.
Questions to ask in a demo
- Bring one of your own parts with its drawing, not a demo part.
- Ask which machines it covers today. Many tools stop at 3+2 milling.
- Ask what it does with the drawing. Does it read tolerances and thread callouts, or only the model?
- Ask how the program gets checked before it reaches the machine, and who signs it off.
- Ask what the total cost is, including the host CAM licence.
If you want to see it on your part, send us a STEP file and its drawing.

Frequently asked questions
Which CAD/CAM software offers AI agents or assistants?
Mastercam has Copilot (2026.R2), which takes typed or spoken commands. Siemens NX CAM suggests machining approaches for a selected feature and has a chat copilot. Hexagon ESPRIT EDGE has ProPlanAI for process planning, and Cimatron has a CAM Agent for 3-axis toolpaths. Add-ons such as CloudNC CAM Assist, Toolpath, Limitless and up2parts autoCAM generate toolpaths inside a host CAM. KinetiCAD plans and programs the whole job without a CAM seat.
What is the difference between an AI assistant and an AI agent in CAM?
An assistant answers questions or runs the command you ask for, like changing feeds on five operations. An agent takes the part and proposes the whole program: setups, tools, operations and toolpaths. You still review and post it.
Does Autodesk Fusion have AI toolpaths?
Fusion has feature recognition for holes and pockets and automation for steep and shallow finishing. Autodesk has said automated CAM programming is an area it is exploring. Today the AI toolpath options in Fusion come from partners such as CloudNC CAM Assist and Toolpath.
Is AI CAM software good for 3-axis machining?
Yes. 3-axis and 3+2 milling is where most AI CAM tools started, including CloudNC CAM Assist, Toolpath and the Cimatron CAM Agent. Turning and mill-turn support is less common.
Do I need a CAM licence to use AI CAM tools?
For most of them, yes. Copilots and agents run inside Mastercam, NX, Fusion, GibbsCAM, SolidCAM or Creo, so you need that licence too. KinetiCAD generates the NC programs itself and doesn't need a CAM seat.
