Fusion 360 CAM simulation shows the toolpath. We simulate the G-code. Catch post-processor errors and machine collisions before Cycle Start.
Why do I need a simulator if I use Fusion 360? Fusion 360's built-in simulation verifies your toolpath before post-processing. Eureka3X is a dedicated Fusion 360 CNC simulator that verifies the actual G-code generated by your post-processor on a perfect digital twin of your machine.
💻 Windows 10/11 Required Eureka3X is a desktop simulator and cannot be installed on mobile devices. Send link to my email ➔

Trusted by professionals who can't afford mistakes
Eureka3X is built on Eureka Virtual Machining — 20+ years of industrial CNC simulation, used in production by world-class manufacturers.
Sound familiar?
These happen every week in every shop. Eureka3X fixes all three.
THE PROBLEM
Post-processor bugs
Fusion 360 simulates a perfect toolpath, but the post-processor generates an unexpected rapid move or cycle parameter.
THE FIX
Simulate the actual G-code
Eureka3X simulates the exact NC program that goes to the machine, catching any post-processor bugs.
THE PROBLEM
Machine-specific kinematics
Fusion 360 doesn't always know the exact physical limits and kinematics of your specific machine.
THE FIX
Full digital twin simulation
We simulate your exact machine model, catching overtravel errors and physical collisions between the spindle and the trunnion.
THE PROBLEM
Setup and fixture collisions
Importing heavy vises and fixtures into Fusion 360 can slow down your workflow and assembly.
THE FIX
Dedicated verification environment
Export your stock and tools to Eureka3X to simulate the entire setup in a lightweight, dedicated environment.

Frequently Asked Questions
+Why not just use Fusion 360's simulation?
Fusion 360 simulates the theoretical toolpath. Eureka3X simulates the actual G-code after it has been post-processed, which is what the machine actually runs.
+Do I need to export everything manually?
Eureka3X allows you to easily import stock and tool definitions from your CAM software to set up the simulation quickly.
+Does it support 5-axis toolpaths?
No, Eureka3X is specifically designed for 3-axis milling. If you need 5-axis continuous or 3+2 machining, as well as mill-turn simulation, or Swiss CNC simulation, please explore Eureka Virtual Machining on www.eureka-sim.com.
+What happens after the trial?
After 30 days, your trial will expire. If you want to continue using the software, you can upgrade to one of our plans. There is no automatic charge since we don't ask for your credit card upfront.
