The Path Simulator.svg Simulator tool allows Simulation of the Path Job by sweeping 3D Models of the Tools used in each Operation, along the G-Code paths, subtracting material from the Stock, where the stock and tool overlap, providing visualization of the Job. This allows detection and isolation of errors prior to running the Job on a mill.



  1. There are several ways to invoke the command:
    • Press the Path Simulator.svg Path Simulator button.
    • Select the Path → Path Simulator.svg CAM Simulator option from the menu.
    • Use the keyboard shortcut: P then M.
  2. De-select any Operations that are not to be simulated
  3. Tune the Speed and Accuracy settings.
  4. Select the Job for simulation from the drop menu.
  5. Use the Path Simulator toolbar to invoke different actions:
    • Press the Path BPlay.svg (Play) button to play or playback an animation of the operations.
    • Press the Path BFastForward.svg (Fast Forward) button to increase the speed substantially (in order to quickly review complicated paths).
    • Press the Path BPause.svg (Pause) button to pause animation for troubleshooting purposes
    • Press the Path BStep.svg (Single-Step) button for slowing down the animation, this functionality helps troubleshooting and resolving specific cuts and/or movements.
    • Press the Path BStop.svg (Stop) button to stop the animation.
  6. Press the Cancel button will remove the stock created for the simulation. If you press OK this object will be kept in your Job.


  • DataPlayback Speed: The speed of the simulation playback, in G-code lines/second
  • DataAccuracy: The accuracy of the simulation expressed as a percentage indicating the simulations deviation from the Job. For interactive simulation, reducing accuracy to 0.3 works much faster.
  • DataJob: The Job used as the basis of the simulation
  • DataOperation List: The list of Operations selected for inclusion in the simulation.
