Tool changes and rapid traverses are therefore read-in.  Likewise the CNC programs can be re-edited in the editor or be changed and  immediately reviewed by simulation. Because the simulation is running in the same graphical space, which is used for representation of a model or a component, possible differences can be detected at once (collisions or incorrect material removal).

Additionally when rapid traverses through the material with a too short cutter edge length the collision will be checked. The collision areas are hence marked coloured on the simulation model.  The respective lines are also coloured in the editor.
