To view intermediate shaded simulations:
Click the 3D shaded
button or the rapid cut simulation
button and click the play
button.
Click on an operation to display the machined model up to that point in the process.
At the end of the list of operations is the word, Result. Click on this word to view the final simulation image for your part.

Note the you must turn on the 2D/3D shaded simulation option Save result files during rapid cut for this procedure to work for rapid cut simulations.
