While it is possible to "simulate" a CAM operation, it is not possible to "verify" steps, line-by-line that show the code being processed at that point. That makes it very difficult to fine-tune problematic g-code!
Below is a screenshot of F360 Simulate + with Info Tab open (NO G-CODE)

Here is the "Verify" process from Mastercam, which shows the LINE NUMBER, OPERATION AND G-CODE!

I know that to Verify as MC does, the verify would have to be undertaken AFTER posting an operation, but it should be possible to have an option to "Simulate" (no post) and "Verify" (undertake a post)
