I have 35 years experience machining and programming , used mastercam for 19 years. after 3 years on solid cam i can say solidcam is faster. i have watched tutorials on mastercam and i say to myself , DUDE I WOULD HAVE BEEN DONE WITH THIS ALREADY ON SOLIDCAM. I am a full time programmer and i use solidcam. i really believe being able to verify all operations at once is the most amazing and best feature. i don’t know of any other cam software that can verify all ops at once. i always program my parts as many operations as possible with one program.
