I downloaded the HSMXpress (free version) I and I agree! It's the easiest CAM program I have ever tested! The best thing is that it's integrated to solidworks so you can do changes to the mdoel directly, and milling on "skecthes that doesn't exist" in the model, if you know what I mean. Like sketches painted on the surface.
Do you know if there is any differnce between Xpress and the one you have to pay for? The only thing I couldnt do was solid simulation, atleast what I found.
