With the upgrade from xp to win7 our cad/cam won't work anymore so we are looking for something new. All our drawings are made With Autocad and are then importen to the cam software. Now i've seen Some packages like Autocad/router cim, alphacamexpress or rhinocam. What would be a good package? We only use it for 3axis milling, but we do have a heidenhann scanner on the machine that we also like to use. This is how it works, we scan a surface from point a to b and than we Mill the line on the hight the scanner has detected. Our surface hasn't got a flat plane. The z plane has got his UPS and downs. Any ideas from anybody
