Thank you for your relpy. I've already made it a whole polyline. For some reason autocad wouldn't do it automatically but i still got the problem with the radius. Since the endmill is 12 mm i think the neck radius is to small to fit when i run the cutter outside the Polyline. Also on the drawing there are 2 diffrent measures for the neck pocket? This is my first guitar build so please be patient with me But i'll try to mixture with the speeds and feeds tomorrow.
