im having a problem making a toolpath for a 3D design... the design is finished and i should be able to make the piece... but all i know is what i learned from the tutorial book that came w/ the program... it has about 8 different lessons... and only one goes over the 3D toolpaths... i have a part of the design that is an arc... and an angled part.... and but i am having a lot of trouble milling that... also the piece is a cross... and i want to get rid of all of the area around the cross so that the cross is protruding out of the metal... plz help me out...
