Well, I'm trying to get featurecam to write a program (v12) for my 4th axis and im getting nothing but problems. Im trying to make a cylindrical shaped object that was modeled in solidworks and imported as a parasolid. I really cant define any features on the model, and the only surface i can define is done in the "surface milling" option. This always works fine for non-4th axis models, but now I just cant get it to go right. Is it even possiable to do a 4th axis operation from a complex model like this?
