# Need a nice smooth sweep (streamline 3-ax)

Phenom

Same problem as before, can't create a toolpath with a nice smooth spiral that sweeps along my surface with constant stepover on surface. Whatever I do, the streamline goes all funky at the top radiused part although the flow curves look perfect. If I interpolate 100 flow curves, they are spot on, still the path is messed up. What am I doing wrong?

Thanks/Harri

projection vector -> toward drive

and even you dont need to interpolate more flow curves

Thank you so much! I have little experience with streamline and just tweaked everything but with little or no success..

projection vector - tool axis - you had was projecting drive point in this "tool axis" direction so no tool path point was created on vertical faces ~ try to grasp it this way
