I know that the boolean operations never really work that well, but please bear with me. Im trying to make this curved surface with slots going through it sideways. I made 2 spline objects and then used a boolean substraction. As you can see it worked prett well except that my nice smoothly curved surface has become somewhat faceted. Any suggestions about a better way to go about this? The shape is exactly what I wanted except for the facets. Thanks folks. Max.
