I'm trying to make object with complex wholes. To simplify that made that with basic figures, but as i see subgroup works fine only when revolve's angle =360. Otherwise i see no effect. I was hoping that if j=1 in mask (closed top, side surfaces it), programme would consider that this object is closed/whole, same as when angle 180.
