I’m following your instructions for boolean, but not getting the same results as you. I’m sure I’m doing something wrong, but not sure what. I have 2 circles that I want to cut, at a point slightly off from center, on both sides. The end goal, is to then take the 2 semi-circles, and combine a smaller circle to each of the open ends, so that the original 2 semi-circles, becomes 1 semi-circle, with rounded tips. To ackomplish this, I drew 2 small rectangles, and laid them, one over each side of the 2 circles. The 2 circles are set to cut all the way through the material, whereas the rectangles are set to not cut at all. As soon as I combine the circles with the rectangles, the entire design goes black, except for the rectangle, which is now the only thing left of the design.
